Was bedeutet der Fehlercode?
The driver door module waits for messages from the cameras on the left and right sides over LIN bus 2. The fault is stored when no signal is received, which can be caused by a break in the communication wire, a short circuit to ground or supply voltage, or a poor connection in the connectors.
Mögliche Ursachen
- Open circuit in the communication wire
- The communication wire is short-circuited to ground
- The communication wire is short-circuited to supply voltage
- Contact resistance or oxidation in the connections
- Open circuit in the connections
- Short circuit in the connections
