Code C028F Description

The hand brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The hand brake control module also contains the logic for applying and releasing the hand brake when commanded by the hand brake control switch. When the hand 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. The hand brake control module contains an internal hand brake solenoid actuator, and performs diagnostics on the solenoid actuator circuitry to verify it is functioning properly
