Preliminary Inspection
- Check fuses, and replace as necessary. Visually inspect for broken or open wires. Check for a broken or partially broken wire inside insulation which could cause system malfunction but prove good in a continuity/voltage check with system disconnected.
- Check for Diagnostic Trouble Codes (DTCs). If any codes are present, see appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
- Ensure cruise control module assembly linkage is connected and moving freely. Ensure cruise control linkage is not binding. Check cruise control cable adjustment. See CRUISE CONTROL CABLE under ADJUSTMENTS. Ensure center high mounted brakelight is operating.
- Ensure any aftermarket electronic equipment is properly installed. Repair as necessary. If no problems are found, go to SYSTEM CHECK .
