Diagnostic Procedure

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.
  1. Disconnect the solenoid connector from the transaxle. Measure the resistance between terminal No. 3 and body ground. Resistance should be 11-13 ohms at 68°F (20°C). If resistance is not as specified, go to step  3. If measurement is within specification, go to next step.
  2. Connect the transmission harness connector. Disconnect the ECM connector. Measure the resistance between terminal DSL and El. Resistance should be 11-13 ohms at 68°F (20°C). If resistance is not as specified, repair or replace wiring harness and connector. If resistance is as specified, go to next step.
  3. Remove the transaxle oil pan. See LUBRICATION in appropriate AUTOMATIC article in TRANSMISSION SERVICING. Remove the shift solenoid valve DSL. Measure the resistance between the terminal DSL of shift solenoid valve and the solenoid body. Resistance should be 11-13 ohms at 68°F (20°C). If within specification, connect battery voltage to the positive lead of the solenoid connector, and ground the solenoid body. If the solenoid does not operate, replace the solenoid. If it does operate, repair or replace the wiring harness and connector.
