Information on Electronic Brake Control Module Set DTCs C0252/C0460 and Power Steering Control Module Set DTCs C056E/C0r60/C0545

If any of the following DTCs are found (current or history), the following procedure should be performed before any components are replaced.

Important: 

After the software has been updated, perform the following checks using the Tech 2®:

1. Verify under the diagnostic menu that the STEERING WHEEL ANGLE reads zero when the wheels are pointed straight ahead.
2. Verify under the diagnostic menu that the STEERING WHEEL ANGLE SENSOR CALIBRATION STATUS reads calibrated.
3. Verify under the diagnostic menu that the STEERING WHEEL ANGLE VALIDITY reads valid.

If any of the above checks are incorrect, perform the following procedure using the Tech 2®:

1. Clear all the codes.
2. Perform the "Steering Pos./Torque Sensor Cal" in the power steering control module. During the calibration procedure steering assist will not function. Raising the vehicle off the ground will reduce the steering loads and make it easier to perform the procedure.
3. Perform the "Steering Pos. Sensor Calibration" in the electronic brake control module.
4. Verify that there are no DTCs.
5. Test drive the vehicle.

Note: The "SERVICE STABILITRAK" message may stay on after the codes have been cleared. It may be necessary to drive the vehicle before the message turns off. This allows the EBCM to verify that no malfunctions exist before turning off the message.
