Diagnostic Test

  1. VERIFY THE DTC IS ACTIVE 
    NOTE:

    If DTC C2114-16, C2114-17 or U1003-88 are present, perform the diagnostics for these DTCs before continuing with this diagnostic procedure.

    1. Turn the ignition on.
    2. Using the scan tool, read and record ABS DTCs.
    3. Using the scan tool, read and record Environmental Data (EV Data).
    4. Using the scan tool, erase ABS DTCs.
    5. Cycle the ignition switch.
    6. Using the scan tool, read ABS DTCs.

      Is the DTC active at this time?

      Yes 

      • Go To  2

      No 

      • Perform the ABS-INTERMITTENT CONDITION diagnostic procedure. Refer to STANDARD PROCEDURE .
  2. INSPECT RELATED WIRING HARNESS, TERMINALS, AND CONNECTORS 
    1. Turn the ignition off to the lock position.
      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:

      Proper Steering Angle Sensor installation is crucial for proper operation.

    2. Visually inspect the related wiring harness. Look for any pinched, chafed, pierced, and partially broken wires.
    3. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, and corroded terminals.

      Were any problems found?
