The demand for HFO-1234yf refrigerant grows with each passing year as

more vehicle models require it. Currently about 50 percent of all new model

vehicles for 2018 are using HFO-1234yf. R-134a is predicted to be phased

out entirely in new vehicles across the United States by the year 2021, and

with vehicles that were early adopters of HFO-1234yf starting to come out

of warranty, it is important for technicians and service repair shops to be

prepared to be able to service these vehicles. This includes products and

tools specifically designed to meet the new SAE standards for HFO-1234yf

as well as technician training and certification.

Supercool is a packager and distributor of R-134a refrigerant gases for the

automotive aftermarket. With strict new EPA environmental regulations

regarding refrigerant cans requiring “self-sealing” valves, we have updated

our lineup of refrigerant products to meet these requirements.

Supercool also provides can taps, gauges and charging hoses specifically

designed to work with the new self-sealing cans. Whether your customer

needs R-134a or the new generation, environmentally friendly HFO-1234yf,

Supercool has a complete line of compatible lubricants, leak sealers and

detectors, system flushes, service couplers, service tools, dye/oil injectors

and more for both refrigerant systems.

I had the opportunity to meet our key-note speaker for MACS’ upcoming Nashville trade show and training event, and came away very impressed with NASCAR Xfi nity driver David Starr. When David asked me to attend the race in Mid-Ohio so we could

get to know each other and to discuss his key-note address to MACS, I jumped at the chance. Nonetheless, the wheels in my head also started turning and, before you know it, we were sponsoring David’s #52 Camaro for the race.

Just as a point of reference, the Mid-Ohio Sports Car course is about 45 miles from our nearest facility, and we never advertised to NASCAR fans in the past. However, the ability to not only attend the competition, but to also sponsor the #52 car for the race was a chance for us to reach a specifi c client base, potential technicians, and to be unique and different from our competition. We took a chance on this different advertis-ing medium to get our name in front of NASCAR fans and potential technicians, and it worked. In a short one-week window, we had 4,460 visits to our Facebook page, 1,145 likes, 127 entries into our contest, and 14 techni-cians requesting info about working for us; we ended up hiring one of the applicants.

I mention all of this to highlight four principles I truly believe in. One is to always be different and more unique than our competi-tion. Number two is to think outside of the box, and not simply do as others do. Three is to look at every opportunity, and fi nd the true return on investment (ROI), not just the expense in funds, time and energy. Lastly, see what your competition is not doing, and do it better than they ever can imagine.

On the surface, sponsoring a NASCAR event looked like it was out of our league; however, the ROI and results show that it was a worthwhile investment. Hiring just one new technician was, alone, worth the expense. We continue to host fundraisers for those in need, sponsor the local food bank, hold car washes for the scouts and pep squads. We sponsor and host the BBB public document-shredding events, sponsor local church bazaars, parades, and summer parishioner picnics and fairs. We participate in the “coats for kids” program and Toys for Tots. We sponsor our local schools’ sport teams, bands, and other events. And the list goes on and on!

The bottom line is, most people don’t care about how much we know, until they know how much we care about them and the community. I challenge you to think out-side of the box and become a part of your community, and I believe you will fi nd the ROI is more than worth the expense and effort. ❆

During the years that I’ve worked for the Society, I’ve had the good fortune to meet a number of the men and women who dedicate their careers in one way

or another to advancing the mobile air conditioning indus-try. Those who have helped design, develop, engineer, test, manufacture, install and sell or work on (and provide tech support for) the parts, equipment and vehicles we work with in the shop each day. Some of these individuals have been recognized by their fellow MACS members. and presented with the prestigious Industry Pioneer Award.

A little history: The Mobile Air Conditioning Industry Pioneer Award was originally established by IMACA (the In-ternational Mobile Air Conditioning Association) in 1988. In 2003, the Mobile Air Conditioning Society (MACS) World-wide assumed the role of continuing the tradition of recogniz-ing individuals who have made outstanding career contribu-tions to the mobile A/C and heat transfer industry.

Awards are presented each year at the annual MACS Training Event and Trade Show. During the Thursday lunch,

we learn who the winners are and receive a short career bio and explanation of some of their accomplishments. However, there’s so much more to their stories than can be presented during an afternoon lunch or in a magazine article.

That’s why we decided to launch the MACS Pioneer Video Series. The objective is to keep things simple (low key, low budget), and ask a few simple questions to better acquaint the audience with our Pioneers.

During the interviews I ask Pioneers about their back-grounds, where they grew up, where they went to school, and how they got started in this business. Some knew what they wanted to do, early on, because of a job they had as a teen-ager or something that they learned in college. Others had to figure it out on the fly as opportunities presented themselves. All went on to have distinguished, successful careers as tech-nicians, business owners, managers, engineers, scientists and educators.

We have a few inventors / patent holders in our Pioneer ranks, as well. Some have developed well-known designs, in-cluding evaporator cleaning devices and refrigerant recovery machines, while the inventions of others are more obscure, such as radiator sensor mounts and simple (yet ingenious) fan switch controls.

Part of the reason I got started on this project was to help share inspiring stories with our members. As big as the MACS community is, we’re still a small, tight-knit group, who love what we do and have a shared passion for A/C and climate control. Another catalyst: I’m also a big history buff, and the way I see it, we’re lucky to have many of the original Pio-neers still with us today. The ones who built our industry into what it is. They’ve taught us a lot already, but there’s still so much more to learn.

Pioneer award nominations can be submitted to Elvis Hoffpauir, MACS president and COO by email to [email protected]. All nominations are voted on and are at the sole discretion of the MACS Board of Directors.

Want to participate? If you are a Pioneer Award recipi-ent, who would like to participate in the MACS Pioneer Video Series, please let us know! Interviews, which generally take about an hour, can be conducted at the annual MACS Training Event and Trade Show or at another MACS event.

The Green New Deal resolu-tions, introduced in both hous-es of Congress this year, dealt

with climate change, and spurred quick and strongly divided reactions across the country. The Senate resolu-tion was defeated by a vote of 57-to-0, with 43 Senate Democrats simply voting “present” as to the resolution.

Opponents claimed the resolutions proposed wages for those unwilling to work and the elimination of live-stock, hamburgers and air travel. For us cheeseburger lovers, the Congres-sional proponents of the Green New Deal were not in fact proposing to eliminate hamburgers. Cows actually pass gas from both ends; accounting for more than 70% of livestock emis-sions of greenhouse gases that come from human activity.

The Green New Deal resolutions were not intended to be a law. They were an economic stimulus plan de-signed to have climate change cause us to confront issues such as the in-come inequality that will be aggravat-ed by a warming world. Per the U.S. Global Change Research Program’s Fourth National Climate Assessment report released in November 2017, future climate change is expected to have greater than average impacts on lower-income and other marginalized communities; groups with a lower ca-pacity to prepare for and cope with extreme weather and climate-related events.

The House of Representatives’ res-olution is only fourteen pages long, which might be a record for a Con-gressional “bill”. In referring to items published in the Fourth National Cli-mate Assessment report released last November, the resolution’s sponsors indicate, among other points, that “(1) human activity is the dominant cause of observed climate change over the past century;” and “(2) a chang-

ing climate is causing sea levels to rise, wildfires to increase and severe storms, droughts, and other extreme weather events that threaten human life, healthy communities and critical infrastructure to intensify;”. In setting the stage for the goals of the House’s resolution, it goes on to recite that the United States is currently facing “ (3) the greatest income inequality since the 1920s, with— (A) the top 1 per-cent of earners accruing 91 % of gains in the first few years of economic re-covery after the Great Recession;”. Per a news article published in the last week of May, the richest 10% of households in America own 70% of all the wealth in this country; the per-centage was 60% in 2000.

After setting the stage for the goals contained in the resolution, the actu-al proposed resolutions, which start on page 5 of the document, identify things the federal government should undertake as its duty. Among others, the federal government should “create a Green New Deal— (A) to achieve net-zero greenhouse gas emissions through a fair and just transition for all communities and workers; (B) to cre-ate millions of good, high-wage jobs and ensure prosperity and economic security for all people of the United States; (C) to invest in the infrastruc-ture and industry of the United States to sustainably meet the challenges of the 21st century; (D) to secure for all people of the United States for gener-ations to come—

(i) clean air and water; (ii) cli-mate and community resiliency; (iii) healthy food; (iv) access to nature; and

(v) a sustainable environment;”. The elimination of cars is not pro-

posed in the resolution. Instead, it seeks to have the government pursue goals and projects over a ten-year span, such as “(H) overhauling trans-

portation systems in the United States to remove pollution and greenhouse gas emissions from the transportation sector as much as is technologically feasible, including through invest-ment in— (i) zero-emission vehicle infrastructure and manufacturing; (ii) clean, affordable, and accessible pub-lic transit; and (iii) high-speed rail;”.

Supporters of the resolutions ar-gued that the resolutions were sim-ply setting goals to tackle dozens of the country’s social, economic, racial and historical ills while reducing the threat of climate destruction. Oppo-nents characterized the resolutions as an attempt to socialize the feder-al government and damage the coun-try’s economy while other nations can prosper. The debate by lawmakers over what to do about climate change, who is responsible for it and who should do something about it, like the debate over the extent of any such change, remains unchanged. The en-vironmental group, the Sunrise Move-ment, is evaluating and scoring the top presidential candidates on their commitment to fight for the equitable, sustainable, and prosperous future promised by the vision of the Green New Deal. Rankings will be released by the group throughout this fall. ❆

Videos are all the rage right now on social media. “Ensur-ing that video is an integral-

part of your strategy today is essen-tial,” says Lilach Bullock, a social media public speaker, author and con-sultant to media organizations.

“To put it simply, videos can help you build your brand, capture leads and gain customers on social media,” continues Bullock. “But there’s one significant challenge to video mar-keting for most businesses: How do you consistently create great social media videos on a limited budget? Fortunately, using the right strategies and tools, you can produce videos that meet your audience members’ expec-tations, and convince them to take ac-tion — without breaking the bank.”

Bullock shared six ways a compa-ny can create high-quality, affordable videos for social media:

1. Create a Video StrategyCreating videos on a budget re-

quires an effective strategy. This guides the whole process and helps avoid overspending. It also helps maintain a consistent brand voice that gets your message to your audience.

Important elements of an effective video strategy include:

● Identifying your ideal social media audience● Determining the avail-able budget for creating so-cial media videos.● Setting objectives for the shared videos.● Deciding the frequency and kinds of videos needed, based on the objectives.

2. Use Effective Video ToolsBypass the stress of shooting vid-

eos by using video tools to help cre-ate the footage. And – if you do shoot your own videos, these tools can edit the film.

Most video tools now provide tem-plates that can be customized to suit a brand and fit its message. For exam-ple, online tools such as Promo, Bi-teable, Moovly and Magisto provide a video template library that can be edited to make social media videos suited to your brand. Such templates also make it much easier to create vid-eo content consistently with very lit-tle investment. In addition, users can upload a video and edit it, adding text captions and calls to action – a critical aspect of video marketing.

3. Invest in Quality GearWhether you plan to shoot many

or just a few videos for social media campaigns, investing in quality video gear is vital. There are many pieces of equipment you can purchase, but Bullock says these four tools are es-sential:

● A digital camera.● A quality microphone; most built-in computer mi-crophones won’t deliver aclear sound for a brand vid-eo.● A tripod to stabilize the camera while filming.● A lighting kit that en-sures the video looks great.

4. Keep It SimpleYou are competing for an audi-

ence’s attention, so the best way to achieve results through your videos

is to keep things simple. When you’re sharing a video on social media, no-body is expecting James Cameron-like production quality. Most people just want to see a video that provides them with some value and looks good.

Whatever message you’re trying to convey, your videos should be as clear as possible. Know exactly what your message is (i.e., to increase brand awareness or tell your audience about a new product) before creating any video material, and find the simplest way possible to communicate it.

5. Keep It ShortBe aware that most social media

users have limited attention spans and patience.

Bullock points out video engage-ment drops sharply when it exceeds two minutes; other marketing experts say to keep it as long a commercial – 30 seconds, if possible.

When creating scripts for videos, it’s vital to keep them as short as pos-sible. For videos with speaking, keep scripts to around 300 words or less. Remember that not only do shorter videos keep your audience engaged, they mean less cost too.

6. Use a Smartphone with CareToday’s smartphones take great

videos – definitely good enough to share on social media. However, con-sider the impact you are working to create. Smartphones can create down-to-earth, grassroots videos that an audience can relate to, but if your in-tention is to promote a professional image, seriously consider using a real camera, or, at the very least, limiting smartphone videos to in-the-moment coverage of events. ❆

Tune ups, as they used to be called, include some of the fi rst engine repair work that

many new technicians undertake when they start working on cars as youngsters in their driveways. Many of their projects start with the thought that by simply replacing a few common wear items (spark plugs, ignition wires, air fi l-ters, and the like), the engine will perform bet-ter (maybe faster) and get better fuel economy. Sometimes that’s true, particularly when an en-gine is neglected or shows signs of performance issues, such as a misfi re or rough idling. But, in many cases, any improvements are negligible. More important, these small jobs function best as teaching exercises, giving new technicians experience with using their tools, specing out and buying the correct parts for a vehicle. If given enough time and a fl eet of varied vehicles to work on, they learn how to recognize what looks right and what doesn’t.

Eventually, these technicians are going to face engines that present unexpected condi-tions. Wiring that has been chewed on by ro-dents, no-starts with no-codes, and even the

occasional “fl uids where they don’t belong” (or shouldn’t be found) scenario.

This may be the case for technicians work-ing on certain 2010-on GM vehicles with 3.0-li-ter or 3.6-liter engines, particularly if the cus-tomer complaint has to do with an oil or coolant leak when the check engine light is on.

Upon inspection, technicians may fi nd mis-fi re codes in the PCM, along with large amounts of oil or coolant in the spark plug tubes. They could also notice that oil is not leaking into the tubes from the areas above. This might be the case on many engines where the spark plug holes are located underneath the valve cover, where the gasket could leak oil and drip down along the outside of the head, and ultimately into the spark plug bore. This was quite com-mon on older engines with cork valve cover gaskets, which would quickly deteriorate over time due to thermocycling. However, there’s no sign of that problem on these engines; it’s as if the oil or coolant is mysteriously coming out of nowhere. In this situation, it’s possible that the oil or coolant may actually be leaking right

through the aluminum-alloy head itself, as po-rous spots may have been inadvertently created during the manufacturing process.

There’s not much that can be done when presented with a situation like this, other than to replace the cylinder head itself, and install a new head gasket, spark plugs and even coils if they are contaminated. The reason is that al-though the spark plug tubes may be the prob-lem, they are permanently sealed into the head during manufacture and are not replaceable individually.

GM has identifi ed concerns similar to this in the sixth revision of their long-running PI (Preliminary Information) bulletin PIP5095F: Fluid in Spark Plug Tubes. In it the manufac-turer identifi es several models, including Buick Enclave, LaCrosse and Regal, along with Ca-dillac ATS, CT6, SRX and XT5, Chevrolet Ca-maro, Caprice PPV, Colorado, Equinox, Impala and Traverse, as well as GMC Acadia, Canyon and Terrain. Engines include the LF1, LF3, LF4, LFW, LFX, LFY, LGW, LGX, LGZ and LLT variants. ❆

Not too many years ago, diag-nosing a heavy-duty A/C sys-tem for no-clutch engagement

was a straightforward process. To perform a quick check to determine if the A/C clutch would engage, all you needed was a jumper wire. Then, with the ignition turned to the run po-sition, you found the binary switch, disconnected the connector and used the jumper wire to bypass the switch. If the A/C clutch engaged, that would indicate one of two possibilities, A faulty switch or a low refrigerant charge. If the clutch did not engage, then you would have to dig a little deeper. The problem may have been a blown fuse, poor grounds, a faulty re-lay, A/C request switch in the control panel failure, wiring harness issues, such as loose connections, backed out pins or corrosion. Or, the clutch field coil may have failed.

Fast forward to modern equipment, and we are now dealing with a differ-ent set of equations! For example, the A/C clutch controls found in the light duty world that are ECM controlled, this is the world we now live in! For the A/C clutch to engage, there is a new strategy. When the Blower switch is in any position except OFF and the

A/C switch is in the ON position, the following conditions must be met: En-gine RPM of a minimum 450 rpm, ve-hicle air pressure above 60 psi (when equipped with an air driven fan), am-bient temperature above 40 degrees F., refrigerant system pressure above 34 psi, evaporator temperature above 40 degrees F., and battery voltage above 12.0 volts. Once ALL these conditions are met, the A/C clutch will be en-gaged through a control module, a re-lay or a field effect transistor (FET).

If the listed conditions are met, and the compressor clutch will not engage, the jumper wire won’t help us! The new process begins by check-ing for any DTCs. This check is per-formed either with software, or on many applications, the fault codes can be accessed through the Driver Infor-mation Center located in the dash or instrument cluster. Remember that Engine DTCs, such as high coolant or oil or charge air cooler temperature, will deny A/C clutch engagement. If there are no codes present, the next process is a visual inspection: Is the A/C fuse good? Are the drive belt and tensioner in good condition and work-ing properly? Is the condenser clean, is the compressor clutch air gap cor-

rect, does the clutch show any signs of overheating, and does the compressor rotate without any grinding or rough-ness as it turns?

Next check the A/C system pres-sure. As a rule of thumb, if the charge level is enough, the static gauge readings will be close to ambient temperature. With engine running and the A/C request button activat-ed on the dash, check for voltage at the compressor clutch battery feed; the voltage should be within 2 volts charging system voltage. If voltage is not present or falls below the expect-ed value, check for data line inputs. Additionally, check each connector in the A/C circuit for loose pins, back-outs and corrosion. If the voltage is correct, perform an ohm check of the field coil. A good coil is usually about 3-4 ohms for 12volt systems and 14-18 ohms for 24volt systems. Check the ground side of the circuit for loose or dirty connections and backout pins.

For computer-controlled A/C systems to function properly, they must have the correct voltage, which are very sensitive to loose-fi tting connectors. Be sure to check these items carefully during the trouble-shooting process! ❆

Pre-post scanning your customers cars? Be shop wise and understand the consequences of the outcome, as well as being service ready, if the customer says “OK, fix it!” (See scan tool report below.)

The car, a 2012 Lexus IS350C with the 2GR-FSE direct injected 3.5L engine (Figures 1, 2), was scanned during a routine service, and the shop noted two DTCs in the A/C system for the solar sensor circuit (Figure 3, highlighted in red boxes). They were “current codes,” and the tech-nician advised the shop owner of his findings. This shop doesn’t perform any A/C service beyond basic refrigerant recovery and recycling, so they asked us to look at it.

Is there truly a problem with the solar sensor or its re-lated circuits? If so, why are there no complaints about the A/C or heat from the customer? Is it possible this is normal behavior? This now becomes the quest for the shop searching for answers during a routine service. These are what I call service snags. If we are to investigate this is-sue, we must have a solid plan to ensure being paid for the service we are about to perform. If our exploration reveals evidence of normal A/C system behavior, what do we do then? What we don’t know can hurt us in the end.

Note: Although there were navigation DTCs, the shop didn’t concern itself with those DTCs, as they were history DTCs and not current.

Adding services to the menu of vehicle service choices traditionally brings benefits to the customer along with in-creased income and, hopefully, profit to the shop. Offering a value-added service, such as headlight reconditioning during an oil and filter service brings a nice strong profit into the service facility – and restores the night vision lu-mens the headlights once had.

Pre and post scanning Lately, industry press releases are featuring strong em-

phasis in the area of conducting pre and post scanning with a vehicle-capable scan tool. For the purposes of this column, I’ll reserve the many reasons why shops perform such a service. Let’s just say, for a moment, the car came in with an A/C complaint of “the air doesn’t seem cold enough.” The shop begins by doing an A/C service with their RRR machine, but never really checks the whole sys-tem for leaks. You agree that, at least temporarily (based on the severity of the leak), the system would be blowing colder air than when it came in. The technician falsely believes all is satisfactory with the car. He, thus, releases it because the “air not blowing cold enough” complaint is solved. (This never happens…right?) The customer leaves, and everything seems fine.

What would happen if we grabbed a scan tool instead of the A/C machine to work on the same car? The scan tool shows a DTC for the air recirculation door actuator, as well as a rear blower motor DTC. Aha, the vehicle doesn’t just have a refrigerant leak; it has DTCs for other compo-nents related to climate control system performance. You see that the direction of service is now completely differ-ent from what it was a moment ago, isn’t it?

Do we fix the A/C complaint and never mention the scan tool findings? That wouldn’t be a very prudent thing to do. We know potentially the direction that phone call will go after the customer picks up the vehicle, don’t we? “Hey, the blower motor still isn’t working in the rear!” You get the point.

Really, what harm can possibly come from completing a pre-post scan on a customer’s vehicle? Well, that depends on the outcome of the scan tool report, doesn’t it? If the report indicates all modules are happy and reporting no DTC’, we would present a satisfactory report card to our client, which should please him.

Conversely, what if the report has something of interest? Perhaps performance DTCs for the high voltage battery on a hybrid vehicle. What if there are DTCs in the ABS module, and it’s in for a brake job? What if the report indicates there are DTCs in the HVAC system and it’s in the shop for an A/C service? You can imagine what the outcome may be if we serviced the A/C system and nev-er caught the code for a front blend door actuator on the passenger side. Are we prepared to report our findings and

proceed with a diagnosis, if necessary? Remember, many HVAC problems do not illuminate the Malfunction Indi-cator Light (MIL). Frequently, it’s a function that begins to deteriorate or a behavior that’s not responding the way the customer is accustomed to. These problems need to be addressed, assessed and dealt with by the service advisor and technician, and finally the customer. Are these prob-lems old and a previous shop never cleared memory or are they currently an issue?

Although many technicians have been printing scan tool data for decades, it seems to be the hot topic among not just mechanical shops, but collision repair centers, as well. I understand collision shops have a whole plethora of reasons to perform a pre-post scan on vehicles, which is beyond the scope of this article, so we’ll reserve that topic for a later date.

The more information we see on reports, the more ques-tions we will be faced with as a service facility. Especial-ly, if the shop is new to connecting to the OBD port to per-form a routine pre-post health scan. My recommendation is to make sure if you’re going to pre-post scan vehicles, you must have properly trained, skilled technicians at the ready to take on the required work that accompanies the added testing. Technician prowess is the key here! Hope-fully, we have it and, if not, at least have access to a shop willing to do the work for you.

Back to the Lexus IS350C. First things first, lets see what the data looks like. Please read through Figures 4 through 12, in that order.

It is time to get our service information out, and look at


Figure 4: The correct vehicle has been identifi ed in the scan tool and we confi rmed the correct vehicle identifi cation number. (Peter Orlando / Autel Maxisys 908)

November/December 2019 • ACTION 21

what it says for this solar sensor operation. We’ll also have to look at the DTC set criteria.

According to Toyota service information:


Figure 5: Our fi ndings during an all-module scan coincide with the fi rst shops DTC scan tool report. We have two DTCs in the A/C module. (Peter Orlando / Autel Maxisys 908)

Figure 6: Continuing with our analysis, we see we have the same B1421 and B1424 solar sensor codes as the print-ed Autel scan tool report showed. (Peter Orlando / Autel Maxisys 908)

Figure 7: Inside the shop, we have data optimized to support the solar sensor PIDs in question. (Peter Orlando / Autel Maxisys 908)

Figure 8: Shining a bright light onto the solar sensor. (Peter Orlando)

Figure 9: When we expose the sun load sensor to more light intensity, the value (count) goes up as indicated by 18 for the driver side solar sensor and 24 for the passenger side. Right at this moment. there doesn’t seem to be anything wrong with these readings. (Peter Orlando / Autel Maxisys 908)

Figure 10: Then we brought the vehicle outside and moni-tored the solar sensor again. (Peter Orlando)


The solar sensor detects sunlight and controls air con-ditioning AUTO mode. The output voltage from the solar sensor varies in accordance with the amount of sunlight. When the sunlight increases, the output voltage increases. As the sunlight decreases, the output voltage decreases. See Figures 13 through 16.

Digging a little deeper on the DTC set criteria, we noticed some detailed information about the air conditioning system on the Lexus. B1421 or

B1424 DTC can set if the vehicle is checked in a dark area. We needed to be clear about the ambient light conditions in the shop. We have skylights every 20 feet in the roof, so there is plenty of natural light entering the shop fl oor space. We noted that as soon as we had about 35-40 on the solar sen-sor count, it set false DTCs against the solar sensor circuits.

This is a normal system behavior, and no repairs should be attempted at any time.

Here is the B1421/B1424*3 (footnote) from Toyota/Lexus on the solar sensor DTC set conditions.


Figure 11: This is the count signature we observed when the vehicle was exposed to outdoor sunlight. The data is track-ing equally and showing no indication of any malfunctions. (Peter Orlando / Autel Maxisys 908)

Figure 12: All seems to be satisfactory as the sensor re-sponds accordingly to light intensity. The count eventually went to 139 as it appears above. (Peter Orlando / Autel Maxisys 908)

Figure 13: The A/C amplifi er detects changes in the output voltage from the solar sensor (shown here) mounted to the top of the dash toward the passenger side of the vehicle. The data from Lexus is very limited as to its normal opera-tion. (Peter Orlando)

Figure 14: This sensor is a combination sensor for the driver and passenger side of the car, and we now have proof it’s working exactly as Toyota/Lexus describes. Our counts on the scan tool are increasing as the brightness increases. (Motologic)

Figure 15: As we continued with our testing, we brought the vehicle back into the shop and noticed the number of DTCs PID incremented to 2. (Peter Orlando / Autel Maxisys 908)

Figure 16: We drove the vehicle back outside and, within seconds, the Number of DTCs went back to 0. This seemed very odd, so we needed to do some more research. (Peter Orlando / Autel Maxisys 908)


*3: If the check is performed in a dark place, DTC B1421/21 or B1424/24 (solar sensor circuit abnormal) may be output.

The A/C amplifi er memorizes the DTC of the respective malfunction after 8.5 minutes; it will set the solar sensor DTCs if it recognizes the vehi-cle is in a darker than normal area.

Look at the scan tool data Time Stamp on (Fig 15) when it set the dy-namic DTCs. We were roughly at 11 minutes of runtime, approximately 3 minutes beyond the 8.5-minute timer for the A/C amplifi er to set the codes. We chalk this one up to education, and move on.

If a shop was to chase after this type of DTC believing there truly is a problem, they will surely waste a lot of time and end up with a very up-set customer. This is the importance of having good service information, being smart about our diagnostics and using critical thinking skills to navi-gate the concern. In this case, the devil was in the details of the diagnostics.

The devil is in the details of our diagnostics: What are the conditions?

We had an interesting conversation while reading how Toyota/Lexus adjusts the heating and air conditioning system functionality details on the IS350C. (Remember this car is a convertible.)

Toyota/Lexus uses what they refer to as a neural network control for the climate control system. This control can affect the HVAC functionality by artifi cially simulating the information processing methods of the nervous system of living organisms in order to es-tablish an input/output relationship that is similar to the human brain. (Yes folks, time to raise the labor rate.)

With previous HVAC (without neural network control) systems, the climate control system determined required outlet air tempera-ture and blower motor air volume settings using inputs from vari-ous sensors and calculation formulas. Since people’s senses are di-verse and complex, a given temperature is sensed differently by the occupants, depending on the environment in which those people are situated. Example: Given a certain amount of solar radiation, a person may feel comfortably warm wearing a sweater in a colder climate, or extremely hot in a hotter climate. In a neural network, the data has been collected under varying environmental condi-tions and stored in the air conditioning system amplifi er assembly.

Therefore, air conditioning performance can be optimized based on whether the convertible hardtop is open or closed. An exclusive air conditioning system control can be adopted for use when the convertible hardtop is open in order to reduce passenger discom-fort due to airfl ow coming from the rear of the vehicle while driv-ing with the top down. The system allows occupants to ride com-fortably in ambient temperatures from 41°F (5˚C) to 95°F (35˚C).

The retractable hardtop open air conditioning control cancels cabin temperature correction and automatically corrects the outlet air temperature in accordance with outside air temperature, amount of sunlight and set temperature criteria when the retractable hard-top is open.

Input processing, which takes the selected temperature setting along with sensor and switched inputs, sends it over to the con-trol logic in the A/C amplifi er. Toyota then uses what they refer to as layering to adjust the output processing to optimize the climate control system for passenger comfort.

Neural networking considers:• Target outlet temperature• Amount of sunlight correction• Target airfl ow volume• Outlet modeTherefore, the sum of the input, intermediate, and output layers are ad-

justed to provide an enhanced air conditioning comfort based on the actual environmental conditions the occupants are in.

Some features of the neural network are customizable, and can be mod-ifi ed to adjust passenger compartment comfort when the retractable hard-top is open or closed.

What are the conditions for testing? The manufacturer usually provides us with the testing conditions they need the vehicle to be under or at in order to conduct a proper A/C performance test. In this case, it just may be at 70 MPH with the top down.

Terms, conditions, and defi nitionsSo, we spent some time discussing the neural network capability on the

2012 Lexus IS350C. This car is not a diesel!

Something else that is interesting, this car comes with glow plugs. I know what you’re thinking: “But Pete, it’s not a diesel!” You are correct, and it doesn’t have to be a diesel in order to use glow plugs. It goes to prove once again that the terms the OE chooses to describe components don’t have to be in accordance with components or systems we’re familiar with.

2012 Lexus IS350C — glow plug control — fuel economy enhance-ments

The A/C amplifi er and ECM operate two glow plugs in the engine cool-ant to reduce the increased fuel consumption during cold start—and -- to improve heater performance. See Figures 17, 18.


Figure 17: The GLW RLY turns on when it receives a ground signal from the A/C amplifi er. (Motologic)


Fused B+ voltage is supplied to terminal 1 of each of the glow plug relays. The A/C amplifi er supplies ground for GLW relay 1 at pin 23 and ground for GLW Relay 2 at pin 4. Once either of these two relays are grounded by the A/C amplifi er, fused B+ power is sent through the latch portion of the relay and to each water by-pass glow plug. The glow plugs’ housing provides indepen-dent ground for each glow plug.

The air conditioning amplifi er as-sembly and ECM control this oper-ation. The air conditioning amplifi er assembly determines the number of

glow plugs to operate based on the coolant temperature, outside tempera-ture and A/C Max. Hot state. The air conditioning amplifi er assembly then transmits request signals to the ECM.

Based on the request signals from the air conditioning amplifi er as-sembly and a voltage generation rate signal from the alternator, the ECM transmits a glow plug operation permission signal to the air conditioning amplifi er assembly. See Figures 19 through 22.

Note: The A/C amplifi er and glow plug system do not set any DTCs. There is a positive temperature coeffi cient (PTC) test listed in Toyota ser-vice information to assist with diagnosis of this system. This PTC test is performed using the Techstream or equivalent scan tool in conjunction with the wiring diagram in Fig.17. The test will provide guided No Good (NG) vs OK information to determine if any defi ciencies are in the circuit.

Summary: Next time we’re working on a gas engine vehicle (especially those of us in colder climates), and we call the parts store for a set of glow plugs, we may have some explaining to do.

As always…thanks for playing. ❆

From September 16th to September 20th, 2019, MACS was pleased to host the Automotive Electronics and Software boot camp presented by Dr Mark Quarto of Future Tech Automotive. There were 17 students who attended this fast-

paced and hands-on class representing all segments of the industry, including service technicians, educators, and en-gineers both heavy duty and light duty, from all over the U.S. as well as Canada.

The course began with the basics of Ohms law, resis-tive circuits and the calculation of power used by compo-nents. This first section serves as an introduction for the less experienced students and a refresher for the more ex-perienced students, ensuring that everyone possesses the foundation of knowledge needed to proceed on to more complex electronics.

The course moves on from basic circuits into solid state electronics, such as diodes and transistors. We explored how different types of these components worked and cov-ered where each would be used in automotive systems. Dr Quarto keeps lecturing to a minimum, preferring to teach theory through practice. Much of the time in class is spent building circuits that mimic those we would find on cars. Tasks include controlling a compressor relay and regulat-ing the speed of a blower motor by controlling a field ef-fect transistor. We then used meters and oscilloscopes to analyze how the circuit functioned. Skills learned here can be taken directly back to the shop and applied to test-ing our customers’ cars.

The class moved from discrete components driven by analog voltages to controlling circuits with a microproces-sor. Dr Quarto uses the Arduino family of microcontrol-

ler, which every student gets to keep after the course is over. Arduino con-trollers, which accept both analog and digital inputs, are capable of produc-ing analog and digital outputs, just as a controller does. Many of the same circuits were built to be analyzed, but instead of controlling with potentiom-eters and switches, are controlled with the Arduino. We supplied the Arduino with inputs, such as A/C request and blower speed request, and asked the Arduino to drive a transistor to spin a motor based on inputs. Sounds fa-miliar, right? This project not only involved building circuits but writing the code to control the circuit as well, subsequently outputting the values of the inputs to the computer screen as a scan tool does. This gave the students a deep understanding of what is going on inside the modules we are working with on the car.

The course concludes with a final design project. Students are asked to design a circuit to control a com-pressor relay based on inputs from a an A/C pressure sensor to the Ardu-ino, output the relay status and fuel pressure to a screen (scan tool) and illuminate a malfunction indicator light if the pressure is out of range high or low. The students were giv-

en the specs for the project and were charged with applying all the knowl-edge gained in the class to design the circuits and write the algorithms to control the circuit.

I highly recommend this course for anyone with a goal to expand their

knowledge of electronics with infor-mation they can take back to the ser-vice bay to help fix cars.

Editor’s note: Futuretech will hold a part 2 of this class at MACS Train-ing Facility October 5-9, 2020. ❆

CCAR provides complimentary on-line AGM Battery Safety course

CCAR (The Coordinating Committee for Automotive Repair) is pleased to provide an online Safety course focused on Absorbed Glass Mat (AGM) batteries. The course – de-veloped by CCAR and ShipMate, Inc. – is the fi rst in a series of complimentary online safety courses resulting from CCAR’s agree-ment with the U.S. Department of Labor’s Occupational Safety & Health Administra-tion (OSHA) Alliance partner program.

The online AGM Battery Safety course is being offered on a complimentary basis. To sign-up and access the course, please visit www.ccar.training or call CCAR at 888/476-5465. Those who complete the course and pass the fi nal exam are offered a certifi cate of completion.

“More than 40 million vehicles in the U.S. alone are now utilizing an AGM bat-

tery” said CCAR’s President, Charles E. Ayers. “AGM batteries, which have been installed in vehicles since the 1990s, are commonly found in most of today’s hybrid vehicles as well as in many vehicles that use stop/start technology”.

AGM batteries typically provide high-er cranking power and reserve capacity as compared with traditional fl ood-acid (FLA) batteries. They are labeled as “non-spillable” and are often mounted in non-traditional lo-cations (such as in the trunk of the vehicle). Because they are sealed, they should NOT be charged using conventional FLA battery chargers.

The CCAR and ShipMate online courses offered now include:

• Surface Transportation of Automotive Hazardous Materials (available in English and Span-ish)• Surface Transportation of Automotive Dangerous Goods - Canada (available in English and French)• Multimodal Transportation of Automotive Dangerous Goods (available in English and Span-ish)• GHS Hazard Communica-tion Standard; and• A full suite of automotive safety courses

Bergstrom and Viatec partner to provide package of no-idle options for utility trucks

An idling utility truck is common. In order to supply power to the lift, the truck must idle.

Bergstrom and Viatec understood there was a better way to do provide power, so they set about innovating the technology to develop solutions.

Viatec, a new engineering-focused com-pany, created SmartPTO, an electric power takeoff unit that is the fi rst of its kind. Berg-strom, a long-time innovator of HVAC sys-tems, created the new eCoolParkTM system – the only compact high-effi ciency, electric no-idle A/C system.

Now utility trucks are reaping the bene-fi ts. A SmartPTO upfi tted truck can save up to 1,890 gallons of fuel annually and elim-inate approximately 42,300 lbs. of carbon dioxide.

One stand-out is that both systems can be integrated into existing vehicles. eCool-Park can be integrated into existing vehicle HVAC systems, and its compact size allows it to be installed in multiple locations, in-cluding within the vehicle’s condenser, in the engine bay or through a remote-mount-ed compressor and condenser assembly. It utilizes SmartPTO’s battery capacity for


its operation. SmartPTO has the option of adding additional battery capacity, as well – thereby providing the required power for increased AC time.

SmartPTO, which can be easily in-stalled, helps reduce maintenance costs by 69%. The non-invasive build of SmartPTO typically allows the unit to be installed on in-fi eld trucks in less than two days. Should a heavy-duty cycle on any given day utilize all of SmartPTO’s battery, the truck can simply be switched to operate its conven-tional PTO. Due to the elimination of idling, trucks have much less wear and tear on their engines, and as a result, their resale value is increased by 25-30 percent.

Four Seasons introduces brushless direct current motors

Four Seasons® introduces brushless direct current (BLDC) motors, manufac-tured in-house with higher speed ranges, longer operating life and higher effi ciency over brushed and pulse width modulation (PWM) motors, according to Ron Miller, director of marketing, Four Seasons.

“BLDC motors are rapidly on the rise in the automotive aftermarket,” said Mill-er. “This sophisticated technology fi rst appeared in the mid-1990s on GM appli-cations and has gained popularity with OE over the years. Four Seasons’ commitment to providing our customers with a quality BLDC motor begins with our experienced manufacturing and engineering capabilities to ensure OE performance.”

Brushless motors are true to their name and utilize electronic sensored or sensorless commutation instead of a brush card. Brush cards degrade over time, causing motor fail-ure. Brushless motors fulfi ll a greater range of applications than brushed motors and are more effi cient by design, with characteris-tics such as quieter operation, greater speed control and less weight than the brushed de-sign.

In between the evolution of the brushed design and brushless technology, the PWM-controlled motor was developed. PWM is a digital signal generated from the vehicle’s engine control module, which is capable of controlling and varying the speed of the electric motor. Brushed motors, in conjunction with an attached PWM control module, can be used in some brushless ap-plications; however, a brushed motor cannot be used as a direct replacement in brushless applications. Attempting to do so can result in poor performance, damaged components or thermal events due to the differences in the electronics controlling the motor and HVAC system.

INFICON introduces D-TEK® 3 re-frigerant leak detector

The new INFICON D-TEK® 3 Refriger-ant Leak Detector provides service techni-cians fast, accurate leak detection that mini-


mizes the cost and environmental impact of escaping refrigerants. D-TEK 3 is built on the proven technology and unparalleled per-formance of the company’s D-TEK Select Refrigerant Leak Detector, a market-leader for refrigeration and air conditioning service worldwide.

Recent changes in government regula-tions, driven by concerns over global warm-

ing and ozone depletion, have led to more stringent requirements for refrigerant leak checking of cooling systems. D-TEK 3 can quickly and reliably locate CFCs, HCFCs, HFCs and HFOs, blends (including A2Ls). In addition, with the optional CO2 sensor, this hand-held unit can also detect CO2 leaks making it a cost-effective alternative for service technicians that traditionally must carry two separate instruments to cov-er this range of gasses.

D-TEK 3 provides user confi dence with a 1 g/year sensitivity which does not degrade over time. Service technicians will especially like the 10-hour battery life and simple fi eld replaceable sensor that mini-mize downtime and optimize service calls. D-TEK 3 Refrigerant Leak Detector comes with a rugged carrying case, and has a two-year replacement warranty.

In mid-September, one of eight HVAC units serving the MACS headquarters failed. That occurred on the Friday before a week-long training event involv-ing almost 20 participants was scheduled to commence, and as Murphy’s law

would have predicted, the failed unit served the classrooms where the training was scheduled to take place. Liberal use of fans to move air from building zones with working A/C made the situa-tion manageable, if not ideal.

We hadn’t given much thought to the build-ing’s HVAC, other than scheduling preventive maintenance and occasional repairs. However, with the one unit’s failure came the realization that all the remaining HVAC equipment was as old as the building and had about 20 years of mileage on it.

HCFC-22 (also known as R-22) has been the most common refrigerant in residential and many commercial heat pumps and air-conditioning systems for many decades. As R-22 and other HCFCs are phased out, manufacturers of these A/C systems are offering equipment that uses ozone-friendly refrigerants. While these replace-ment refrigerants, primarily R-410A, do not deplete the ozone layer, they do lead to climate change, therefore they need to be handled responsi-bly to avoid releases to the atmosphere.

Currently, domestic chemical manufacturers may no longer produce new R-22, and importers may no longer import that refrigerant. Existing domestic stocks can be used to service existing equipment (this will no longer be the case after 2020); which means that after 2020, only recycled, reclaimed, or previously produced R-22 can be used to service existing equipment. As one would expect, R-22 has become very pricey.

At MACS, we have a total of eight rooftop units, seven charged with R-22, and now one new one with R-410A. It’s only a matter of time when all the older units will have to be replaced, but barring a spate of failures, that can be handled over a period of time.

And R-410A? Our HVAC contractor explains; “At this point, R-410A refrig-erant is slated to be phased out of all residential equipment by the end of 2023. I was told, as of today, there is no exact date for phase out in the commercial arena. ‘Stay tuned,’ is what I was told. My experience tells me most likely by 2026.” ❆
