SOLENOID VALVE INSPECTION [JA5AX-EL]

id051705801900

## 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.

Pressure control solenoid, 2-4 brake solenoid valve, and high clutch solenoid valve

  Resistance: 2.6-3.2 ohms (20 °C {68 °F})

Shift solenoid A, B, C, neutral shift solenoid valve, and reduction timing solenoid valve

  Resistance: 14-18 ohms (20 °C {68 °F})

TCC solenoid valve

  Resistance: 12-13.2 ohms (20 °C {68 °F})

3. Install each solenoid valve. (See SOLENOID VALVE REMOVAL/INSTALLATION [JA5AX-EL].)
