Diagnosis Procedure

INFOID:0000000010309234

1.

CHECK FUSE

Check that the fuse is not fusing.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace the fuse after repairing the applicable circuit.

2.

CHECK ECM POWER SUPPLY

1.

Reinsert the fuse pulled out.

2.

Turn ignition switch ON.

3.

Check the voltage between ECM harness connector and ground.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> GO TO 3.

DTC No.
