Diagnostic Procedure

Step

Inspection

Results

Action

1

INSPECT DRIVER MONITORING CAMERA UNIT FOR MALFUNCTION

•  Perform the DTC inspection for the driver monitoring camera unit.
(See DTC INSPECTION.)

―  U3000:04

―  U3000:42

―  U3000:49

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [DRIVER MONITORING CAMERA UNIT (E)].)

No

Go to the next step.

2

INSPECT DRIVER MONITORING CAMERA UNIT CONNECTOR FOR MALFUNCTION

•  Inspect the applicable connector and terminal.
(See CONNECTOR INSPECTION.)

•  Are the connector and terminal normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification procedure.

3

INSPECT CENTER DISPLAY CONNECTOR FOR MALFUNCTION

•  Inspect the applicable connector and terminal.
(See CONNECTOR INSPECTION.)

•  Are the connector and terminal normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification procedure.

4

INSPECT DRIVER MONITORING CAMERA LED POWER SUPPLY CIRCUIT, VOLTAGE DETECT CIRCUIT, CONTROL CIRCUIT, AND GROUND CIRCUIT FOR SHORT TO GROUND

•  Inspect the applicable circuit for a short to ground.
(See CIRCUIT INSPECTION.)

•  Is the circuit normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification procedure.

5

INSPECT DRIVER MONITORING CAMERA LED POWER SUPPLY CIRCUIT, VOLTAGE DETECT CIRCUIT, CONTROL CIRCUIT, AND GROUND CIRCUIT FOR SHORT TO POWER SUPPLY

•  Inspect the applicable circuit for a short to power supply.
(See CIRCUIT INSPECTION.)

•  Is the circuit normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification procedure.

6

INSPECT DRIVER MONITORING CAMERA LED POWER SUPPLY CIRCUIT, VOLTAGE DETECT CIRCUIT, CONTROL CIRCUIT, AND GROUND CIRCUIT FOR OPEN CIRCUIT

•  Inspect the applicable circuit for open circuit.
(See CIRCUIT INSPECTION.)

•  Is the circuit normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification procedure.

7

INSPECT DRIVER MONITORING CAMERA LED FOR MALFUNCTION DEPENDING ON REPEATABILITY

•  Install/connect the part removed/disconnected during the troubleshooting procedure.

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Perform the DTC inspection for the driver monitoring camera unit.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

If the CAN communication is normal, replace the center display and perform the repair completion verification.

(See CENTER DISPLAY REMOVAL/INSTALLATION.)

No

Go to repair completion verification 2.

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

•  Install/connect the part removed/disconnected during the troubleshooting procedure.

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Perform the DTC inspection for the driver monitoring camera unit.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction recurs, replace the driver monitoring camera unit, then go to the next step.
(See DRIVER MONITORING CAMERA UNIT REMOVAL/INSTALLATION [(E)].)
