Circuit Description
PCM has the ability to disable cruise control if conditions are detected which would make cruise control operation undesirable. The 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 and 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 all these conditions are present for longer than one second.
