Component Transmission Inputs Monitor Introduction
Component Transmission Inputs Monitor Summary
The shift pattern and lock–up pattern are stored in the ECM.
The sensors and switches send signals of vehicle running conditions to the ECM.
The ECM determines whether the shift and lock–up operations should be turned on or off according to input
signals.
The ECM sends signals to each solenoid for shift and lock–up operation.
The input signals of sensors and switches are listed below:
Shift range signal by the shift positions switch
Transmission fluid temperature sensor signal by the transmission fluid temperature sensor
Vehicle speed signal by the speed sensor
Brake signal by the brake pedal depression (stop light switch is turned on)
Throttle valve opening angle signal by the throttle position sensor
Signal to adjust the transmission shift and lock up points by the pattern select switch
Engine coolant temperature signal by the engine coolant temperature sensor
Overdrive main switch ON/OFF switch
etc
