The diagnostic trouble code (DTC) is stored if the brake control module (BCM) registers that the signal from the central electronic module (CEM), which contains information about the vehicle type, is invalid or has been absent for more than 27 seconds after the ignition is switched on.

The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.
