Shift Lever Assembly: Operation: Notes

The Shift Lever Assembly consists of a printed circuit board, an opti-electronic switch for program selection recognition at the "W/S" program selector, contacts at the shift lever for recognizing the selected shift range, two plugs, and four light emitting diodes (LEDs) to illuminate the shift gate. The shift lever printed circuit board receives digital and analog input signals, controls various components and transfers information to various modules via the Controller Area Network (CAN) bus. The Shift Lever Assembly has input and output signals to the Data Link Connector. The Shift Lever Assembly receives input signals from the selector lever, the W/S switch, the upshift/downshift (+/-) Autostick switch, the shift gate illumination, the kickdown switch, and the brake lamp switch. The Shift Lever Assembly sends output signals to the reverse/park lock and the reverse lamps. A safety mechanism is built into the Shift Lever Assembly to prevent mechanical damage to the automatic transmission. The rear wheel speed is measured through the Controller Antilock Brake (CAB) and delivered to the Shift Lever Assembly. As a result, shifting the selector lever from Neutral to Reverse above approximately 8 km/h (5 MPH) is not allowed.

The ignition lock control cable attached to the Shift Lever Assembly prevents the driver from removing the ignition key if the selector lever is not in the Park position.
