INSPECTION PROCEDURE

INSPECT PWR SWITCH (INTEGRATION CONTROL AND PANEL ASSEMBLY)

CHECK HARNESS AND CONNECTOR (INTEGRATION CONTROL AND PANEL ASSEMBLY - BODY GROUND)

CHECK HARNESS AND CONNECTOR (INTEGRATION CONTROL AND PANEL ASSEMBLY - ECM)

AUTOMATIC TRANSMISSION SYSTEM (for 1UR-FE) - Pattern Select Switch Power Mode Circuit

DESCRIPTION

The ECM memory contains the programs for the normal and power shift patterns and lock-up pattern.
By following the programs corresponding to the signals from the PWR 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.
