Trouble Shooting

Verify customers concern by operating cruise control system. Ensure horn, brakelights, and speedometer are functioning properly. Inspect cruise control servo/actuator and throttle linkage for smooth operation. Check for faulty fuses, loose or corroded connections, damaged wiring harness, damaged switches, damaged or binding servo/actuator cable and incorrect servo/actuator cable adjustment. If any cruise control systems, electrical or mechanical component is found faulty, repair, replace or adjust as necessary. If fault is not visually evident and vehicle is equipped with an electronic instrument cluster, perform self-diagnostics. See SELF-DIAGNOSTIC SYSTEM . If fault is not visually evident and vehicle is equipped with an analog instrument cluster, repair by symptom. See SYMPTOM INDEX  table under SYSTEM TESTS.
