DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1. Select INTELLIGENT KEY of BCM using CONSULT.

2. Select INSIDE ANT DIAGNOSIS in WORK SUPPORT mode.

3. Perform inside key antenna (INSIDE ANT DIAGNOSIS) on WORK SUPPORT of INTELLIGENT KEY.

4. Check BCM for DTC.
Is inside key antenna DTC detected?

YES

>> Refer to 

DLK-70, "Diagnosis Procedure"

.

NO

>> Inside key antenna (trunk room) is OK.

Diagnosis Procedure

INFOID:0000000009268746

Regarding Wiring Diagram information, refer to 

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

.

1.

CHECK INSIDE 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
