Brake Switch Feedback

Models equipped with cruise control systems may monitor the brake switch circuit and the cruise control release switch to determine when to engage and disengage cruise control. On vehicles equipped with a Torque Converter Clutch (TCC), the brake switch provides an input to the PCM to control the TCC solenoid located in the transaxle.
