Cruise Control: Description and Operation

General Information

All cruise control system functions are controlled by the applicable Engine Control Module (ECM). The processing of electronic engine controls and cruise control functions are integrated in the ECM. Other than the cruise control switches on the steering column or multifunction steering wheel, the clutch and brake pedal switches and related wiring, there are no separate cruise control components to be serviced.

On vehicles so equipped, two supplementary CSS switches are integrated into the multi-function steering wheel.
