2.

Check continuity between NATS antenna amp. harness connector and fuse block (J/B) harness connec-
tor.

3.

Check continuity between NATS antenna amp. harness connector and ground.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-44, "Intermittent Incident"

.

NO

>> Repair or replace harness.

4.

CHECK NATS ANTENNA AMP. GROUND CIRCUIT 

1.

Check continuity between NATS antenna amp. harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace harness.

5.

CHECK NATS ANTENNA AMP. COMMUNICATION SIGNAL 

Check voltage signal between NATS antenna amp. harness connector and ground using an oscilloscope.

Is the inspection result normal?

YES

>> Replace NATS antenna amp. Refer to 

SEC-187, "Removal and Installation"

.

NO

>> GO TO 6.

6.

CHECK NATS ANTENNA AMP. COMMUNICATION SIGNAL CIRCUIT

1.

Disconnect BCM connector.

2.

Check continuity between NATS antenna amp. harness connector and BCM harness connector.

3.

Check continuity between BCM harness connector and ground.
