At each new ignition cycle, the brake control module (BCM) compares a value for the steering wheel angle from the steering wheel angle sensor with a calculated value. The diagnostic trouble code (DTC) is stored if the brake control module (BCM) registers that the deviation is too great.

The diagnostic trouble code (DTC) can be diagnosed at speeds above 10 km/h and when the steering wheel has been turned 10 degrees in either direction.
