What does this fault code mean?
The door module has flagged an internal fault, since a signal was not refreshed within a set time. The control module then goes into its limp-home mode, and the power window and door mirror control do not work.
Possible causes
- Internal fault in the door module
What you can do
- 1Read out and note the fault code, clear it, then run a test drive to see if it returns
- 2Bring the window to its upper limit by hand and start an initialization. From model year 2003 the window only lowers a short way before rising
- 3After initialization, check that the window raises and lowers normally with the switch
- 4If the fault remains, have a workshop replace the door module. A new module is delivered without software and must be programmed
