What does this fault code mean?
The left front door module powers the defroster element in the left door mirror. The control module has registered that the signal from the output is too high when the defroster is activated. The fault is caused by the signal cable to the defroster being short-circuited to supply voltage, and the mirror heating then does not work.
Possible causes

- 3Use a multimeter to check that the signal cable to the defroster has no contact with supply voltage
- 4Look for damage and chafing on the wiring at the left door mirror and check the connectors for oxidation
- 5Remedy as needed, then check that the heating works afterwards
