  4. CHECK THE CLOCKSPRING (SAS) 
    WARNING:

    To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

    NOTE:

    If available, check the vehicle repair history for collision damage.

    NOTE:

    Proper Clockspring (SAS) installation is crucial for proper operation.

    1. Turn the ignition off.
    2. Verify that the Clockspring (SAS) is properly installed.
    3. Inspect the vehicle for damage causing tracking problems or steering wheel misalignment.
