Solenoid Valve Inspection (Secondary Control Valve Body)

SOLENOID VALVE INSPECTION (SECONDARY CONTROL VALVE BODY) [FS5A-EL]
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. Remove the battery duct and battery cover.
2. Disconnect the negative battery cable.
3. Remove the battery, battery box and battery tray.





4. Disconnect the transaxle connector (secondary).

Note:
^ When inspecting the pressure control solenoid, connect the ground connection to the ground terminal (terminal 1) of the pressure control solenoid inside the solenoid valve connector.





5. Measure the resistance between the following terminals.
^ If not as specified, inspect the ground, then perform the operating inspection.

Secondary control valve body (ATF temperature: -40-150°C (-40-302°F))





6. Connect the transaxle connector (secondary).
7. Install the battery, battery box and battery tray.
8. Connect the negative battery cable.
9. Install the battery duct and battery cover.

Operating Inspection
1. Disconnect the transaxle connector (secondary).

Caution:
^ Do not apply battery position voltage to terminals A and B 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 and B 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.

Resistance Inspection (Off-Vehicle Inspection)
1. Remove the battery duct and battery cover.
2. Disconnect the negative battery cable.
3. Remove the battery, battery box and battery tray.
4. Remove the solenoid valve(s).
5. Measure the resistance of each solenoid valve individually.
^ If not as specified, replace the solenoid valve.
6. Install the solenoid valve(s).
7. Install the battery, battery box and battery tray.
8. Connect the negative battery cable.
9. Install the battery duct and battery cover.
