Cruise Control: Description and Operation

Cruise Control System with Electronic Power Control

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/multifunction steering wheel, the
clutch and brake pedal switches and related wiring, there are no separate cruise control components to be serviced.

 As all electronic throttle control (EPC) 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. Always check DTC memory first before troubleshooting.

All CCS troubleshooting and OBD program functions are performed using the Vehicle Diagnosis, Testing & info. System (VAS 5051B ) (or other
VAS 505X class tester) in operating mode "Guided Fault Finding" or "Vehicle Self Diagnosis".
