What does this fault code mean?
The fault is intermittent: the control module has on an earlier occasion received no signal from motor 1 for front-rear adjustment (M1+). The fault is not present now. Front-rear seat adjustment then does not work.
Possible causes
- Open circuit in signal cable M1+
- Blown fuse (passenger compartment fuse 4)
What you can do
- 1Check that passenger compartment fuse 4 is intact and sits firmly in its holder.
- 2Move the wiring between the seat control module and the motor gently while you run the front-rear adjustment. If the adjustment stops or the fault code returns, the wiring is suspect.
- 3Use a multimeter to check that the wiring between the control module and the motor has no open circuit.
- 4If the fault remains, have a workshop check the motor and the control module.
