DESCRIPTION - EARTHS - Alfa Romeo 159 1.9 JTD 16V Da 01/06
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.
