| Diagnosis and Testing Refer to Wiring Diagrams Section 417-01, for schematic and connector information. Special Tool(s) | | Terminal Probe Kit 29-011A | General Equipment Digital Multimeter. Diagnostic tool. 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. 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 the diagnostic unit can communicate correctly. NOTE:Ensure correct engagement of the wiring harness connectors. - Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection Chart | Electrical | - Fuse(s)
- Bulb(s).
- Electrical connectors.
- Switch.
- Vehicle wiring harness.
| - RESOLVE any obvious causes or concerns found during the visual inspection before carrying out any further tests. TEST the system for normal operation.
- 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. TEST the system for normal operation.
- On a vehicle without stored fault(s), continue according to the Symptom Chart and the corresponding symptom.
