1. Turn ignition switch OFF.

2. Disconnect BCM connector and inside key antenna (trunk room) connector.

3. Check continuity between BCM harness connector and inside key antenna (trunk room) harness connec-

tor.

4. Check continuity between BCM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness.

3.

CHECK INSIDE KEY ANTENNA INPUT SIGNAL 2

1. Replace inside key antenna (trunk room). (New antenna or other antenna)

2. Connect BCM connector and inside key antenna (trunk room) connector.

3. Turn ignition switch ON.

4. Check signal between BCM harness connector and ground using oscilloscope.

Is the inspection result normal?

YES

>> Replace inside key antenna (trunk room). Refer to 

DLK-176, "LUGGAGE ROOM : Removal and

Installation"
