Volvo models this fault code applies to
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 signal wires for R1, R2, R3 and R4 from the sensor have short-circuited to each other, and the fault is intermittent: it may have occurred without being active now. The fault may also come from an internal fault in the sensor control module.
Possible causes
- Wiring for signals R1 to R4 has short-circuited to each other
- Fault within the sensor control module
What you can do
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check the wiring between the sensor control module and the sensor for an intermittent short circuit between the wires
- 3With diagnostic equipment, follow signals R1 to R4 in live data while turning the wheel and see whether any signal jumps in value
- 4Stability control stays off while the fault is present, so have a workshop repair it promptly if it returns
Symptoms you may notice3
- Anti-spin warning lamp lit
- Stability function not working
- Anti-spin function not working
What the fault can affect2
