The parking brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The parking brake control module

also contains the logic for applying and releasing the parking brake when commanded by the park brake control switch. When the parking brake

control module receives a signal from the switch the internal circuit board temperature is checked to verify it is within operating range before the

control module performs the requested operation.
