Gjelder følgende modeller:
5 modellerS60 (2001–2009), S80 (1999–2006), V70 (2000–2008), V70 XC / XC70 (2001–2007), XC90 (2003–)
Hva betyr feilkoden?
The data communication wire between the CEM and the antenna unit around the ignition switch gives too low a signal. The cause may be a break in the +15 supply to the ignition switch, a break in the data communication or an earth fault. The fault is intermittent, so it may have occurred earlier without being active now.
Mulige årsaker
- Open circuit in the +15 supply
- Open circuit in the data communication wire
- Earth fault in the data communication wire
Hva du kan gjøre
- 1With the ignition off, check the earth lead of the antenna unit for loose connections and corrosion
- 2With the ignition on, check that the supply to the ignition switch is present, for example by checking the fuse
- 3Check the signal wire for chafing and loose connections, and check the connectors at the CEM and the antenna unit for corrosion
- 4Use a multimeter to check that the data communication wire has no break and no contact with ground (the body), testing one wire at a time
- 5If the fault returns and the wires are intact, a workshop should investigate the antenna unit
Symptomer du kan merke2
- Engine will not start
- Starter motor does not work
