Torque Converter Clutch Solenoid Valve Test

Torque Converter Clutch Solenoid Valve Test





1. Connect the HDS to the DLC (A).
2. Select LOCKUP SOL TEST in MISCELLANEOUS TEST MENU on the HDS.
3. Carry out A/T LOCKUP SOL A test in LOCKUP SOL TEST MENU with the HDS.
4. Torque converter clutch solenoid valve test has finished if the test result is OK. If no sound is heard, go to step 5.





5. Disconnect torque converter clutch solenoid valve connector, and check the connector for good pin fit, corrosion, dirt, and oil. If the connector is OK, go to step 6. If the connector is not OK, repair the connector and do the test again.
6. Measure torque converter clutch solenoid valve resistance at the solenoid valve connector terminals.
Standard: 12 - 25 ohms
7. Replace torque converter clutch solenoid valve if no resistance is out of standard.
8. If the resistance is within the standard, connect the battery negative terminal to torque converter clutch solenoid valve connector terminal No. 2, and connect the battery positive terminal to the terminal No. 1.
9. Replace torque converter clutch solenoid valve if no clicking sound is heard.
10. If a clicking sound is heard, the solenoid is OK. Check the YEL wire from the PCM to the torque converter clutch solenoid valve for a short or open. If the wire is OK, substitute a known-good PCM and retest.
