Was bedeutet der Fehlercode?
The engine control module (ECM) logs a communication fault between itself and the brake control module (BCM) and keeps the code there. Although the code is titled lost communication with the vehicle security control module, it concerns communication between the engine control module and the brake control module. The code has no separate troubleshooting.
