Code B660, Cruise Control Not In Drive: Notes

Code B660 will set if cruise control is engaged and BCM detects that gear selector is in Park, Reverse or Neutral. This is done by the BCM based on ECM's input for Park and Neutral, and through circuit No. 24 feeding directly to BCM for Reverse gear status (HI on circuit No. 24 indicates Reverse). During time failure is present, BCM will disengage cruise control.
