AUTOMATIC TRANSMISSION 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 satellite switch set and other various sensors, the ECM switches the solenoid valves on and off, and controls the transmission gear ratio.
