Hva betyr feilkoden?
The CEM hears nothing from the remote receiver (RRX) once the ignition comes on. The cause may be a cable break, a break in the power or earth supply to the receiver, or an internal fault in the receiver. The remote control will not work, and tyre pressure monitoring may stop functioning as well.
Mulige årsaker
- A break in the wire linking the CEM with the remote receiver module (RRX)
- Open circuit in the power supply to the remote receiver module (RRX)
- Open circuit in the earth cable to the remote receiver module (RRX)
- Internal fault in the remote receiver module (RRX)
Hva du kan gjøre
- 1Try locking and unlocking with several remote keys to rule out a faulty key
- 2If a low battery warning for the remote keys appears, replace the battery in the key
- 3Check that the connectors at the central electronic module (CEM) and the remote receiver (RRX) are secure and free from oxidation
- 4Follow the cable between the CEM and the remote receiver and check it is intact along its full length
- 5Check that the earth wire from the remote receiver to the body is intact
- 6Use a multimeter to confirm supply voltage at the remote receiver with the ignition on; if it is missing, have a workshop check the wiring
Symptomer du kan merke4
