ABOUT SECTION 8C FOR VEHICLES WITH INTEGRATED ELECTRONICS

A new system of integrated electronics was introduced on production in early 2001 at VINAAAAAA. The principal change involved the introduction of a central control unit (CCU) thattook over a number of functions within the vehicle electrical system, reducing the number ofseparate control modules. For example there is no longer a separate direction indicator relayor alarm ECU or rear door motion locking (IDDS) ECU. The CCU is located behind thedetachable glove box. The fuse box for those circuits that are controlled by the centralcontrol unit (CCU) is incorporated into the CCU itself. The fuses for the remaining circuits notcontrolled by the CCU are in a small separate fuse box immediately above the CCU. A newremote locking and alarm capable key fob with two buttons was introduced. There is also a‘touch key’ provided that overrides the immobiliser and optional alarm (where fitted).

The complete list of circuits controlled by the new central control unit is as follows.1.Flasher and hazard warning2.Rear fog lamp control3.Front fog lamp control4.Front screen wiper and washer system5.Rear screen wiper and washer system6.Central door locking system7.Front windows8.Courtesy lamp delay9.Speed transducer conversion for speedometer & taximeter10.Heated rear screen timer11.Immobiliser system12. Alarm13.Motion locking on rear passenger doors14.Intercom communication system15.Wheelchair seatbelt alarm16.Lights on warning

Note: At the time of writing (January 2001) these changes are only effective on Right HandDrive vehicles. Left Hand Drive vehicles built after VIN AAAAAA will be to the earlierspecification. Dealers should always refer to Technical Service Bulletins (TSB) for details ofup-to-date changes to the product.




Introduction

Each wiring diagram in this manual covers anindividual system on the vehicle. Each diagramis schematic, and wherever possiblecomponents are set out as on the vehicle -normally with the front of the vehicle to the topof the page. Only Right Hand Drive vehiclesfrom VIN AAAAAA are covered in this section 8C.For the wiring diagrams of all other vehicles referto section 8B.

Colour coded wiring is reintroduced and usedthroughout Integrated Electronics equippedvehicles. Each wire in the circuit is identified byits colour code (one or two letters) followed by anumber. The first letter is the primary colourcode of the wire, the second letter indicatingthe colour of any tracer marking on the wire.

The wiring colour codes and fuse layout andratings are shown in the table below and thediagram overleaf. The wire numbers shownfollowing the colour codes have no particularsignificance in service except to assist in theidentification of a particular wire if it is necessaryto seek assistance from the manufacturer.

The fuse box layout and fuse ratings are shownon page 5. The harnesses are shown on pages 6& 7. The locations of the ECUs and relays areshown on page 8. The locations of connectorsand earthing points referred to in the wiringdiagrams are shown on pages 9 &10. The termsleft, right, front, rear, LHS and RHS are relativeto the driving position, facing the front of thevehicle. For example, left hand front will be whatis colloquially known as ‘nearside front’.
