JAGUARDRIVE Selector

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XFR, 2015 Jaguar XF, 2014 Jaguar XFR, 2014 Jaguar XF, and 2013 Jaguar XFR. However, it is still accessible from the selected car via links, so may be relevant.

Rotation of the JaguarDrive selector to any of the five positions is sensed by the TCM (transmission control module) via the high speed CAN bus. A LIN bus connection is also provided, but is only used in the event of a CAN bus failure as a back-up. The TCM then reacts according to the selected position. The JaguarDrive selector is a magnetic system using Hall effect sensors to determine the position of the selector.

The S (sport) position selection allows the TCM to operate the transmission using the semi-automatic Jaguar sequential shift. Gear selections are sensed by the TCM when the driver operates the steering wheel paddle switches. Once the JaguarDrive selector position is confirmed, the TCM outputs appropriate information on the high speed CAN bus which is received by the instrument cluster to display the gear selection information in the message center. Refer to: Information and Message Center (413-08 Information and Message Center, Description and Operation).

The paddles can also be used on a temporary basis when the JaguarDrive selector is in the D (drive) position to override the automatic gear selection if required.

The Jaguardrive selector is a rotary selector installed in the top of the JaguarDrive selector module. The JaguarDrive selector module is located in the floor console and controls the vehicle optimization functions on the vehicle. For additional information, refer to: Ride and Handling Optimization (204-06 Ride and Handling Optimization, Description and Operation).

The TCM allows the transmission to be operated as a conventional automatic unit by selecting P, R, N, D on the JaguarDrive selector.

Rotation of the JaguarDrive selector allows the selection of P, R, N and D. By depressing the JaguarDrive selector and rotating clockwise from the D position, S mode can be selected. The JaguarDrive selector is fully electronic rotary transmission selector with no mechanical connection to the transmission.

The JaguarDrive selector rises from the JaguarDrive selector module once the engine is running. When the engine is stopped with the JaguarDrive selector in any position other than N, it retracts into the JaguarDrive selector module again. If the selector is in position N when the engine is stopped, it remains in the raised position for up to 10 minutes, for use in a drive through car wash for example. After 10 minutes the selector automatically retracts into the JaguarDrive selector module. The selector also retracts if P is selected within the 10 minute period.

If the JaguarDrive selector does not rise from the console when the engine is started, but electrical power is supplied to the selector, the retracted selector can still be rotated to make selections. If electrical power to the JaguarDrive selector is lost, the selector will not rise from the console when the engine is started and the retracted selector will not rotate.

The JaguarDrive selector contains an internal interlock solenoid to prevent the selector from being rotated when the engine is not running.

The engine can be stopped with the JaguarDrive selector in any position. Once the engine is stopped the selector will automatically reset to the P position and the transmission park lock will be engaged, except if the selector is moved to the N position when the engine is stopped.
