Volvo-Modelle, für die dieser Fehlercode gilt
Dieser Fehlercode hat je nach Modell, Modelljahr oder Motor unterschiedliche Bedeutungen. Wählen Sie die Bedeutung, die für Ihr Fahrzeug gilt.
Gilt für folgende Modelle:
7 ModelleS60 (2011–), S80 (2007–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
Was bedeutet der Fehlercode?
CEM monitors the reverse inhibit and the voltage on its signal cable. The signal cable is either broken or shorted to battery voltage, so reverse cannot be engaged. The inhibit may be switched off permanently if the fault persists.
Mögliche Ursachen
- Open circuit on the signal wire to the reverse inhibit
- The signal wire to the reverse inhibit is shorted to battery voltage
Was Sie tun können
- 1Check that the reverse inhibit fuses in the engine bay fuse box and in the CEM are intact
- 2Use a multimeter to check that the signal wire to the reverse inhibit has no break with the ignition in position II
- 3Use a multimeter to check that the signal wire has no contact with battery voltage
- 4Check the connectors on the signal wire for loose connections and corrosion
- 5With a diagnostic tool, clear the fault codes and start a new driving cycle. If the code returns straight away, the fault is active
- 6If no cause is found in the wiring, have a workshop check the relay and the CEM output
Symptome, die Sie bemerken können1
- Reverse cannot be engaged
Was der Fehler beeinflussen kann2
- The inhibit switches off permanently after 100 driving cycles in which the fault was detected
- Erasing the fault codes resets the output
