What does this fault code mean?
The fault is intermittent: the control module has on an earlier occasion received no signal from motor 3 (M3+) for the seat rear edge. The fault is not present now. Seat rear edge height adjustment is then not possible.
Possible causes
- Open circuit in signal cable M3+
- Blown fuse (passenger compartment fuse 4)
What you can do
- 1Make sure passenger compartment fuse 4 is intact and sits properly in its holder.
- 2Move the wiring between the control module and motor 3 gently while the rear edge is adjusted. 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 motor 3 has no open circuit.
- 4If the fault remains, have a workshop check the motor and the control module.
