CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR CONNECTOR.

1) Turn the ignition switch to OFF.

2) Disconnect the connectors from tumble generator valve and ECM connector.

3) Measure the resistance between tumble generator valve actuator and ECM connector.

Connector & terminal

(E51) No. 1 — (B137) No. 12:

(E51) No. 2 — (B137) No. 13:

QUESTION

Is the resistance less than 1 Ω?

Yes No

Repair the open circuit between ECM and tumble generator valve connector.

NOTE:

In this case, repair the following item:

Open circuit of harness between ECM and tumble generator valve actuator connector

Poor contact of coupling connector
