Ignition off
Check the connectors for the control module for the steering wheel angle sensor and for the steering wheel module (SWM). Check for Contact resistance and oxidation
Reinstall the components, reconnect the connectors etc.
Test drive the car. See Test driving
Ignition on
Read off diagnostic trouble codes (DTCs).
If the diagnostic trouble code (DTC) displays an intermittent status, the cause of the fault was probably contact resistance or oxidation in the connector for the control module for the steering wheel angle sensor or in the steering wheel module (SWM)

Other information:
- To disconnect the control module for the steering wheel angle sensor, see Contact reel/steering wheel angle sensor, replacing
- To disconnect the steering wheel module (SWM), see Steering wheel module (SWM), replacing
