Electronic Control Module

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Toyota RAV4, 2002 Toyota Highlander, 2002 Toyota Camry, 2002 Lexus RX 300, and 2001 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

ECM receives information from various input devices and uses this information to control shift solenoids and torque converter lock-up. ECM contains a self-diagnostic system, which will store a Diagnostic Trouble Code (DTC) if failure or problem exists in the electronic control system. To find location of ECM, see Fig 1-Fig 5 .

DTC can be retrieved to determine transaxle problem area. See RETRIEVING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM.
