YES

>> Refer to 

DLK-74, "Diagnosis Procedure"

.

NO

>> Outside key antenna (RH) is OK.

Diagnosis Procedure

INFOID:0000000009268750

Regarding Wiring Diagram information, refer to 

DLK-37, "INTELLIGENT KEY SYSTEM : Wiring Diagram"

.

1.

CHECK OUTSIDE KEY ANTENNA INPUT SIGNAL 1

1. Turn ignition switch ON.

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

Is the inspection result normal?

YES
