CHECK INSIDE KEY ANTENNA CIRCUIT

1. Turn power switch OFF.

2. Disconnect BCM connector and inside key antenna (rear seat) connector.

3. Check continuity between BCM harness connector and inside key antenna (rear seat) harness connector.

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 (rear seat). (New antenna or other antenna)

2. Connect BCM connector and inside key antenna (rear seat) connector.

3. Turn power switch ON.

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

Is the inspection result normal?
