Pattern Select Switch Circuit

CIRCUIT DESCRIPTION
The ECM memory contains the shift programs for the NORMAL and POWER patterns, 2 position and L position and the lock-up patterns. Following the programs corresponding to the signals from the pattern select switch, the park/neutral position switch and other various sensors the ECM switches the solenoid valves ON and OFF, thereby controlling the transmission gear change and the lock-up clutch operation.
