2) Measure the resistance between ignition coil connector and engine ground.

Connector & terminal

(E31) No. 2 — Engine ground:

(E32) No. 2 — Engine ground:

(E33) No. 2 — Engine ground:

(E34) No. 2 — Engine ground:

QUESTION

Is the resistance less than 5 Ω?

Yes No

Repair the harness and connector.

NOTE:

In this case, repair the following item:

• Open circuit of harness between ECM and ignition coil connector

• Open circuit in harness between ECM and engine ground terminal

• Poor contact of coupling connector
