Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
System Diagnostics
The self-diagnostic capabilities of this system, if properly utilized, can simplify testing. Cruise control system is monitored by Powertrain Control Module (PCM).
If a problem is sensed with a monitored circuit, a Diagnostic Trouble Code (DTC) is stored in PCM. Once fault codes are known, refer to DIAGNOSTIC TROUBLE CODE (DTC) table to determine questionable circuit. Test circuits and repair or replace components as required. If problem is repaired or ceases to exist, PCM cancels that fault code after 50 ignition on/off cycles. To clear codes, refer to CLEARING DTC.
A specific fault code results from a particular system failure. It is NOT necessarily the reason for that failure. Fault code does not condemn a specific component. Fault code calls out a probable malfunction area.

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.
