DTC C0253 Step 1 - 7:

Circuit Description
Steer angle centering is the process by which the 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 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/TCSNSES 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.

Test Description
The numbers refer to the step numbers on the diagnostic table.
2. Checks to see if other DTC is set.
3. Checks to see if steering angle sensor is centered.
