CHECK HARNESS BETWEEN ECM AND SUCTION CONTROL VALVE CONNECTOR.

1) Turn the ignition switch to OFF.

2) Measure the resistance of harness between ECM connector and suction control valve connector.

Connector & terminal

(B134) No. 20 — (E123) No. 1:

(B134) No. 7 — (E123) No. 2:

QUESTION

Is the resistance less than 1 Ω?

Yes No

Repair the harness and connector.

NOTE:

In this case, repair the following item:

• Open circuit of harness between ECM connector and suction control valve connector

• Poor contact of coupling connector
