What does this fault code mean?
The wires for signals A, B, IX and IY are intermittently short-circuited to each other. The fault has occurred at some point but may not be active right now. It can also come from an internal fault in the sensor control module.
Possible causes
- Signal wires for A, B, IX and IY short-circuited to each other
- Fault within the sensor control module
What you can do
- 1Clear the code and road test the car to see whether it returns
- 2Check the cable between the sensor control module and the sensor for chafing, pinching and loose clips
- 3Make sure the connectors at the control module and the sensor are firmly seated and clean
- 4With diagnostic equipment, follow signals A, B, IX and IY in live data while turning the wheel and see whether any of them jumps in value
- 5Stability control stays off while the fault is present, so have a workshop repair it promptly
