id1503b6091000

Description

• Traffic sign is displayed in the active driving display even if the traffic sign recognition system (TSR) is turned off.

Possible Cause

Note

• 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.

• Connectivity master unit (CMU) malfunction

• Active driving display malfunction

Diagnostic Procedure

Step	Inspection		Action
1	VERIFY DTCs • Display the DTC for the connectivity master unit (CMU) using the M-MDS. (See DTC INSPECTION [CONNECTIVITY MASTER UNIT].) • Is a DTC displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [CONNECTIVITY MASTER UNIT].)
1		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.
2		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.
3		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).
4		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.)
