TCC Brake Switch

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The TCC Brake switch sends a signal to the powertrain control module (PCM) when the brake pedal is depressed. The switch is normally open when the brake pedal is in the released position. When the brake pedal is depressed, the switch is closed. If the torque converter clutch (TCC) is engaged when the brake pedal is depressed, the PCM will disengage the TCC.
