Was bedeutet der Fehlercode?

The engine control module (ECM) compares the vehicle speed reported by the brake control module (BCM) with engine speed when fuel supply is cut, for example during engine braking. If the speed appears too low for a longer time, the code is set and the speedometer may show a wrong value.

Mögliche Ursachen

Wrong vehicle speed reading from the brake control module (BCM)
Dirt on the wheel speed sensors, which makes the speed signal too low

Was Sie tun können

1Check that the wheel sensors are clean and that no debris is stuck to them, since dirt can make the speed signal too low
2Read and fix the codes in the brake control module (BCM) first, since the speed signal comes from there
3If you have a diagnostic tool, compare the speed value in live data with the speedometer during a test drive and see whether it follows the car's speed
4The brake control module (BCM) is part of the braking system: do not work on it or its wiring yourself. Have a workshop check it if the fault remains
5Clear the code only once the cause is fixed, then road test to see whether it returns

Symptome, die Sie bemerken können2

The environment lamp lights up
The speedometer shows a wrong value

Was der Fehler beeinflussen kann2

On cars with a manual gearbox, the speed signal is set to a default value
On cars with an automatic gearbox, a secondary speed signal from the transmission control module (TCM) is used instead
