System Disabled Information Stored-Invalid Serial Data Received
| Circuit/System Description |
The electric parking brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The electric parking brake control module also contains the logic for applying and releasing the parking brake when commanded by the electric parking brake switch. When the electric 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 electric parking brake module will verify it has a valid signal from other modules before it performs the requested operation.
