Hyundai Tucson: DCT (Dual Clutch Transmission) System (SBC) - Description
Description
The Dual Clutch Transmission (DCT) control system measures required data to identify the state of the control target and computes the appropriate compensation value if adjustment is necessary. The actuator is controlled according to the computed compensation value to obtain desired output.
If transmission or driving-performance-related failure is detected, first perform self-diagnosis and basic transmission inspection (oil check).
Then use the diagnostic tool to inspect the transmission control system components.
Operation principle
Description
Function
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.

Inspection
Inspecting TCM ground circuit: Measure the resistance between the TCM
and chassis ground.
(Check the terminal connected to the chassis ground while using the back of
the harness connector as the base point for TCM.)
