Selector Lever (Functional Descriptions)

Selector Lever

The selector lever is used to choose the desired transmission function and it has six mechanical positions.

The gear changes are triggered sequentially (one after the other). A gear or several gears can be skipped using rapid multiple touches.

In the gear shift gate, one press forwards (-) triggers a gear change (e.g. downshift from 5 to 4, 4 to 3, etc..). Pulling backwards (+) triggers a gear change (e.g. upshift from 1 to 2, 2 to 3 etc..).

In the direction of travel gate, moving the selector lever from neutral (N) in the direction of travel can shift to reverse (R).

Moving the selector lever towards C/M can change the operating modes from manual mode, M mode, to City mode, C mode, and vice versa.

Brief description of components
Seven Hall sensors are fitted in the selector lever block to identify the position. This records the selector-lever position without contact.

A spring-loaded mechanism holds the selector lever in each position: middle position, O position and reverse travel.

The selector lever is supplied with power by the load cutoff terminal (VA).

The selector-lever position is transferred through four analog cables and a digital cable to the SMG control module.

In the event of a fault, the transmission is permanently in the automatic mode.
