DescriptionThe following diagram shows the various earths on the vehicle, and the circuits connected to each are indicated.It is thus easy to identify the circuits which are connected to earth from the same line; this facilitates fault finding if a problem involves more than one function: for example, the corrosion of one earth could put different circuits and several functions out of action at the same time.
Functional descriptionThe earths on the vehicle are divided according to the various wiring they belong to.Radiator wiring:battery earh, C01A Front wiring:left front earth, C10 right front earth, C11 ABS front earth (at left corner), C12 battery earth, C01B (JTD version only)Dashboard wiring:driver's dashboard earth, C15A driver's dashboard earth, C15B Air Bag system earth, C50A Rear wiring:driver's dashboard earth, C15C left rear earth, C30 right rear earth, C31 rearscreen earth. C32 earth on centre tunnel, C38 Air Bag system earth, C50B Battery negative wiring:battery earth on engine (on gearbox), C02 battery earth on bodyshell, C03 Engine wiring:earth on engine, C40A-B-C Air conditioning wiring:air conditioning unit earth (on right side of dashboard), C16 BOSE system wiringBose system earth, C65
