C0253

DTC C0253

Diagnostic Instructions

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



DTC Descriptor
DTC C0253
- Centering Error




Circuit Description

Steer angle centering is the process by which the electronic brake control module (EBCM) calibrates the steering sensor output so that the output reads zero when the steering wheel is centered.


Conditions for Running the DTC

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



Conditions for Setting the DTC

If the steering angle sensor controller area network (CAN) message or the EBCM indicates an uncentered sensor


Action Taken When the DTC Sets

If equipped, the following actions occur:

* The EBCM disables the ABS/traction control system (TCS)/vehicle stability enhancement system (VSES) and for the duration of the ignition cycle.
* A malfunction DTC will set.
* The ABS indicator turns ON.
* The Stability indicator turns ON.



Conditions for Clearing the DTC

* The condition for the DTC is no longer present and the DTC is cleared with a scan tool.
* The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.



Diagnostic Aids

Perform the steering angle sensor centering procedure.

Circuit/System Verification

1. With the scan tool perform the Steering Angle Sensor Centering procedure in EBCM VSES scan tool special functions.

• If DTC C0253 resets, test or replace the steering angle sensor.

2. Ignition ON, observe the ABS DTCS function in EBCM VSES scan tool data display.

• Does any DTC other than DTC C0253 reset. Refer to Diagnostic Trouble Code (DTC) List - Vehicle (Diagnostic Trouble Code Descriptions) .

3. Test drive the vehicle refer to Diagnostic Test Drive (Description of On-Board Diagnostics) .

• If DTC C0253 resets, test or replace the EBCM.




Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
