DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch ON.

2. Check Self Diagnostic Result mode of BCM using CONSULT.
Is outside key antenna DTC detected?

YES

>> Refer to

DLK-74, "Diagnosis Procedure"

.

NO

>> Outside key antenna (RH) is OK.

Diagnosis Procedure

INFOID:0000000009268750

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-69, "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 (RH) connector.

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