DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC C0428 is displayed with DTC U1232, first perform the confirmation procedure (trouble diagnosis) for
DTC U1232. 

Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

AV-205, "DTC Description"

.

NO

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

WITH CONSULT

1.

Turn the ignition switch ON.

2.

Turn ignition switch OFF and wait at least 30 seconds.

3.

Turn ignition switch ON and wait at least 30 seconds or more.

4.

Select “Self Diagnostic Result” mode of “AVM” using CONSULT.

5.

Check DTC.

Is DTC U0428 detected?

YES

>> Refer to 

AV-176, "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:0000000010714840

1.

ADJUST THE NEUTRAL POSITION OF THE STEERING ANGLE SENSOR

When U0428 is detected, adjust the neutral position of the steering angle sensor.

>> Perform adjustment of the neutral position of the steering angle sensor. Refer to 

BRC-99, "Work

Procedure"

.

CAUTION:

For vehicles with VDC, adjust the steering angle sensor neutral position on the ABS actuator control
unit side.

NAVI CONTROL UNIT

NAVI CONTROL UNIT : DTC Description

INFOID:0000000010714841

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on board multi-
plex communication line with high data communication speed and excellent error detection ability. A modern
vehicle is equipped with many ECMs, and each control unit shares information and links with other control
units during operation (not independent). In CAN communication, 2 control units are connected with 2 commu-
nication lines (CAN H-line and CAN L-line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to 

LAN-41, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"

 for details of the

communication signal.

DTC DETECTION LOGIC

POSSIBLE CAUSE

CAN communication system

FAIL-SAFE

The system using the CAN communication signal from control unit which cannot communicate does not func-
tion

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 the ignition switch ON.

2.

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

3.

Turn ignition switch ON and wait at least 30 seconds or more.

4.

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

5.

Check DTC.

Is DTC U1000 detected?

YES

>> Refer to 

AV-177, "NAVI CONTROL UNIT : Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

>> Confirmation after repair: INSPECTION END

NAVI CONTROL UNIT : Diagnosis Procedure

INFOID:0000000010714842

1.

PERFORM DTC CONFIRMATION PROCEDURE AGAIN

With CONSULT

1.

Turn ignition switch ON.

2.

Erase DTC.

3.

Perform DTC confirmation procedure again. Refer to 

AV-177, "NAVI CONTROL UNIT : DTC Description"

.

Is DTC U1000 detected again?

YES

>> Perform the trouble diagnosis for CAN communication system. Refer to
