Brake Switch (Cruise Control): Description and Operation



Brake Pedal Position Switches

Vehicles with 2.5L, 3.0L or diesel engine
If the brake pedal is operated when the speed control system is active, the ECM will receive a signal from the brake pedal position primary and secondary switches. This will put the system into STANDBY mode and allow the vehicle to return to a speed demanded by the throttle pedal position.

The brake pedal position primary switch is also used to operate the stop lamps.
