Control System
OUTLINEThe automatic transaxle senses vehicle operating conditions through various sensors. It always controls the optimum shift position and reduces shifting and lock-up shocks.
CONTROL SYSTEM
TCM FUNCTION
The function of the TCM is to:
^ Receive input signals sent from various switches and sensors.
^ Determine required line pressure, shifting point, lock-up operation, and engine brake operation.
^ Send required output signals to the respective solenoids.

CAN Communication
SYSTEM DESCRIPTION
Controller Area Network (CAN) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
