Initial Inspection
Inspection and Verification1. Verify the customer concern.
2. Visually inspect for obvious signs of electrical damage.
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, connect the WDS or equivalent tester to the data link connector (DLC) and select the vehicle to be tested from the WDS or equivalent tester menu. If the WDS or equivalent tester does not communicate with the vehicle:
- check that the program card is correctly installed.
- check the connections to the vehicle.
- check the ignition switch position.
5. If the WDS or equivalent tester still does not communicate with the vehicle, refer to the WDS or equivalent tester operating manual.
