System Testing
- If vehicle speed cannot be set or controlled, check for fault codes and initiate inspection mode (inspection codes). See RETRIEVING FAULT CODES and INITIATING INSPECTION MODE.
- If no fault codes are set and all inspection codes are okay, check components in the following order: main switch, cruise control unit, cruise brake switch, brakelight switch, clutch switch (M/T), cruise control switch, actuator and vehicle speed sensor. See COMPONENT TESTING.
