What does this fault code mean?
The right power seat control module (PSR) registers that the controls M4+ and M4-, which adjust the angle of the seat, are activated at the same time. This is an invalid combination, and adjustment of the seat's front edge does not work. The cause may be incorrect use of the control panel, a damaged panel or a damaged control module.
Possible causes
- Incorrect use of the control panel
- Damaged control panel
- Damaged right power seat control module (PSR)
What you can do
- 1Press only one front edge control at a time and check that the seat moves in the right direction
- 2Press the front edge controls in separately and release them; they should spring back freely
- 3Check that the control panel is firmly fitted and not damaged or damp
- 4If you have diagnostic equipment, read the control status in live data and check that only one direction shows as activated at a time
- 5Clear the code after the checks and road test the car. If it returns although the controls work, have a workshop check the seat control module
