Circuit Description

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

The brake switch indicates brake pedal status to the powertrain control module (PCM). When the brake pedal is operated, the switch sends a signal to the PCM, the PCM then cancels the operation of the torque converter clutch (TCC) lock-up while braking is in progress. This prevents the engine from stalling.
