- Open circuit
- Defective control module
What you can do

- 3Check the wiring between the steering wheel angle sensor and the control module for breaks, chafing or pinching
- 4If you have a diagnostic tool: follow the R1 angle signal in live data while turning the wheel slowly, and check that the value follows the wheel without jumps
- 5Stability control is off while the fault is present, so have a workshop repair it promptly if it returns
