- Ensure that the following cruise control switches are not stuck in the engaged position:
- ON/OFF switch
- - Set switch
- + RES switch
- Cancel switch
- Inspect for proper operation of the stop lamps. Refer to Exterior Lighting Systems Description and Operation .
- Rotate the steering wheel to both steering stops while activating each cruise control switch separately. With a scan tool, observe the Cruise Control Switch parameters in the BCM. Ensure that each cruise control switch activated and that each displayed switch position in the Cruise Control Switch parameter match as the steering wheel is turned. This will help eliminate the possibility of an internally open or shorted inflatable restraint steering wheel module coil.
