C0253
DTC C0253
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.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC C0253 Centering Error
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.
* A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
* Using 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.
