2. Check continuity between BCM harness connector and outside key antenna (RH) harness connector.

3. Check continuity between BCM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness.

3.

CHECK OUTSIDE KEY ANTENNA INPUT SIGNAL 2

1. Replace outside key antenna (RH). (New antenna or other antenna)

2. Connect BCM connector and outside key antenna (RH) connector.

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

Is the inspection result normal?

YES

>> Replace front outside handle RH (outside key antenna). Refer to 

DLK-207, "PASSENGER SIDE :

Removal and Installation"

.
