Hva betyr feilkoden?
The central electronic module (CEM) communicates with the remote receiver (RRX) when the ignition is switched on. The fault code is stored when that communication is incorrect, here because the LIN bus is shorted to voltage or earth. Tyre pressure monitoring may then show faults and the remote control may stop working.
Mulige årsaker
- LIN bus shorted to voltage or earth
- Internal fault in the remote receiver (RRX)
Hva du kan gjøre
- 1Check that the wiring to the remote receiver has no chafing or pinching, especially where the cable passes through the body
- 2With the ignition off, use a multimeter to check whether the LIN wire has contact with earth (the body) or voltage
- 3Check that the connectors are secure and dry
- 4Clear the fault code and road test to see whether it returns
- 5If the fault remains, have a workshop isolate the bus and find the faulty part with diagnostic equipment
Symptomer du kan merke2
- Tyre pressure monitoring warning lights and chimes do not show the correct status
- The remote control does not work
