Was bedeutet der Fehlercode?
The fault code means that CEM receives a signal from the driver information module (DIM) that it judges to be of lower quality than it accepts. The fault lies in the DIM, and the start inhibitor may stop working. The function is switched off permanently if the fault is detected over 100 operating cycles.
Mögliche Ursachen
- Internal fault in the driver information module (DIM)
Was Sie tun können
- 1Check that the fuses are intact and look up their positions in the handbook
- 2Test the relevant functions with buttons, controls or a road test to see whether the fault shows
- 3With a diagnostic tool, read the fault codes and note whether the fault returns after a restart
- 4Have a workshop trace the instrument cluster with diagnostic equipment. Do not replace the CEM unless testing shows it is damaged
