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.  Perform the following procedures.

(1)  Disconnect the negative battery cable.

(2)  Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 1.8, MZR 2.0, MZR 2.5].) (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.0 DISI].)

(3)  Disconnect the coupler component connector (primary).

2.  Measure the resistance between the coupler component (primary) 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 valves is small, perform inspection in a quiet place.

1.  Perform the following procedures.

(1)  Disconnect the negative battery cable.

(2)  Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 1.8, MZR 2.0, MZR 2.5].) (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.0 DISI].)

(3)  Disconnect the coupler component connector (primary).

2.  Apply battery positive voltage to the coupler component (primary) 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 (primary) 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 (primary). (See SOLENOID VALVE REMOVAL/INSTALLATION (PRIMARY CONTROL VALVE BODY) [FS5A-EL].)
