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
Reinstall the components, reconnect the connectors etc.
Ignition on
Read off the status of steering wheel angle signal R2.
Turn the steering wheel in both directions and check that the value changes between ON and OFF.

If the value changes, the cause of the fault was contact resistance or oxidation in the control module or in the steering wheel angle sensor connector.
