CHECK HARNESS BETWEEN IMM ECM AND ECM.

1) Disconnect the harness connector from the ECM and IMM ECM.

2) Measure the resistance between IMM ECM harness connector terminal and ECM harness connector terminal.

Connector & terminal

2.0 L model

(B141) No. 10 — (B135) No. 23

2.5 L model

(B141) No. 10 — (B136) No. 26

QUESTION

Is the resistance less than 10 Ω?

Yes No
