CONTROLLER AREA NETWORK (CAN)

CONTROLLER AREA NETWORK (CAN) Hyundai Tucson I

Previously, for different computers in the vehicle to share the same information, each signal required a different pin and wiring. However, with the introduction of a CAN system, only two lines are required to achieve the same function. The information is in digital format. This method does not use a integrated ECM.

Scheme 147: CONTROLLER AREA NETWORK (CAN)

Input signals to TCM through ' CAN communication'

Engine RPM, TPS signal
A/CON signal, Engine coolant temperature
Quantity of intake airflow, Vehicle speed
Shift holding signal (FTCS ON)

Output signals from TCM through ' CAN communication'

Request signal for torque reduction
ATF temperature, TCM type, TCM error or not
Damper clutch ON, OFF / Gear position
