Hyundai Tucson: IMT Control Module (TCM)

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Intelligent Manual Transaxle (IMT) System / IMT Control Module (TCM)



The transaxle Control Module (TCM) is like the brain for the Intelligent Manual transaxle (IMT). It receives information from various sensors for a wide range of transaxle controls to provide an optimal driving environment for the driver. The TCM is programmed for optimal operation in all driving conditions. If the TCM malfunctions, store the failure information in memory and provide the error information to a mechanic for fast and accurate repair.
