DIAGNOSTIC AIDS

CAUTION: Refer to SIR Caution in Service Precautions.

Disable the inflatable restraint steering wheel module when performing this diagnostic table. Refer to SIR Disabling and Enabling in Restraint Systems.

Perform the following in order to avoid misdiagnosis:
- Ensure that the following cruise control switches are not stuck in the engaged position:
- On/Off switch
- Set/Coast switch
- Resume/Accel switch
- Cancel switch
- Inspect for proper operation of the stop lamps.
- Rotate the steering wheel to both steering stops and activate each cruise control switch separately. With a scan tool, observe the associated cruise control switch parameter in the Body and Accessories Cruise Control data list. This will help eliminate the possibility of a internally open or shorted inflatable restraint steering wheel module coil.
- For an intermittent condition, refer to Diagnostic Aids for Circuit Testing and Wiring Repair Procedures. Component Tests and General Diagnostics
