Co oznacza ten kod błędu?
The fault code means that CEM receives no messages from the driver information module (DIM) on the CAN network. The fault may be an open circuit in the CAN wiring or an internal fault in the DIM. The start inhibitor may then stop working, and the function is switched off permanently after 100 operating cycles in which the fault is detected.
Możliwe przyczyny
- Open circuit in the CAN wiring between the control module and CEM
- Internal fault in the driver information module (DIM)
- If several fault codes are stored in CEM for communication faults with other modules, there may be a common fault in the CAN network
Co możesz zrobić
- 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 check that communication with the instrument cluster works
- 4Have a workshop check the CAN wires and the instrument cluster with diagnostic equipment. Do not replace the CEM without need
Objawy, które możesz zauważyć1
- Start inhibitor does not work
Na co może wpływać usterka2
- The function is switched off permanently after 100 operating cycles in which the fault was detected
- Erasing the fault codes resets the function
