B2623 INSIDE ANTENNA
2.
CHECK INSIDE KEY ANTENNA CIRCUIT
1. Disconnect BCM connector and inside key antenna (luggage room) connector.
2. Check continuity between BCM harness connector and inside key antenna (luggage room) harness con-
nector.
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 INSIDE KEY ANTENNA INPUT SIGNAL 2
1. Replace inside key antenna (luggage room). (New antenna or other antenna)
2. Connect BCM connector and inside key antenna (luggage room) connector.
3. Check signal between BCM harness connector and ground using oscilloscope.
Is the inspection result normal?
YES
>> Replace inside key antenna (luggage room). Refer to
DLK-315, "LUGGAGE ROOM : Removal
.
NO
>> Replace BCM. Refer to
