    Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.

    Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.

    The following additional checks may assist you in identifying a possible intermittent problem.

    Reconnect any disconnected components and harness connector.

    WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

    With the scan tool monitor active codes as you work through the following steps.

    WARNING: To avoid personal injury or death, maintain a safe distance from all airbags while performing the following steps.

    Wiggle the wiring harness and connectors of the related airbag circuit or component.

    If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.

    If only stored codes return continue the test until the problem area has been isolated.

    In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

    Are any ACTIVE DTCs present? 

    Yes 

    1. Select the appropriate symptom from Symptom List.

    No 

    1. No problem found at this time. Erase all codes before returning vehicle to customer.
