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.
• | The ignition is ON. |
• | The vehicle speed is greater than 40 km/h (25 mph). |
If the steering angle sensor CAN message or the EBCM indicates an uncentered sensor.
If equiped, the following actions occur:
• | The EBCM disables the ABS/TCS/VSES and for the duration of the ignition cycle. |
• | A malfunction DTC will set. |
• | The ABS indicator turns on. |
• | The TCS indicator turns on. |
• | The PCS indicator turns on. |
• | 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. |
Perform the steering angle sensor centering procedure.

1 | Did you perform the ABS Diagnostic System Check? | Go to Step 2 | |
Does the scan tool display any DTC other than DTC C0253? | Go to Step 3 | ||
Perform the steering angle sensor centering procedure. Refer to Steering Angle Sensor Centering . Did you successfully complete the centering procedure? | Go to Step 4 | Go to Step 5 | |
