Solenoid Valve Inspection

SOLENOID VALVE INSPECTION [JA5A-EL]
Resistance Inspection (On-Vehicle)





1. Disconnect the negative battery cable.
2. Disconnect the terminal component No.1 connector.





3. Measure the resistance between the following terminals.
^ If not as specified, inspect each solenoid valve.





ATF temperature: 20°C (68°F)
4. Connect the terminal component No. 1 connector.
5. Connect the negative battery cable.

Operating Inspection (On-Vehicle)





1. Disconnect the terminal component No.1 connector.

Caution: Do not apply battery positive voltage to terminals for more than three seconds.

Note: Because the operation sound of the valves is small, inspect in a quiet place.

2. Apply battery positive voltage to terminals A, B, C, D, E, F, G, H, I and battery negative voltage to GND, and verify that operating sound is heard from solenoid.
^ If the "click" is not heard, inspect the transaxle harness.
^ If the transaxle harness is okay, perform the resistance inspection (off-vehicle inspection).
^ If there is a problem, repair or replace the transaxle harness.
3. Connect the terminal component No.1 connector.

Resistance Inspection (Off-Vehicle)
1. Remove each solenoid valve.
2. Measure the resistance of each solenoid valve individually.
^ If not specified, replace the solenoid valve.
^ If it is normal, replace the harness.
