AUTOMATIC TRANSMISSION SYSTEM (for 1UR-FE) - 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+ (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.
