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.
Functions
