Circuit Description

The cruise control module sends cruise status input to 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.

DTC will set when PCM is commanding the cruise control module to inhibit cruise control operation, cruise status input to PCM indicates that cruise is still active and conditions are present longer than one second.
