Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code information BCM-U030046

Condition





Note! The diagnostic trouble code only applies to vehicles equipped with DSTC.

The control modules continually transmit and receive information via the vehicle's CAN data network (Controller Area Network).
The diagnostic trouble code is generated if the brake control module (BCM) registers that there has been no signal from the central electronic module (CEM), which provides information on vehicle model, for more than 27 seconds.
The diagnostic trouble code can be diagnosed when the ignition is on.
