TROUBLE SHOOTING
Note. Problems occurring with cruise control system can be caused by either electrical or mechanical components. Check each area separately during diagnosis. Begin diagnosis with simplest operation first, working in order up to increasingly more difficult operations.
PRELIMINARY INSPECTION
Before proceeding with any electrical trouble shooting, perform a mechanical inspection first. Check both ends of cruise control cable for proper connection to actuator and accelerator pedal assembly, ensure cruise control servo cable and accelerator pedal move freely and do not bind, check cruise control servo for bare, broken, or disconnected wires or connectors, check IG fuse (15-amp), located in fuse block on left side of instrument panel, check STOP fuse (15-amp), located in fuse block on left side of instrument panel, ensure ground connections are clean and tight, repair any DTCs before trouble shooting cruise control system, ensure speedometer and Vehicle Speed Sensor (VSS) are operating properly and check cruise control indicator bulb for open or shorted filament. If no obvious problems are found during inspection, proceed to SYSTEM TESTS .
