Condition

The body sensor cluster stability sensor (BSC) indicates via a CAN message that an internal fault has occurred. The diagnostic trouble code (DTC) is stored when the brake control module (BCM) registers this.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute value

Hint: Brake system, abbreviations Brake System, Abbreviations
