Hyundai Ioniq (AE) 2017-2024 Service Manual / DCT(Dual Clutch Transmission) System / Dual Clutch Transmission Control System / DCT Control Module (TCM). Description and operation

The Transmission Control Module (TCM) is like the brain for the Dual Clutch Transmission (DCT). It receives information from various sensors for a wide range of transmission 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.
