Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- The supply wire to the interior lighting is shorted to voltage
Co możesz zrobić
- 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
Objawy, które możesz zauważyć2
- The interior lighting does not work
- The interior lighting does not switch off when the engine is running
Na co może wpływać usterka3
- The function switches off during the driving cycle in which the fault is detected
