Checking The Power Supply And Ground For The Steering Wheel Angle Sensor Module (SAS)

Check the fuse for the steering wheel angle sensor module (SAS) in the fusebox in the passenger compartment.

NOTE:

If the fuse is blown, check the circuit after the fuse before replacing the fuse. Check for a short-circuit to ground. Then replace the fuse.

Check the cable between the fuse and the steering wheel angle sensor module (SAS). Check for an open-circuit.

Check the ground cable between the steering wheel angle sensor module (SAS) and the ground terminal. Check for contact resistance and oxidation. Check for an open-circuit.

Remedy as necessary.
