CHECK COMMUNICATION CIRCUIT HARNESS.

Measure the voltage between ECM harness connector terminal and engine ground.

Connector & terminal

2.5 L model

(B136) No. 26 (+) — Engine ground (−):

(B136) No. 34 (+) — Engine ground (−):

2.0 L model

(B135) No. 11 (+) — Engine ground (−):

(B135) No. 12 (+) — Engine ground (−):

Diesel engine model

(B135) No. 5 (+) — Engine ground (−):

QUESTION
Is the voltage 0 V?
Yes	No
	Because the battery voltage or ignition switch “ON” circuit is shorted, repair the harness between the body integrated unit and ECM.
