Checking the power supply and ground for the steering wheel module (SWM)

NOTE:

Steering wheel angle sensor module (SAS) is located inside, and is supplied with power by, the steering wheel module (SWM). Only the steering wheel angle sensor module (SAS) communicates on the controller area network (CAN). The brake control module (BCM) will store a diagnostic trouble code (DTC) if the communication between the brake control module (BCM) and the steering wheel angle sensor module (SAS) has been interrupted. DSTC will not be activated after a fault in the system has been repaired until the vehicle reaches a speed of approximately 50 km/h.

Check that the fuse for the control module is intact.

Check the power supply and ground for the steering wheel module (SWM) as follows.

Remedy as necessary.
