Volvo models this fault code applies to
This fault code has different meanings depending on model, model year or engine. Select the meaning that applies to your car.
Applies to the following models:
5 modelsS60 (2001–2009), S80 (1999–2006), V70 (2000–2008), V70 XC / XC70 (2001–2007), XC90 (2003–)
What does this fault code mean?
The central module gets no communication from the right-hand camera module (RCM), which is part of the Blind Spot Indication System (BLIS). The LED on the right side therefore does not come on. The cause may be a missing voltage supply to the camera, a fault in the LIN bus wiring, or faulty behaviour in another control module.
Possible causes
- Problem with the voltage supply to the right camera module (RCM)
- Short circuit between the LIN wires
- Open circuit in one of the LIN wires
- Faulty behaviour in another control module on the network
What you can do
- 1Switch the ignition on and check that the right-side BLIS LED flashes three times when the system is activated
- 2With a multimeter, check that the signal wire to the right camera has no break and no contact with ground
- 3Also check that the connectors between the central module and the right camera are secure
- 4If the fault remains, have a workshop replace the right camera module (RCM)
Symptoms you may notice1
- The BLIS LED on the right side does not come on
