C0253

DTC C0253

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions provides an overview of each diagnostic category.



DTC Descriptor
DTC C0253 00
- Centering Error




Circuit/System Description

The usable output voltage range for the yaw rate sensor signal and lateral accelerometer sensor signal 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 steer angle centering.


Action Taken When the DTC Sets

* The EBCM disables the VSES for the duration of the ignition cycle.
* The driver information center (DIC) displays the TRAC/STABILITRAK OFF message.
* The antilock brake system (ABS) and traction control system (TCS) remain 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.
* Internal yaw and lateral acceleration sensor failure.
* EBCM internal failure.

Circuit/System Verification

1. With the scan tool perform the Steering Angle Sensor Calibration.
2. Operate the vehicle within the conditions for setting the DTC. Verify DTC C0186, C0196, C0253, or C0710 are not set.

• If DTC C0186, C0196, or C0710 are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .


• If only DTC C0253 set, replace the yaw and lateral acceleration sensor. If DTC C0253 sets again, replace the EBCM.




Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

* Vehicle Yaw Sensor with Vehicle Lateral Accelerometer Replacement (Service and Repair)
