SOLENOID VALVE INSPECTION (PRIMARY CONTROL VALVE BODY) [FS5A-EL]

id051721807700

## Resistance Inspection (On-Vehicle Inspection)

  Caution

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

1. Disconnect the negative battery cable.

2. Remove the air cleaner component. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L3].)

3. Disconnect the transaxle connector (primary).

  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.

4. Measure the resistance between the following terminals.

  • If not as specified, inspect the ground, then perform the operating inspection.

Primary control valve body (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 solenoid A | 2.4-7.3

5. Connect the transaxle connector (primary).

6. Install the air cleaner component. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L3].)

7. Connect the negative battery cable.

## Operating Inspection

1. Disconnect the transaxle connector (primary).

  Caution

  • Do not apply battery position voltage to terminals A, B, C, D, F and G for more than three seconds.

  Note

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

2. Apply battery positive voltage to terminals A,B,C, F or G 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. Apply battery positive voltage to terminal D and battery negative voltage to terminal I, and verify that operating sound is heard from solenoid.

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

  - If transaxle harness is okay, perform the resistance inspection (off-vehicle inspection)
  - If there is a problem, repair or replace the transaxle harness.

## Resistance Inspection (Off-Vehicle Inspection)

1. Disconnect the negative battery cable.

2. Remove the solenoid valve(s). (See SOLENOID VALVE REMOVAL/INSTALLATION (PRIMARY CONTROL VALVE BODY) [FS5A-EL].)

3. Measure the resistance of each solenoid valve individually.

  • If not as specified, replace the solenoid valve.

4. Install the solenoid valve(s). (See SOLENOID VALVE REMOVAL/INSTALLATION (PRIMARY CONTROL VALVE BODY) [FS5A-EL].)

5. Connect the negative battery cable.
