Was bedeutet der Fehlercode?
The control modules in the car communicate over the CAN network. The rear electronic module (REM) has registered serious interference in that communication, which sets the code. The fault may be in the wiring, in a connector, or in a control module on the same part of the network.
Mögliche Ursachen
- Short-circuit in the CAN wiring
- Open circuit in one of the CAN wires
- Internal fault in the REM
- Internal fault in another control module on the same part of the CAN network
Was Sie tun können
- 1Read the codes in all control modules first and work through them in that order, then clear them and road test the car to see which ones come back
- 2Check whether there are codes for lost communication stored in the central electronic module (CEM), and deal with those first
- 3Disconnect the battery negative lead and use a multimeter to check that the CAN wires are not shorted to ground or voltage and have no open circuit
- 4Twist the wiring harness and wiggle the connectors where they are reachable during the test, and see whether anything changes
- 5Have a workshop with diagnostic equipment identify which control module is disturbing the network before any module is replaced
Symptome, die Sie bemerken können5
- The fuel gauge reads zero although fuel is in the tank
- Rear window heating does not work
- Folding headrest does not work
- Rear doors and the fuel filler cap do not lock or unlock
- On the S80 the trunk lid cannot be unlocked; on the V70, XC70 and XC90 the tailgate or trunk lid does not lock or unlock
Was der Fehler beeinflussen kann2
- The control module switches itself off (bus-off) and stays off until its power supply is cut
- When power is reconnected, the control module tries to communicate again
