| DTC C0561 71: System Disabled Information
Stored-Invalid Serial Data Received |
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 module
will verify it has a valid signal from other modules before it
performs the requested operation.
