SOLENOID VALVE INSPECTION [FN4A-EL]

Resistance Inspection (On-Vehicle Inspection)

Caution

• Water or foreign material entering the connector can cause a poor connection or corrosion. Be sure not to spill water or foreign material on the connector when disconnecting it.

1. Disconnect the negative battery cable.

2. Remove the battery, battery box and battery tray. (See BATTERY REMOVAL/INSTALLATION [L3, AJ].)

3. Remove the air cleaner cover. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3].)

4. Disconnect the transaxle connector.

Note

• When inspecting the pressure control solenoid, connect the ground connection to the ground terminal (terminal I) of the pressure control solenoid inside the solenoid valve connector.

5. Measure the resistance between the following terminals.

• If there is any malfunction, inspect the ground, then perform the operating inspection.

ATF temperature: -40-150 °C {-40-302 °F}

Terminal	Solenoid valve	Resistance (ohm)
A-GND	Shift solenoid A	1.0-4.2
C-GND	Shift solenoid B	1.0-4.2
G-GND	Shift solenoid C	1.0-4.2
B-GND	Shift solenoid D	10.9-26.2
F-GND	Shift solenoid E	10.9-26.2
D-I	Pressure control	2.4-7.3

6. Connect the transaxle connector.

7. Install the air cleaner cover. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3].)

8. Install the battery, battery box and battery tray. (See BATTERY REMOVAL/INSTALLATION [L3, AJ].)

9. Connect the negative battery cable.

Operating Inspection

Caution

• Water or foreign material entering the connector can cause a poor connection or corrosion. Be sure not to spill water or foreign material on the connector when disconnecting it.

1. Disconnect the negative battery cable.

2. Remove the battery, battery box and battery tray. (See BATTERY REMOVAL/INSTALLATION [L3, AJ].)

3. Remove the air cleaner cover. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3].)

4. Disconnect the transaxle connector.

Caution

• Do not apply battery positive voltage to terminals A, B, C, D, F and G for more than 3 s.

Note

• Because the operation sound of the valves is small, perform inspection in a quiet place.

5. Apply the battery positive voltage to transaxle connector terminals A, B, C, F or G and battery negative voltage to GND, and verify that operation sound is heard from the solenoid.

• If a "click" is not heard, inspect the transaxle wiring harness.

- If the transaxle wiring harness is normal, perform the resistance inspection (off-vehicle inspection).

- If there is any malfunction, repair or replace the transaxle wiring harness.

6. Apply the battery positive voltage to transaxle connector terminal D and battery negative voltage to the transaxle connector terminal I, and verify that operation sound is heard from solenoid.

• If a "click" is not heard, inspect the transaxle harness.

- If transaxle harness is normal, perform the resistance inspection (off-vehicle inspection).

- If there is any malfunction, repair or replace the transaxle harness.

Resistance Inspection (Off-Vehicle Inspection)

1. Remove the control valve body. (See SOLENOID VALVE REMOVAL/INSTALLATION [FN4A-EL].)

2. Measure the resistance of each solenoid valve individually.

• If there is any malfunction, replace the solenoid valve.

3. Install the control valve body. (See SOLENOID VALVE REMOVAL/INSTALLATION [FN4A-EL].)
