Diagnosis and Testing

General Equipment
Worldwide Diagnostic System (WDS)

Inspection and Verification

  1. Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical or electrical damage.
  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu.
  1. Retrieve the diagnostic trouble codes (DTCs) and refer to the DTC Charts.
