SOLENOID VALVE INSPECTION [SJ6A-EL]
CAUTION:
-
Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.
-
Do not damage the terminals.
1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)
2. Remove the selector lever knob. (See AUTOMATIC TRANSMISSION SHIFT MECHANISM REMOVAL/INSTALLATION.)
3. Remove the shift panel component. (See SHIFT PANEL REMOVAL/INSTALLATION.)
4. Remove the upper panel. (See UPPER PANEL REMOVAL/INSTALLATION.)
5. Remove the parking brake lever boot panel. (See PARKING BRAKE LEVER BOOT PANEL REMOVAL/INSTALLATION.)
6. Remove the rear console. (See REAR CONSOLE REMOVAL/INSTALLATION.)
7. Remove the front console panel. (See FRONT CONSOLE PANEL REMOVAL/INSTALLATION.)
8. Remove the front console component. (See FRONT CONSOLE REMOVAL/INSTALLATION.)
9. Disconnect the connector and wiring harness clip.
10. Place a clean rag behind the engine so that the engine does not contact the rear housing when it is tilted.
11. Remove the front crossmember under cover. (See FRONT CROSSMEMBER UNDER COVER REMOVAL/INSTALLATION.)
12. Disconnect the control rod from the selector lever component. (See AUTOMATIC TRANSMISSION SHIFT MECHANISM REMOVAL/INSTALLATION.)
13. Remove the tunnel member.
14. Disconnect the HO2S connector. (See HEATED OXYGEN SENSOR (HO2S) REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
15. Disconnect the TWC from the exhaust manifold (WU-TWC). (See EXHAUST SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
16. Suspend the TWC using a cable as shown in the figure.
17. Remove the power plant frame. (See POWER PLANT FRAME REMOVAL [M66M-D].) (See POWER PLANT FRAME INSTALLATION [M66M-D].)
18. Tilt the transmission while being careful not to allow parts on the back of the engine to contact the vehicle body.
19. Disconnect the solenoid valve connector.
20. Perform the resistance inspection (on-board).
a. Measure the resistance between the following terminals.
-
If there is any malfunction, inspect the coupler component.
-
If the coupler component is normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL [SJ6A-EL].) (See CONTROL VALVE BODY INSTALLATION [SJ6A-EL].)

21. Perform the continuity inspection (on-board).
a. Verify that there is no continuity between coupler component terminals C, D, E, F, G, H, I, J and GND.
-
If there is any malfunction, inspect the coupler component.
-
If the coupler component is normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL [SJ6A-EL].) (See CONTROL VALVE BODY INSTALLATION [SJ6A-EL].)
