IMPORTANT:
Repair any brake system related symptoms and DTCs before performing this diagnostic.
In order to avoid misdiagnosis, inspect for the following:
- Verify there are no DTCs set as current. If any DTCs are set as current, refer to Diagnostic Trouble Code (DTC) List - Vehicle and perform the appropriate diagnostics/repairs before proceeding with symptom based diagnostics.
- Inspect the cruise control switches for any sticking or binding conditions.
- Inspect for proper operation of the stop lamps. Refer to Exterior Lighting Systems Description and Operation .
- With the ignition ON, rotate the steering wheel to both steering stops while activating each cruise control switch separately. With a scan tool, observe all cruise control switch parameters in the BCM. Ensure that each cruise control switch activates and that each of the displayed switch position parameters match the currently activated switch, and do not read Error. This may aid in locating an intermittent fault within the inflatable restraint steering wheel module coil.
