Hva betyr feilkoden?
The central electronic module (CEM) communicates with the remote receiver (RRX) every time the ignition is switched on. The fault code is stored when that communication is incorrect. The remote control may then stop working and the tyre pressure monitoring may show faults.
Mulige årsaker
- Contact resistance, oxidation or loose connections in connectors or joints
- Internal fault in the remote receiver (RRX)
Hva du kan gjøre
- 1Check the connectors and wiring to the remote receiver for oxidation and loose connections, and gently move the wiring with the ignition on
- 2Test the remote control by locking and unlocking the car. If it still fails after the connectors are checked, the fault is probably still present
- 3With the ignition off, use a multimeter to check whether the wires to the remote receiver have contact with earth or voltage
- 4Clear the fault code and road test to see whether it returns
- 5If the fault remains, have a workshop check the communication and the remote receiver, since this needs diagnostic equipment
Symptomer du kan merke2
- The remote control does not work
- Tyre pressure monitoring warning lights and chimes do not show the correct status
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
