Drive Away Release
The EPB module will initiate its 'Drive Away Release' function and automatically release the parking brake if the following conditions are detected:
- The engine is running.
- Drive, or reverse is selected.
- Positive throttle movement is detected.
The EPB module receives messages of gear selector position and throttle angle over the high speed CAN bus from the TCM (transmission control module) and the ECM (engine control module) respectively.
