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 (primary).

(1)  Disconnect the negative battery cable.
(2)  Remove the air cleaner component. (SeeINTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L5].)
(3)  Disconnect the coupler component connector (primary).

2.  Measure the resistance between the following terminals.

•  If there is any malfunction, inspect the coupler component (primary). (SeeTRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [FS5A-EL].)

Off‐Vehicle Inspection

1.  Disconnect the negative battery cable

2.  Remove the solenoid valve. (See SOLENOID VALVE REMOVAL/INSTALLATION (PRIMARY CONTROL VALVE BODY) [FS5A-EL].)

3.  Measure the resistance of each solenoid valve individually.

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

Operating Inspection

1.  Disconnect the coupler component connector (primary).

(1)  Disconnect the negative battery cable.
(2)  Remove the air cleaner component. (SeeINTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L5].)
(3)  Disconnect the coupler component connector (primary).

Caution
•  Do not apply battery position voltage to terminals 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, B, C, F or G 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 (primary). (SeeTRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION [FS5A-EL].)

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

•  If the click is not heard, inspect the coupler component (primary). (SeeTRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION [FS5A-EL].)
