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