- Ensure that the following cruise control switches are not stuck in the engaged position:
- On/off switch
- - SET switch
- + RES switch
- With a scan tool, observe the associated cruise control switch parameter in the Powertrain Cruise Control Data list, while rotating the steering wheel to both steering stops and separately activating each cruise control switch. This will help eliminate the possibility of an internally shorted inflatable restraint steering wheel module coil.
