System overview
System overview |
The selector lever position sensor is connected to the manual shifting valve in the valve housing, which is also actuated by the selector lever.
The following shift-lock functions are provided in the selector lever housing: |
Shift-lock
Shift-lock means that the brake pedal must be depressed and the ignition key turned at least to position OFF before the selector lever can be moved from the P position. The system comprises 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 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 G41P, whereby the selector lever can be moved from the P position.
To disable the SHIFT-LOCK function in the event of power loss, proceed as follows:
1. |
Turn the ignition key to the OFF position.
|
2. |
Depress the oblong button at the side of the selector lever to release the SHIFT-LOCK function.

Anti-theft/Starter motor interlock function
When this function is operative, the ignition key must be inserted in the ignition switch and turned at least to the OFF position before it will be possible to move the selector lever out of position P.The interlock function consists of the ignition switch, a locking pin and a mechanical cable connecting these components.
When the selector lever is in position P and the ignition switch is in the LOCK position, the cable pulls the locking pin into a tooth space to lock the selector lever in position P.
Selector lever position catch
A locking button on the gear selection lever must be depressed before it will be possible to move the lever from positions P to R, D to M, M to L, N to R, and R to P.This function consists of a catch, a locking pin and a rod which connects these components. The locking pin blocks the lever in the different positions and when the catch is activated the selector lever is released from the locking segment and can then be moved to the desired position.
