Diagnostic Procedure

Step

Inspection

Results

Action

1

INSPECT REAR SIDE RADAR SENSOR FOR MALFUNCTION

•  Perform the DTC inspection for the rear side radar sensor.
(See DTC INSPECTION.)

•  Is a DTC related to an internal malfunction displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [REAR SIDE RADAR SENSOR (E)].)

No

Go to the next step.

2

VERIFY REAR BUMPER INSTALLATION CONDITION

•  Verify the rear bumper installation condition.
(See REAR BUMPER REMOVAL/INSTALLATION.)

•  Is the installation condition normal?

Yes

Go to the next step.

No

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

(See REAR BUMPER REMOVAL/INSTALLATION.)

3

VERIFY REAR SIDE RADAR SENSOR INSTALLATION CONDITION

•  Verify the rear side radar sensor installation condition.
(See REAR SIDE RADAR SENSOR REMOVAL/INSTALLATION.)

•  Is the installation condition normal?

Yes

Perform the rear side radar sensor radar aiming.

(See REAR SIDE RADAR SENSOR AIMING.)

Go to repair completion verification.

No

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

(See REAR SIDE RADAR SENSOR REMOVAL/INSTALLATION.)

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 rear side radar sensor.
(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 [L.H.D. (E)].)

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].)

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

•  If the malfunction recurs, replace the rear side radar sensor (LH)/(RH), then go to the next step.
(See REAR SIDE RADAR SENSOR REMOVAL/INSTALLATION.)

No

Go to the next step.

VERIFY IF OTHER DTC IS DISPLAYED

•  Perform the DTC inspection.
(See DTC INSPECTION.)

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
