Transmission Control Switch
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The Transmission Control Switch (TCS) is installed in the top of the floor console. The TCS is secured with 4 screws and has an electrical connector for all electrical inputs and outputs.
Rotation of the TCS to any of the 5 positions, outputs a signal to the Transmission Control Module (TCM). The TCM senses the signals via the High Speed (HS) Controller Area Network (CAN) powertrain systems bus. The TCM then reacts according to the selected TCS position. The TCS uses Hall effect sensors to determine the position of the switch.
