Selector Lever Switches
The park, reverse, neutral and drive switch is located on the left-hand side of the selector lever, secured to the base plate with two screws. The switch is connected to the main harness by a ten-pin connector. The park, reverse, neutral, drive and manual switch has four proximity sensors that correspond to the four selector lever positions. Two further proximity sensors correspond to the manual +/- positions. The selector lever has two targets, upper and lower. The upper target is aligned with the park, reverse, neutral, drive and manual sensors and the lower target aligns with the +/- sensors.
When the selector lever is moved to the manual/sport position, the upper target moves away from the drive proximity sensor. The GIU senses this and puts the transmission into manual/sport mode. The transmission will operate in sport mode until the GIU senses that either the + or the - proximity sensor is operated, the GIU will then operate the transmission in manual mode.
