Instructions) provide an overview of each diagnostic category.



DTC Descriptors



DTC C028F 01



- Park Brake Solenoid Actuator Circuit Short to Battery



DTC C028F 02



- Park Brake Solenoid Actuator Circuit Short to Ground



DTC C028F 08



- Park Brake Solenoid Actuator Circuit Performance-Signal Invalid



Circuit/System Description



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. The parking brake control module contains an internal park brake solenoid actuator, and performs



diagnostics on the solenoid actuator circuitry to verify it is functioning properly



Conditions for Running the DTC



Ignition OFF, ACCESSORY, or RUN mode.



Conditions for Setting the DTC



The parking brake control module detects an internal park brake solenoid malfunction.



Action Taken When the DTC Sets



* The electric parking brake is disabled, one release allowed.



* A message and/or a warning indicator may be displayed.



Conditions for Clearing the DTC



* The parking brake control module clears the history DTC when a current DTC is not detected in 40 ignition cycles.



* The condition for the DTC is no longer present.
