Disconnect 15 A fuse (No. 64) from IPDM E/R.

2.

Check 15 A fuse for blown.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> Replace 15 A fuse.

5.

CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT-I

1.

Check voltage between ECM harness connector and ground under the following conditions.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> GO TO 6.

6.

CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT-II

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Disconnect IPDM E/R harness connector E15.

4.

Check the continuity between ECM harness connector and IPDM E/R harness connector.

5.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 8.
