What does this fault code mean?
The fault is intermittent: the power seat module (PSM) has on an earlier occasion found that the setting in memory position 2 does not match the calculated checksum. The fault is not present now. Memory function 2 then does not work.
Possible causes
- Memory position 2 is not stored
- Memory position 2 is stored incorrectly
What you can do
- 1Store the seat setting in memory position 2 again.
- 2Clear the fault code and use memory function 2 several times to see whether it returns.
- 3If the fault returns, have a workshop replace the power seat module (PSM), since the fault is then in the module.
