ELECTRONIC CONTROL SYSTEM
The electronic control system for the A340E automatic transmission provides extremely precise control of
the gear shift timing and lock±up timing in response to driving conditions as sensed by various sensors
located throughout the vehicle and in response to the engine's running condition.
At the same time, the ECM control reduces vehicle squat when the vehicle starts out and gear shift shock.
The electronic control system is also equipped with a self diagnosis system which diagnoses malfunctions
for the vehicle to continue functioning when a malfunction occurs.
CONSTRUCTION
The electronic control system can be broadly divided onto three groups; the sensors, ECM and actuators.

 Pattern Select Switch
 
 Selects the Power mode or the Normal mode for shift and
lock±up timing.
 
 Crankshaft Position Sensor and Camshaft Position
Sensor 
 Detects the engine speed.
 Park/Neutral Position Switch Detects the shift lever position.
 Stop Light Switch Detects if the brake pedal is depressed.
 Throttle Position Sensor Detects the throttle valve opening angle.
 O/D Main Switch Prevents up±shift to the O/D gear if the O/D switch is off.

This ECU prevents the transmission from shifting into O/D
and prohibits lock±up control when the vehicle's speed
drops below the cruise control set speed parameter.
 
 No.1 and No.2 Vehicle Speed Sensor.
 
 
Detects the vehicle speed. Ordinarily, transmission control
uses signals from the No.2 vehicle speed sensor, and the
No.1 vehicle speed sensor is used as a back±up.
