Shiftlock



Shiftlock

It is only possible to shift out of the positions "P" or "N" after evaluation of the signals:
- Brake (brake light switch or brake light test switch)
- Road speed
- Engine speed
- Time

The selector lever is locked when no brake signal is detected with the engine running and the vehicle stationary. A time delay function of approx. 0.5 s is used for operation under winter conditions. The brake light switch is designed as a normally-opened contact referred to 12 V and the brake light test switch as a normally-open contact referred to ground. The shift lever is locked by way of a solenoid on the selector lever switch.
