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.
Circuit Description
Stepper Motor Cruise Control (SMCC) module sends cruise status input to Powertrain Control Module (PCM) to indicate when cruise control is engaged. PCM monitors cruise status signal while commanding cruise control to be disengaged by grounding cruise inhibit circuit.
Following will cause PCM to inhibit cruise control operation:
- Engine not running long enough for cruise control operation.
- Transaxle range inputs indicate Park, Neutral, Low or Reverse gear selected.
- Engine or vehicle speed too high or too low.
- ABS system is active for longer than 2 seconds.
- Vehicle acceleration or deceleration rate is too high.
Conditions for setting DTC:
- PCM commanding the SMCC module to inhibit cruise control operation.
- Cruise status input to PCM indicates that cruise is still active.
- Conditions present longer than one second.
