DTC Descriptor

DTC C0253 Centering Error

Circuit/System Description

Steering angle centering is the process which the electronic brake control module (EBCM) calibrates the steering angle sensor so that it reads 0 when the steering wheel is centered. The data from the yaw rate sensor, lateral accelerometer and wheel speed is used under normal circumstances when the steering angle centering occurs after approximately 10 seconds of driving in a straight line on a fairly level surface at a speed greater than 7 mph/10 kph.

The usable output voltage range for the lateral accelerometer and yaw rate sensors is 0.25-4.75 volts. The scan tool will report zero lateral acceleration or yaw rate as 2.5 volts with no sensor bias present. The sensor bias compensates for sensor mounting alignment errors, electronic signal errors, temperature changes, and manufacturing differences.

Conditions for Running the DTC

The vehicle speed is greater than 40 km/h (25 mph).

Conditions for Setting the DTC

The vehicle has been driven for 10 minutes without completing steering angle centering.

Action Taken When the DTC Sets
    • The EBCM disables the vehicle stability enhancement system (VSES) for the duration of the ignition cycle.
    • The driver information center (DIC) displays the Service Stability System message.
    • The ABS/TCS remains functional.

Conditions for Clearing the DTC
    • The condition for the DTC is no longer present.
    • The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Diagnostic Aids

The following conditions can cause this concern:

    • Improper steering alignment.
    • Tire pull
    • Improperly mounted or loose yaw/lateral accelerometer sensor Internal yaw/lateral accelerometer failure.
    • EBCM internal failure.

Circuit/System Verification
  1. Clear code and operate vehicle within the conditions for setting the DTC. Verify DTC C0186, C0196, C0710 is not set.
    2. ⇒If DTC C0186, C0196, C0710 set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .
  2. Replace the EBCM.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
