DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch ON.

2. Check “Self Diagnostic Result” mode of “BCM” using CONSULT.
Is DTC detected?

YES

>> Refer to 

DLK-60, "Diagnosis Procedure"

.

NO

>> Outside key antenna (LH) is OK.

Diagnosis Procedure

INFOID:0000000009515841

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

>> Replace BCM. Refer to 

BCS-67, "Removal and Installation"

.

NO

>> GO TO 2.

2.

CHECK OUTSIDE KEY ANTENNA CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect BCM connector and outside key antenna (LH) connector.

3. Check continuity between BCM harness connector and outside key antenna (LH) harness connector.
