PRINCIPLE OF OPERATION

For a detailed description of the wipers and washers systems and operation, refer to the relevant Description and Operation . Refer to See Wipers and Washers . .

INSPECTION AND VERIFICATION

CAUTIONDiagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.

Note. Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

  1. Verify the customer concern.
  2. Visually inspect for obvious signs of mechanical or electrical damage. VISUAL INSPECTION Mechanical Electrical Windshield and rear window for damage or contamination e.g. road film or general residue deposits Wiper blades, arms and linkage for wear, security, damage and freedom of movement Windshield/Rear window/Headlamp washer fluid level Washer pipes and jets for leaks, restrictions and damage Battery condition and state of charge Fusible links Fuses Relays Electrical connections Front and rear wiper motors Wiper switch Washer pumps Rain/light sensor Heated front washer jets Ignition switch Light switch Ambient air temperature sensor Central Junction Box (CJB) Battery Junction Box (BJB) Anti-Lock Braking System (ABS) module Automatic Temperature Control Module (ATCM) Instrument Cluster (IPC) module Controller Area Network (CAN) circuits
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
  4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
