Was bedeutet der Fehlercode?

The lane keeping function in the power steering control module (PSCM) is missing information that should come from the forward sensing module (FSM) or the brake control module (BCM), or the information is unreasonable. The cause may be poor contact, a break or interference in the wiring to the FSM or BCM, or in the CAN network.

Mögliche Ursachen

Poor contact at a connector, from resistance or oxidation
Brief open circuit or short circuit in the CAN cable between the PSCM and the FSM
Brief open circuit or short circuit in the CAN cable between the PSCM and the brake control module (BCM)
Open circuit or interference in the communication wiring between the PSCM and the FSM
Open circuit or interference in the communication wiring between the PSCM and the brake control module (BCM)
Disruption or brief open circuit on the controller area network (CAN)

Was Sie tun können

1Read off and clear the fault code, test drive and see whether it returns
2Check the connectors at the power steering control module, the FSM and the brake control module (BCM) for loose contacts
3Check that the wiring to the FSM and the BCM is not chafed or pinched
4Have a workshop with diagnostic equipment measure the communication to the FSM and the BCM
5Safety note: steering, lane keeping and brakes are safety systems, so have a workshop carry out the in-depth checks
