Inspection and Testing

NOTE:
NOTE:The generic electronic module (GEM) is part of the central junction box (CJB).
NOTE:
NOTE:If a new generic electronic module (GEM) is being installed, the new module must be configured following installation. For this purpose, the vehicle-specific data or the data to be changed is read out of the module using WDS and is transferred to the new module. REFER to:
Modul-Konfiguration (418-01, General Procedures),
Zentralelektrikmodul (GEM) (419-10, Diagnosis and Testing).
NOTE:
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.
NOTE:
NOTE:Ensure correct locking of the wiring harness connector.
NOTE:
NOTE:The rain sensor module is also responsible for actuating the automatic headlamps.
  1. Verify the customer concern.
  1. Visually inspect for obvious signs of electrical (or mechanical) damage.

Visual Inspection

Mechanical Electrical
  • Check the adhesive pad between the rain sensor and the windshield for trapped air.
  • Clean wax residues from the windshield in the vicinity of the rain sensor.
  • Check the windshield for damage/cracks in the vicinity of the rain sensor.
  • Check that the rain sensor retaining frame is correctly attached to the windshield.
  • Check the wiper blades for residue-free wiping in the vicinity of the rain sensor.
  • Fuse(s)
  • Bulb(s)
  • Connector
  • Switch
  • Wiring loom
  1. Resolve any obvious causes or concerns found during the visual inspection before carrying out any further tests.
  1. If the concern is not visually evident, PERFORM a fault diagnosis on the generic electronic module (GEM) with WDS and RECTIFY any displayed faults in accordance with the displayed fault description. CHECK the operation of the system.
  1. On a vehicle without stored fault(s), continue according to the Symptom Chart and the corresponding symptom.
  1. Following checking or elimination of the fault(s) and after completion of operations, the fault memory in the generic electronic module (GEM) must be READ OUT and any stored faults must be DELETED. After road testing and CHECKING the system, READ OUT the fault memory again.
