Cruise Control: Programming and Relearning
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"
