Compass: Description and Operation

Compass System

• Before troubleshooting or servicing, the technicians must be familiar with the function and operation of the compass system. Refer to the Owner's Manual.

• Use "Guided Fault Finding" when servicing or performing Fault Finding with the Vehicle Diagnostic Tester.

• After connecting the battery, check all the vehicle accessories, for example, the radio, the clock, the Comfort packages. Refer to and the Owner's Manual.

• By the use of magnetically adhered antennae on vehicle roof, there is the hazard that the compass module will malfunction due to magnetic influence and remaining magnetization of the vehicle roof. For complaints of inaccurate or faulty direction displays on the compass module, ask the customer whether a magnetically adhered antenna is being used before starting repair work.
