Perform before beginning System Diagnosis
^ The Powertrain control Module will "Inhibit" Cruise Control when there is a malfunction in any of the Cruise Control Inhibit Criteria. The PCM will "Inhibit" Cruise Control when:
- The Engine is "off"
- An automatic transaxle is in "PARK" or "NEUTRAL"
- A manual transaxle is out of gear (in "NEUTRAL")
- There is high engine RPM (fuel cut-off)
- There is high vehicle speed (fuel cut-off)
- The PCM sets the following DTCs:
DTC 19 (CRANK SENSOR)
DTC 53 (UNDER/OVER BATTERY VOLTAGE)
DTC 65 (FUEL INJECTOR)
- A four speed automatic transaxle or Smart Cluster equipped car is in "REVERSE"
- A four speed automatic transaxle equipped car's PCM sets the following DTCs:
DTC 24 (VSS)
DTC 21 or 22 (TPS ACTIVE)
- The ETS (Enhanced Traction System) is active (4-Spd Auto & Pontiac only)
1. Check all cruise control inhibit criteria.
2. Check for Diagnostic Trouble Codes (DTCs). Refer to Powertrain Management. Powertrain Management
3. Check that Cruise Control Module Linkage is connected and moving freely.
4. Check Cruise Cable Adjustment.
5. Check Brake Switch for proper adjustment/alignment.
^ Make sure that Center High Mounted Stoplamp is working. If inoperative, Cruise Module will be disabled.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (Refer to "Diagnostic Aids/General Troubleshooting Procedures") Diagnostic Aids

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
