Electric Parking Brake Control Module

The electric parking brake module has an internal motor, apply actuator, release actuator, and temperature sensor. The electric parking brake module also contains the logic for applying and releasing the parking brake when commanded by the parking brake switch. When the electric parking brake module receives a signal from the switch, the internal circuit board temperature is checked to verify it is within operating range before the module performs the requested operation.

The electric parking brake module receives hard wired signals from the apply/release switch and communication enable. The electric parking brake module receives wheel speed sensor signals, engine torque, gear information, brake pedal signal, and etc. through GM-LAN.
