SOLENOID VALVE INSPECTION [FS5A-EL]

id051721293100

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.  Perform the following procedures.

(1)  Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [LF, L5].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)
(2)  Disconnect the negative battery cable.
(3)  Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [LF, L5].) (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)
(4)  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“. (See Off-Vehicle inspection.)

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.  Perform the following procedures.

(1)  Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [LF, L5].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)
(2)  Disconnect the negative battery cable.
(3)  Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [LF, L5].) (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)
(4)  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“. (See 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“. (See Off-Vehicle inspection.)


Off-Vehicle inspection

1.  Measure the resistance between the solenoid valve terminals.

•  If there is any malfunction, replace the solenoid valve. (See SOLENOID VALVE REMOVAL/INSTALLATION [FS5A-EL].)
