DTC P0724 Brake Switch "B" Circuit High: Description

WARNING: This page is about a different variant/trim than selected.

The purpose of this circuit is to prevent the engine from stalling when brakes are suddenly applied while driving in lock-up condition.

When the brake pedal is depressed, the stop light switch sends a signal to the ECM. Then the ECM cancels the operation of the lock-up clutch while braking is in progress.
