Circuit/System Description

The electronic brake control module (EBCM) receives serial data message inputs from the steering wheel position sensor identifying the position and direction of the steering wheel rotation.

Conditions for Running the DTC

* Ignition ON.

* Ignition voltage is greater than 10 volts.

* The vehicle speed is greater than 16 km/h (10 MPH).

Conditions for Setting the DTC

The calculated steering angle does not correlate with the steering wheel position sensor and the yaw rate sensor.

Actions Taken when the DTC Sets

* A driver information center message and/or a warning indicator may be displayed.

* The electronic brake control module disables the ABS, the stability control and the traction control for the duration of the ignition cycle.

Conditions for Clearing the DTC

* The condition for setting the DTC is no longer present.

* The electronic brake control module clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.

Diagnostic Aids

* The car should not pull in either direction causing the steering wheel to be OFF center while driving straight on a level surface.

* Improperly mounted or loose steering wheel position sensor.

* Confirm that all tires are of the proper size and that all are matching brands. Check and adjust all tires to the stated cold air pressure as identified on the tire placard. If a mis-sized or non-matching brand tire is present, inform the customer that in order for the vehicle stability enhanced system to function normally, tires need to be a uniform size and rolling diameter.

Circuit/System Verification

1. Ignition ON, verify that DTCs U1826, U1827, or C0292 are not set.

• If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.

2. Perform the steering angle sensor calibration procedure. Refer to Steering Angle Sensor Centering Procedures.

3. With a scan tool, clear the DTC.

4. Operate the vehicle within the conditions for running the DTC. Verify the DTC does not reset.

• If the DTC resets, replace the steering wheel position sensor.
