side.

œ

Resistance between terminal No. 2 and earth.

OK: 2

W

or less

Q: Is the check result normal?

YES :

Go to Step 14 .

NO :

Check and repair harness between B-111

(terminal No. 2) ignition coil connector and
body earth, also between B-110 (terminal
No. 2) ignition coil connector and body
earth.

œ
