U1300 AV COMM CIRCUIT

U1300 AV COMM CIRCUIT

DTC Description

INFOID:0000000010714887

U1300 is displayed when the AV signal error is detected for the multi AV system. It is always displayed
together with the error of the control unit connected to the NAVI control unit via AV communication.

DTC DETECTION LOGIC

POSSIBLE CAUSE

• AV communication circuit
• NAVI control unit
• Combination meter

FAIL-SAFE

The system of ECU which detected abnormalities does not operate.

DTC CONFIRMATION PROCEDURE

NOTE:
• The auto ACC function allows the accessory power supply for a certain period of time even after ignition

switch OFF. For this reason, when performing diagnosis, turn the ignition switch OFF and wait for 3 minutes
with the driver's door opened.

• The operation of the vehicle during standby may cause an accessory power supply.

1.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1.

Turn ignition switch ON.

2.

Turn ignition switch OFF and wait for 3 minutes with the driver's door opened.

3.

Turn ignition switch ON.

4.

Select “Self Diagnostic Result” mode of “MULTI AV” using CONSULT.

5.

Check DTC.

Is DTC U1300 detected?

YES

>> Refer to 

AV-220, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010714888

NOTE:
• The auto ACC function allows the accessory power supply for a certain period of time even after ignition

switch OFF. For this reason, when performing diagnosis, turn the ignition switch OFF and wait for 3 minutes
with the driver's door opened.

• The operation of the vehicle during standby may cause an accessory power supply.

1.

CHECK CONTINUITY OF AV COMMUNICATION CIRCUIT (NAVI CONTROL UNIT 

⇔

 COMBINATION

METER)

1.

Turn the ignition switch OFF. 

2.

Disconnect the connectors of NAVI control unit and combination meter.

3.

Check continuity between NAVI control unit harness connector and combination meter harness connector.
