Solenoid Valve Inspection - FS5A-EL

SOLENOID VALVE INSPECTION [FS5A-EL]

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.

Primary Control Valve Body

On-vehicle inspection

1. Disconnect the coupler component connector.
a. Disconnect the negative battery cable.

b. Remove the air cleaner component. Service and Repair

c. Disconnect the coupler component connector.






2. Measure the resistance between the coupler component terminals.






- If there is any malfunction, inspect the coupler component for continuity.
If coupler component has no malfunction, perform the "Off-vehicle inspection".
Solenoid valve specification





Operating inspection

CAUTION:
- Do not apply battery position voltage to terminals for more than 3 s.

NOTE:
- Because the operation sound of the solenoid valve is small, perform inspection in a quiet place.

1. Disconnect the coupler component connector.
a. Disconnect the negative battery cable.

b. Remove the air cleaner component. Service and Repair

c. Disconnect the coupler component connector.






2. Apply battery positive voltage to the coupler component terminals A, B, C, F or G and battery negative voltage to GND, and verify that operating sound is heard from solenoid valve.






- If the operation sound is not heard, inspect the coupler component for continuity.
If coupler component has no malfunction, perform the "Off-vehicle inspection".

3. Apply battery positive voltage to the coupler component terminal D and battery negative voltage to terminal I, and verify that operating sound is heard from solenoid valve.






- If the operation sound is not heard, inspect the coupler component for continuity.
If coupler component has no malfunction, perform the "Off-vehicle inspection".

Off-Vehicle inspection

1. Measure the resistance between the coupler component terminals.

- If there is any malfunction, replace the solenoid valve. Service and Repair
