Transmission Control Switch
WARNING: This page is about a different variant/trim than selected.
The Transmission Control Switch (TCS) is installed in the top of the floor console. The TCS is secured with 4 screws and has 1 electrical connector for all electrical inputs and outputs.
Move of the TCS to any of the 5 positions outputs a signal to the Transmission Control Module (TCM). The TCM senses the signals through 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.
