Diagnosis and Testing

Refer to Wiring Diagrams Section 417-01, for schematic and connector
information.

Special Tool(s)

Inspection and Testing

NOTE: The generic electronic module (GEM) is part of the central junction box (CJB).
NOTE: A new GEM needs to be configured after installation. For this purpose, the vehicle-
specific data are read out of the module to be changed using WDS and is transferred to
the new module. REFER to:

Module Configuration

(418-01 Module Configuration, General Procedures),

Generic Electronic Module (GEM)

(419-10 Multifunction Electronic Modules, Diagnosis and

Testing).

NOTE: Before reading out the vehicle-specific data make sure that all electrical
connections in the vehicle are reconnected so that the module and WDS can communicate
correctly.

1. 1. Verify the customer concern.

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

Visual Inspection Chart

3. 3. Resolve any obvious causes or concerns found during the visual inspection before

carrying out any further tests.

4. 4. If the cause of the concern cannot be found by visual inspection, continue with the

symptom chart.
