Ignition ON.

Clear the DTCs.

Using the scan tool, perform the Heated Steering Wheel Module (HSWM) self-test.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new Heated Steering Wheel Module (HSWM). REFER to Heated Steering Wheel Module (HSWM) .
No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
