223001397 - E1020 EARTHS - DESCRIPTION (MY 2005)

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: this aids fault and failure detection operations if problems affect more than one function, e.g. oxidation of an earth may put several circuits and numerous functions out of action simultaneously.

some earths belonging to the same wiring are connected to one another via the various welding on the actual wiring.

This allows all the electrical components on the same wiring to be earthed even if a particular earth point cannot allow effective contact with the vehicle body.
