CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM Pattern Select Switch Sport Mode Circuit

DESCRIPTION

The ECM memory contains the programs for the normal and sport shift patterns.

By following the programs corresponding to the signals from the pattern select switch assembly, the park/neutral position switch and other various sensors, the ECM switches the shift control solenoid valves on and off, and controls the transaxle gear ratio.
