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.
Powertrain Control Module
Cruise Control Module (CCM) sends a signal to the Powertrain Control Module (PCM) through cruise engaged output terminal when cruise control is activated. The CCM cruise inhibit input terminal is a circuit used by the PCM to inhibit cruise control when conditions inconsistent with cruise operation are present. If the PCM determines that any of the cruise control inhibit conditions are present, the PCM requests that CCM suspend cruise control operation. The PCM accomplishes this request by opening the cruise inhibit output circuit. If the cruise engage output signal, sent by the CCM to the PCM, indicates that the cruise control is still engaged after the PCM has requested that cruise control disengage, the PCM sets a DTC. The PCM will inhibit cruise control under following conditions:
- Engine not running long enough for cruise control operation.
- Automatic transaxle is in Park, Reverse, Neutral or 1st gear.
- Manual transaxle is in Neutral.
- Engine speed is too high/low.
- Vehicle speed is too high/low.
- Anti-lock brake system/traction control system is active for greater than 2 seconds.
- Undercharged or overcharged battery condition exists.
- Vehicle acceleration/deceleration rate is too high.
