General Equipment

Inspection and Verification

NOTE: The generic electronic module (GEM) is part of the central junction box (CJB).
NOTE: If a new GEM module is being installed, the new module must be configured following installation. For this purpose, the vehicle-specific data is
read out of the module to be changed using the diagnostic unit and is transferred to the new module.
NOTE: Before reading out the vehicle-specific data make sure that all electrical connections in the vehicle are reconnected so that the module and the
diagnostic unit can communicate correctly.
NOTE: Ensure correct locking of the wiring harness connector.
NOTE: The rain sensor module is also responsible for actuating the automatic headlamps.

1.

1. Verify the customer concern.

2.

2. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection

3.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. CHECK the

operation of the system.

4.

4. If the concern persists after the visual inspection, PERFORM a fault diagnosis with the diagnostic unit and RECTIFY any displayed faults in

accordance with the displayed fault description. CHECK the operation of the system.

5.

5. On a vehicle without stored fault(s), continue according to the Symptom Chart and the corresponding symptom.

6.

6. After testing or rectifying the fault and after completion of operations, READ OUT the fault memories of all vehicle modules and DELETE any stored

faults. READ OUT all fault memories again after a road test.
