YES

>> GO TO 5.

NO

>> GO TO 4.

4.

DETECT MALFUNCTIONING PART

Check the following.
• Harness for short to ground between ECM and IPDM E/R
• ECM relay

>> Repair or replace error-detected parts.

5.

CHECK 15A FUSE

1.

Disconnect 15A fuse (No. 52) from IPDM E/R.

2.

Disconnect 15A fuse (No. 55) from IPDM E/R.

3.

Check the fuse.

Is the inspection result normal?

YES

>> Perform intermittent incident. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> Replace malfunctioning fuse.
