Shift-lock function

When the shift-lock function is operative, the brake pedal must be depressed and the ignition switch turned to the ON position before the selector lever can be moved out of position P. This function is accomplished by means of a microswitch and a solenoid.

The microswitch is actuated by a cam on the selector lever and is closed only when the selector lever is in position P.

The solenoid blocks the selector lever's segment mechanically if it is not activated.

With the ignition switch in position ON and the brake pedal depressed (brake light switch closed), the solenoid is supplied with power via the microswitch (selector lever in position P). The solenoid is activated and the detent for the selector lever segment is released. The solenoid is grounded to grounding point G42, whereby the selector lever can be moved from the P position.
