Description

The following diagram shows the various earths on the car. The associated circuits are shown for each earth.This makes it easy to identify the earthed circuits on an individual line: faults and failures are therefore easier to locate in the case of problems that affect more than one function: for example, oxidation of an earth may put several circuits and numerous functions out of service simultaneously.The earths present on the vehicle, categorised according to their relationship with the various wires, are as follows.
