Diagnosis Procedure

INFOID:0000000009175706

Regarding Wiring Diagram information, refer to 

DLK-74, "Wiring Diagram"

.

1.

CHECK OUTSIDE KEY ANTENNA INPUT SIGNAL 1

1. Turn ignition switch OFF.

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

Is the inspection result normal?

YES

>> Replace BCM. Refer to 

BCS-80, "Removal and Installation"

.

NO

>> GO TO 2.

2.

CHECK OUTSIDE KEY ANTENNA CIRCUIT

1. Disconnect BCM connector and outside key antenna (driver side) connector.

2. Check continuity between BCM harness connector and outside key antenna (driver side) harness connec-

tor.

3. Check continuity between BCM harness connector and ground.
