Steering Position Signal Malfunction
The chassis or stability control module has received an invalid or missing steering position signal — often via the communication bus from the steering control module. ESP, lane assist and electric power steering may be limited.
Affected components
- Steering angle sensor
- Power steering module
- Esp control module
- Communication bus
Common causes
- High likelihood: Steering angle sensor or steering control module failed
- Medium likelihood: Communication bus fault between modules
- Low likelihood: Steering angle not calibrated
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
