AUTOMATIC TRANSMISSION SYSTEM Pattern Select Switch Sport Mode Circuit

DESCRIPTION

The ECM memory contains the programs for the normal and sport shift patterns and lock-up pattern.

By following the programs corresponding to the signals from the SPORT S/S+ switch (integration control and panel assembly), 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.
