Other than the cruise control switches on the steering column, the clutch and brake pedal switches and related wiring, there are no separate cruise control components to be serviced.

As the electronic throttle control operations are monitored by On Board Diagnostic (OBD), Diagnostic Trouble Codes (DTC) pertaining to engine electronics that are stored in DTC memory may be relevant to cruise control function.
