When Monitored: This diagnostic runs continuously when the following conditions are met:

? Ignition on. ? No under voltage DTCs. ? Driving straight. ? Speeds above 15 km/h (9 mph).

Set Conditions: ? Anti-lock Brake System (ABS) Module detects the Steering Angle Sensor (SAS) signal is above than ?15? of 0? while driving straight.

Default Actions: ? ABS is disabled.

Possible Causes STEERING WHEEL ALIGNMENT STEERING COLUMN OR INTERMEDIATE SHAFT IMPROPERLY INSTALLED OR DAMAGED STEERING ANGLE SENSOR (SAS) LOOSE STEERING COLUMN CONTROL MODULE (SCCM) ANTI-LOCK BRAKE SYSTEM (ABS) MODULE

1. CHECK FOR AN ACTIVE DTC

NOTE:

This DTC must be active for the results of this test to be valid.

1. Perform any Service Bulletins that may apply.

2. Turn the ignition on.

3. With the scan tool, read ABS DTCs and record on the repair order.

4. With the scan tool, read and record Environmental Data.

5. With the scan tool, erase ABS DTCs.

6. Test drive the vehicle straight with speeds above 15 km/h (9 mph).

7. Stop the vehicle.

8. Slowly turn the steering wheel from stop to stop.

9. With the scan tool, read ABS DTCs.

Is the DTC active?

Yes ? Go To 2

No ? Perform the ABS-INTERMITTENT CONDITION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure).

2. INSPECT THE WHEEL ALIGNMENT, STEERING COLUMN AND INTERMEDIATE SHAFT FOR INCORRECT INSTALLATION OR DAMAGE

NOTE:

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

1. Turn the ignition off.

2. Inspect the vehicle for proper wheel alignment.

3. Inspect the vehicle for damage causing tracking problems or steering wheel misalignment.

4. Inspect the steering column and intermediate shaft for damage.

Were any problems found?

Yes ? Repair as necessary.

? Perform the ABS VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure).

No ? Go To 3

3. CHECK THE STEERING ANGLE 1. Test drive the vehicle straight with speeds above 15 km/h (9 mph). 2. With scan tool, read the steering angle in the SCCM.

Is the Steering Angle reading within ?15? of 0??

Yes ? Replace the Anti-lock Brake System (ABS) Module in accordance with the Service Information. (Refer to 08 Electrical/8E - Electronic Control Modules/MODULE, Anti-Lock Brake System - Removal).

? Perform the ABS VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure).

No ? Go To 4

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

2. Verify that the Clockspring (SAS) is properly installed. 3. Inspect the vehicle for damage causing tracking problems or steering wheel misalignment. Is the Clockspring (SAS) properly installed? Yes ? Replace the Steering Column Control Module (SCCM) in accordance with the Service Information.

? Perform the ABS VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure).

No ? Repair as necessary. ? Perform the ABS VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Antilock Brake (ABS) - Standard Procedure).
