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

id051721807900


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 coupler component connector (secondary).

(1)  Disconnect the negative battery cable.
(2)  Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [L8, LF, L5].)
(3)  Disconnect the coupler component connector (secondary).

2.  Measure the resistance between the following terminals.

•  If there is any malfunction, inspect the coupler component (secondary). (SeeSOLENOID VALVE REMOVAL/INSTALLATION (SECONDARY CONTROL VALVE BODY) [FS5A-EL].)

Off‐Vehicle Inspection

1.  Disconnect the negative battery cable.

2.  Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [L8, LF, L5].)

3.  Remove the solenoid valve. (SeeSOLENOID VALVE REMOVAL/INSTALLATION (SECONDARY CONTROL VALVE BODY) [FS5A-EL].)

4.  Measure the resistance of each solenoid valve individually.

•  If there is any malfunction, replace the solenoid valve (secondary). (SeeSOLENOID VALVE REMOVAL/INSTALLATION (SECONDARY CONTROL VALVE BODY) [FS5A-EL].)

Operating Inspection

1.  Disconnect the coupler component connector (secondary).

(1)  Disconnect the negative battery cable.
(2)  Remove the battery and battery tray. (SeeBATTERY REMOVAL/INSTALLATION [L8, LF, L5].)
(3)  Disconnect the coupler component 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 coupler component connector (secondary). (SeeSOLENOID VALVE INSPECTION (SECONDARY CONTROL VALVE BODY) [FS5A-EL].)
