FALSE DETECTION/INCORRECT DISPLAY OF TRAFFIC SIGN [TRAFFIC SIGN RECOGNITION SYSTEM (TSR)]

• The detection performance of the forward sensing camera (FSC) has limitations and the traffic sign recognition system (TSR) may not operate normally. For the detection performance limitations, refer to the [FORWARD SENSING CAMERA (FSC)] in the technical guide.

• The forward sensing camera (FSC) operation record can be verified using the M-MDS.

Step	Inspection	Action
1	VERIFY DTCs • Display the connectivity master unit (CMU) and the forward sensing camera (FSC) DTCs using the M-MDS. (See DTC INSPECTION [CONNECTIVITY MASTER UNIT].) (See DTC INSPECTION [FORWARD SENSING CAMERA (FSC)].) • Is a DTC displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [CONNECTIVITY MASTER UNIT].) (See DTC TABLE [FORWARD SENSING CAMERA (FSC)].)
No	Go to the next step.
2	INSPECT PHENOMENON DUE TO DETECTION PERFORMANCE LIMITATIONS • Refer to the new vehicle instruction and inspect the detection performance of the forward sensing camera (FSC). • Inspect the forward sensing camera (FSC) operation record using the M-MDS. • Are the applicable items for the detection performance displayed?	Yes	The vehicle is normal. (Explain to the customer that the lane-keep assist system may not operate due to the detection performance limitations of the forward sensing camera (FSC).) Complete the symptom troubleshooting.
No	Go to the next step.
3	INSPECT ACTIVE DRIVING DISPLAY • Inspect the active driving display. (See ACTIVE DRIVING DISPLAY INSPECTION.) • Is the active driving display normal?	Yes	Go to the next step.
No	Replace the active driving display, then go to the next step. (See ACTIVE DRIVING DISPLAY REMOVAL/INSTALLATION.)
4	VERIFY MALFUNCTION SYMPTOM • Has the malfunction symptom been eliminated?	Yes	Complete the symptom troubleshooting. (Explain repair contents to customer).
No	Repeat the diagnosis from Step 1. If the malfunction is not resolved, replace the forward sensing camera (FSC). (See FORWARD SENSING CAMERA (FSC) REMOVAL/INSTALLATION.)

Step

Inspection

Action

VERIFY DTCs

• Display the connectivity master unit (CMU) and the forward sensing camera (FSC) DTCs using the M-MDS.

(See DTC INSPECTION [CONNECTIVITY MASTER UNIT].)

(See DTC INSPECTION [FORWARD SENSING CAMERA (FSC)].)

• Is a DTC displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [CONNECTIVITY MASTER UNIT].)

(See DTC TABLE [FORWARD SENSING CAMERA (FSC)].)

Go to the next step.

INSPECT PHENOMENON DUE TO DETECTION PERFORMANCE LIMITATIONS

• Refer to the new vehicle instruction and inspect the detection performance of the forward sensing camera (FSC).

• Inspect the forward sensing camera (FSC) operation record using the M-MDS.

• Are the applicable items for the detection performance displayed?

Yes

The vehicle is normal. (Explain to the customer that the lane-keep assist system may not operate due to the detection performance limitations of the forward sensing camera (FSC).)

Complete the symptom troubleshooting.

Go to the next step.

INSPECT ACTIVE DRIVING DISPLAY

• Inspect the active driving display.

(See ACTIVE DRIVING DISPLAY INSPECTION.)

• Is the active driving display normal?

Yes

Go to the next step.

Replace the active driving display, then go to the next step.

(See ACTIVE DRIVING DISPLAY REMOVAL/INSTALLATION.)

VERIFY MALFUNCTION SYMPTOM

• Has the malfunction symptom been eliminated?

Yes

Complete the symptom troubleshooting. (Explain repair contents to customer).

Repeat the diagnosis from Step 1.

If the malfunction is not resolved, replace the forward sensing camera (FSC).
