Hva betyr feilkoden?
The central electronic module (CEM) supplies the interior lighting. The code is set when the signal from the output is too high, which is caused by the supply wire being shorted to voltage.
Mulige årsaker
- The supply wire to the interior lighting is shorted to voltage
Hva du kan gjøre
- 1Read and clear the code and check whether the lamps work when they are switched on
- 2Check that the fuse for the interior lighting is intact
- 3Look for chafing on the supply wire to the interior lighting, especially if the cable may have been pinched
- 4Use a multimeter to see whether the supply wire has voltage with the ignition off
- 5If you have a diagnostic tool, activate the interior lighting and check that the lamps switch on and off as they should; otherwise have a workshop check the module output
Symptomer du kan merke2
