Hva betyr feilkoden?
The rear seat entertainment control unit (RSE) checks the CAN signal between itself and the screens. The code is set when the voltage is too high. The cause is a CAN cable shorted to supply voltage.
Mulige årsaker
- CAN cable shorted to supply voltage
Hva du kan gjøre
- 1Check that the fuses for the rear seat entertainment are intact
- 2With the negative battery lead disconnected, use a multimeter to check that the CAN cable has no contact with voltage (plus)
- 3Look for chafing and pinched spots on the CAN cable and check that the connectors are fully seated
- 4With diagnostic equipment and the engine running, read the RSE parameters and see whether communication with the screens shows there
- 5If the fault remains, have a workshop with diagnostic equipment find where the cable touches voltage
Symptomer du kan merke1
- Rear seat entertainment does not work, has reduced function or works incorrectly
