Was bedeutet der Fehlercode?

The electric rear axle drive module (IEM) receives wheel speed values from the brake control module (BCM) over the CAN bus. Although the code is named sequence counter, it relates to wheel speed from the BCM being faulty or missing. The fault is only checked once the car is driven in gear D or R.

Mögliche Ursachen

Fault in the brake control module (BCM)
Software error in the electric rear axle drive module (IEM)

Was Sie tun können

1Read out, clear the code and road test in D or R to see whether it returns
2If you have diagnostic equipment: check in live data that the wheel speeds follow each other evenly during the road test
3Have a workshop check the brake control module (BCM) and whether new software is available for the IEM
4The braking system and the electric rear axle are safety critical; do not work on them yourself, have a workshop carry out the checks
