Was bedeutet der Fehlercode?

- 3Check the communication wire between the right camera module and the CEM for breaks, chafing and pinch damage
- 4Check the connectors in the camera module wire: loose or oxidised connectors should be cleaned and pressed in
- 5Use a multimeter to check that the wire is continuous between the connector ends and is not short-circuited to earth or voltage
