SOLENOID VALVE INSPECTION [SJ6A-EL]
CAUTION:
Water or foreign material entering the connector can cause poor connections or corrosion. Be sure that water or foreign material do not enter the connector when disconnecting it.
Do not damage the terminals.
Resistance inspection (On-vehicle)
1. Remove the battery cover.
2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [LF].)
3. Disconnect the solenoid valve connector.
4. Measure the resistance between the following terminals.
If there is any malfunction, inspect the coupler component.
Solenoid valve resistance (ATF temperature: 20 °C {68 °F})
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].)

Continuity Inspection (On-Vehicle Inspection)
CAUTION:
Water or foreign material entering the connector can cause a poor connection or corrosion. Be sure not to allow water or foreign material on the connector when disconnecting.
Do not damage the terminals.
1. Remove the battery cover.
2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [LF].)
3. Disconnect the solenoid valve connector.
4. 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].)
5. Connect the solenoid valve connector.
6. Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [LF].)
7. Install the battery cover.
