Brake Light Switch: Description and Operation

DESCRIPTION
The switch is mounted on the brake pedal mounting bracket under the instrument panel.

OPERATION
Vehicles equipped with the speed control option use a dual function stop lamp switch. The PCM monitors the state of the dual function stop lamp switch.

BRAKE SWITCH-PCM INPUT
When the brake switch is activated, the PCM receives an input indicating that the brakes are being applied. After receiving this input the PCM maintains idle speed to a scheduled RPM through control of the idle air control motor. The brake switch is mounted on the brake pedal support bracket.
