Hyundai Sonata LF: Dual Clutch Transmission Control System / Description and Operation
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.
