Safety

When the engine reaches 5,400 rpm, the overspeed relay becomes energized. The power supply for the cruise control module safety circuit is interrupted which causes the module to open the ground path. Since the safety solenoid and the pump are no longer operating, the vacuum circuit is inoperative. Pressure on the brake or clutch pedal will have the same result.

The stop switch also sends information to the control module. The electronics open the ground path. The safety solenoid then vents the circuit.


NOTE: IT IS STILL POSSIBLE TO EXCEED THE MEMORIZED SPEED BY PRESSING THE ACCELERATOR. WHEN THE PEDAL IS RELEASED, THE VEHICLE RESUMES ITS REGULATED SPEED. THE RANGE OF OPERATION FOR MEMORIZATION OF A REGULATED SPEED IS APPROXIMATELY 48 KM/H (30 MPH) TO 129 KM/H (80 MPH).
