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.
Cruise Control Inhibited
The PCM inhibits the cruise control operation when any of the following conditions exist:
- The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
- The engine RPM is low.
- The engine RPM is high.
- The vehicle speed is high.
- The system voltage is not between 9 volts-16 volts.
- The anti-lock brake system/traction control system is active for more than 2 seconds.
When the PCM detects a malfunction, or the cruise control criteria has not been met, the PCM grounds the cruise control inhibit signal circuit and the cruise control module detects a low signal voltage.
