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
| • |
