AUTOMATIC TRANSMISSION SYSTEM (for 1VD-FTV) - Pattern Select Switch Power Mode Circuit


DESCRIPTION

The ECM memory contains the programs for the normal and power shift patterns and lock-up pattern.
By following the programs corresponding to the signals from the PWR switch, the park/neutral position switch and other various sensors, the ECM switches the solenoid valves on and off, and controls the transmission gear change and the lock-up clutch operation.
