Inspection and Testing

  1. VERIFY the customer concern.
  1. Visually CHECK for any obvious mechanical or electrical damage.
NOTE:
NOTE:Ensure correct locking of wiring harness connector.

Visual Inspection

Electrical
Fuses.
Wiring harness.
Electrical connectors.
  1. RECTIFY any obvious causes for a concern found during the visual inspection before performing any further tests. CHECK the operation of the system.
  1. If the concern persists after the visual inspection, PERFORM a fault diagnosis with the diagnostic unit, RECTIFY any displayed faults in accordance with the displayed fault description and then DELETE the displayed fault(s). CHECK the operation of the system.
  1. For vehicles with no stored fault(s), PROCEED in accordance with the Symptom Chart according to the fault symptom.
  1. Following checking or elimination of the fault and after completion of operations, the fault memories of all vehicle modules must be READ OUT and any stored faults must be DELETED. READ OUT all fault memories again following a road test.
