SOLENOID VALVE INSPECTION [JA5AX-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. (See Resistance Inspection (Off-Vehicle).)

Solenoid valve (ATF temperature: 20 °C {68 °F})

Terminals	Solenoid valve	Resistance (ohm)
A-J	2-4 brake solenoid valve	2.6-3.2
B-J	TCC solenoid valve	12.0-13.2
C-J	High clutch solenoid valve	2.6-3.2
D-J	Pressure control solenoid	2.6-3.2
E-J	Reduction timing solenoid valve	14-18
F-J	Shift solenoid C	14-18
G-J	Shift solenoid B	14-18
H-J	Neutral shift solenoid valve	14-18
I-J	Shift solenoid A	14-18

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. (See SOLENOID VALVE REMOVAL/INSTALLATION [JA5AX-EL].)

2. Measure the resistance of each solenoid valve individually.

• If not specified, replace the solenoid valve.

• If it is normal, replace the harness.
