Kia Optima: Transaxle Control Module (TCM) Description and Operation
| Description |
Transaxle Control Module (TCM) is the automatic transaxle''s
brain. The module receives and processes signals from various sensors
and implements a wide range of transaxle controls to ensure optimal
driving conditions for the driver.
TCM is programmed for optimal response to any on-road
situation. In the event of a transaxle failure or malfunction, TCM
stores the fault information in memory so that the technician may
reference the code and quickly repair the transaxle.
