The gear selector lever:
- Has seven positions: Park, Reverse, Neutral, Drive, Fourth, Third and Second.
- Operates the transmission selector shaft and rotary switch, in all positions (except Drive-to-fourth) by means of a Bowden cable.
- Passes driver gearshift requests to the transmission control module via the rotary switch.
The Drive-to-fourth switch:
- Detects when the gear selector lever is moved from Drive to Fourth.
- Is hard-wired to the transmission control module.
The Neutral position switch:
- Is hard-wired to the body processor module.
- Detects when the gear selector lever is moved to the Neutral position.
The Park position switch:
- Is hard-wired to the body processor module.
- Detects when the gear selector lever is moved to the Park position.
The gear selector module:
- Provides illumination of the gear selector surround, which is dimmable via a CAN signal from the instrument cluster.
- Provides red illumination, on the gear selector surround, of the gear selected, by CAN signals from the instrument cluster.
- Illuminates the security system Active LED on the gear selector surround, in response to an input from the body processor module.
- Is connected to the fascia harness via a 12-way connector.
The gear selector interlock solenoid:
- Prevents the gear selector lever from being moved from the Park position, unless the ignition switch is in position II, and the brake pedal is depressed.
- Is controlled by an input from the body processor module.
