Scheme 1

Scheme 1: Clutch / Brake / Planetary Gear Function of Automatic Transaxle

Torq reduction sig (Torque reduction signal, ON / OFF)

ON: Signal which TCM require ECM to reduce output torque at shifting gear

OFF: Signal which TCM does not require ECM to reduce output torque

Engine torque (N.m)

Engine torque computed by duty pulse signal outputted from ECM.
