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

    • 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.
