Circuit Description

DTC will set if the PCM disengages the cruise. Normal vehicle operator induced commands such as brake on/off, cruise switch on/off, etc. will not set DTC. However, it is possible for vehicle operator to induce this DTC with abnormal driving maneuvers such as, shifting from D4 to Neutral or applying emergency brake while cruise is engaged.

PCM will disengage cruise and set DTC if the following conditions are met, ignition voltage is less than 10 volts or greater than 16 volts, vehicle acceleration is greater than 10 MPH per second or when traction control is active, decel is greater than 4 MPH per second, speed error is greater than 15 MPH for 10 seconds or 20 MPH instantaneously (caused if on steep hills), engine speed out of range, gear out of range (invalid gear ratio selection for cruise), or failure in PNP switch (A/T only).
