Component Tests and General Diagnostics

SOLENOID VALVE INSPECTION [FN4A-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.

On-Vehicle Inspection

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

b. 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".

Operating Inspection

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

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

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

b. 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 "click" is not heard, inspect the coupler component.
- 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 "click" is not heard, inspect the coupler component.
- If coupler component has no malfunction, perform the "Off-Vehicle Inspection".

Off-Vehicle Inspection

1. Measure the resistance of each solenoid valve individually.

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