Stop Light Switch Circuit

STOP LIGHT SIGNAL CIRCUIT

CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling when the brakes are suddenly applied while driving in (torque converter) lock-up condition.
When the brake pedal is operated, this switch sends a signal to the ECM. Then the ECM cancels operation of the lock-up clutch while braking is in progress.
