What does this fault code mean?
The fault code means one of the signal cables to the seat motors, (M1 to M4 and MC) is short-circuited to supply voltage. The power memory seat then does not work at all, and the automatic front seat adjustment (memory) does not work either.
Possible causes
- Short to supply voltage on one of the signal cables for M1, M2, M3, M4 or MC
What you can do
- 1Check that the seat fuses are intact.
- 2Check that the connectors to the seat control module and the motors are firmly seated and free from corrosion.
- 3Use a multimeter to check that signal cables M1 to M4 and MC have no contact with supply voltage.
- 4If you have a diagnostic tool: activate the seat motors one at a time and see which one does not work.
- 5If the fault remains after these checks, have a workshop check the control module and the wiring.
Symptoms you may notice2
- The power memory seat does not work at all
- Automatic front seat adjustment (memory) does not work
