Cruise Control System
(CCS) from m.y. 2002
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/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 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 on vehicles from m.y.
2002 should be performed using the VAS
5051 / 5052 Vehicle Diagnostic Testing
and Information System in operating
mode "Guided Fault Finding" or "Vehicle
Self-Diagnosis"
