    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.

    Removal     When replacing the TCM, the vehicle equipped with the immobilizer must be performed procedure as below. [In the case of installing used TCM] 1) Perform "TCM Neutral mode" procedure with GDS.
