Checking the connectors
- Ignition off
- Check the control module for the steering wheel angle sensor and the steering wheel module (SWM) connectors. Check for contact resistance and oxidation according to Contact resistance and oxidation
- Reinstall the components, reconnect the connectors etc.
- Ignition on
- Read off the current.
Turn the steering wheel to the limit position in both directions. The current should be between 11 and 30 mA.
If the current is OK, the cause of the fault was contact resistance or oxidation in the control module or in the steering wheel module (SWM) connector.
