Co oznacza ten kod błędu?

The code concerns the speed signal, which has too few transitions to be reliable. The fault may lie in the CAN communication, in the wiring between the control modules, or in the brake control module or the engine control module.

Możliwe przyczyny

Contact resistance in the CAN connections
Break in one or both CAN wires
One or both signal wires touching ground, supply voltage or the other wire
Damaged brake control module (BCM)
Damaged engine control module (ECM)

Co możesz zrobić

1If you have a diagnostic tool, read the fault codes in the brake control module and the engine control module, and remedy them first
2Check that the CAN connectors are secure and free from oxidation
3Look for chafing or pinch damage on the CAN wires and use a multimeter to check that they have no break
4The brake system is safety-critical: have a workshop check the brake control module. Do not work on the brake system yourself
5Clear the fault code once the fault has been remedied, then road test

Objawy, które możesz zauważyć1

The malfunction indicator lamp (MIL) lights up

Na co może wpływać usterka1

the brake module speed signal is replaced by a fixed value
