C0051-2F-STEERING WHEEL POSITION SENSOR - SIGNAL ERRATIC

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the ignition on.

- Set Condition:
When the Anti-Lock Brake (ABS) Module detects too rapid of a change in the Steering Angle Sensor (SAS).





NOTE: Repair any Steering Angle Sensor (SAS) DTCs first before continuing with this diagnostic procedure. Testing and Inspection .

1. VERIFY THE DTC IS ACTIVE

NOTE: This DTC must be active for the results of this test to be valid. Repair all other Steering Angle Sensor codes before proceeding.

1. Perform any Technical Service Bulletins (TSBs) that may apply
2. Ignition on, engine not running.
3. With the scan tool, read and record DTCs.
4. Using the scan tool, read and record Environmental Data.
5. With the scan tool, erase DTCs.
6. With scan tool, graph the steering angle while slowly rotating steering wheel from lock to lock.
7. With the scan tool, read DTCs.

Is the graph displaying erratic signal behavior or is the DTC active at this time?

Yes

- Replace the Steering Column Control Module (SCCM). Steering Column Module - Removal.
- Perform the ABS VERIFICATION TEST. ABS Verification Test.

2. CHECK THE TERMINALS/CONNECTORS/WIRING HARNESS FOR DAMAGE

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 (SAS) installation is crucial for proper operation.

1. Inspect the Steering Angle Sensor (SAS).
2. Check all related wiring for bruised, chafed, pierced, or partially broken wires.
3. Check all related connectors for broken, bent, pushed out, or corroded terminals.
