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 circuitswhich are connected to earth from the same line; this facilitatesfault finding if a problem involves more than one function: forexample, the corrosion of one earth could put different circuitsand several functions out of action at the same time.
Functional descriptionThe earths on the vehicle are divided according to the variouswiring they belong to.Radiator wiring:battery earth, C01 A
Front wiring:left front earth, C10 ABS front earth (at left corner), C12 electric steering front earth, C14earth on tunnel, C38
Dashboard wiring:passenger dashboard earth, C20 A, C20 BAir Bag system earth, C50
Rear wiring:passenger dashboard earth, C20 C, C20 Dleft rear earth, C30right rear earth, C31earth for amplifier, C056
Battery negative wiring:battery earth on engine (on gearbox), C02battery earth on bodyshell, C03
Engine wiring:battery earth, C01 A (JTD engine only)earth on engine, C40 (petrol engine only)injection control unit earth, C60 (JTD engine only)compressor earth, C39
Air conditioning wiring:air conditioning unit earth (on right side of dashboard),C16
