Terminal 50 (Engine Starting): Notes
Terminal 50 is actuated by pressing the start/stop button.
Engine start-up and the related terminal change are carried out as soon as the start/stop button is pressed for at least 50 milliseconds.
The following conditions are needed to complete the start sequence:
- Remote control is valid and locked (transponder authentication).
- Brake operation: the brake is either detected via the direct wiring of the brake-light switch or redundantly via the CAN signal from the DSC. An incorrect brake signal from a defective or disconnected brake-light switch is detected as a "plausibility fault" as soon as the brake pressure is greater than 10 bar. If one of the two signals is missing, a Check Control message is sent. The engine start-up is permitted when the start/stop button is pressed again.
- Selector lever of automatic transmission in position P and N. The position of the selector lever is detected via the direct P signal or via a CAN signal. The engine can be started when at least one of these signal is present.
- No start-repeat lock present (start-repeat lock is activated at an engine speed above 1000 RPM).
If these conditions are not met, the starter-motor disabling circuit is activated. The engine cannot be started.
