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
•
Monitors the vehicle''s operating conditions to determine the optimal gear setting.
•
Performs a gear change if the current gear setting differs from the identified optimal gear setting.
•
Determines the need for Damper Clutch (D/C) activation and engages the clutch accordingly.
•
Calculates the optimal line pressure level by constantly monitoring the torque level and adjusts the pressure accordingly.
•
Diagnoses the automatic transaxle for faults and failures.

Removal
In case of removing the high pressure fuel pump, high
pressure fuel pipe, delivery pipe, and injector, there may be injury
caused by leakage of the high pressure fuel. So don’t do any repair
work right after engine stops.
