Co oznacza ten kod błędu?

The engine control module has not received speed data from the brake control module, because the communication over the CAN network has been lost or disturbed. The code is set in the engine control module, and cruise control does not work while the signal is missing.

Możliwe przyczyny

Break in one or both CAN wires between the brake control module and the engine control module
Contact resistance in the CAN connections
One or both signal wires shorted to ground, supply voltage or each other
Damaged brake control module (BCM)
Damaged engine control module (ECM)

Co możesz zrobić

1Read the fault codes stored in the CEM and in other affected modules first, and remedy them
2Erase the fault code only once the faults are remedied, then test-drive
3With a multimeter you can check the CAN wires for breaks and for shorts to ground or supply voltage
4Since the fault concerns speed data from the brake control module, have a workshop check the braking system before you drive if the fault remains

Objawy, które możesz zauważyć1

Cruise control does not work at all

Na co może wpływać usterka2

Cruise control is switched off
In cars with an automatic gearbox, speed data from the gearbox module takes over instead
