Scan Tool Testing and Procedures

2003 Volkswagen New Beetle (1C1) L4-2.0L (AVH)SECTION Scan Tool Testing and Procedures


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 Vehicle Diagnostic Testing and Information System in operating mode "Guided Fault Finding" or "Vehicle Self-Diagnosis".
