Hyundai Tucson: Automatic Transaxle Control System / Transaxle Control Module (TCM) Description and Operation

Hyundai Tucson (LM) 2010-2015 Service Manual / Automatic Transaxle System / Automatic Transaxle Control System / Transaxle Control Module (TCM) Description and Operation

Description

Transaxle Control Module (TCM) is the automatic transmission's brain. The module receives and processes signals from various sensors and implements a wide range of transmission 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 transmission failure or malfunction, TCM stores the fault information in memory so that the technician may reference the code and quickly repair the transmission.

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.
