Transmission Control Switch (TCS)

Rotation of the TCS (Transmission Control Switch) to any of the five positions is sensed by the TCM (Transmission Control Module) via the HS (High Speed) CAN (Controller Area Network) Powertrain bus. The TCM then reacts according to the selected position. The TCS is a magnetic system using Hall effect sensors to determine the position of the switch.

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 TCS position is confirmed, the TCM outputs appropriate information on the HS CAN Powertrain bus which is received by the IC (Instrument Cluster) to display the gear selection information in the message center.

Refer to: Information and Message Center (Description and Operation).

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