id1503b6090400


Description

•  Traffic sign is not displayed in the active driving display while the vehicle is being driven.
•  Traffic sign turns off in the active driving display while the vehicle is being driven.

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.
•  Traffic sign recognition system (TSR) function is off using personalization feature
•  Connectivity master unit (CMU) malfunction
•  Forward sensing camera (FSC) malfunction
•  Vehicle is driven for a certain period of time while traffic sign cannot be found
•  Making left/right turns
•  Vehicle speed exceeds vehicle speed of displayed traffic sign by 30 km/h or more
•  NAVI SD card is not inserted
•  Active driving display malfunction

Diagnostic Procedure

Step

Inspection

Action

1
VERIFY PERSONALIZATION FEATURE SETTING
•  Verify that the traffic sign recognition system (TSR) function is off using the personalization feature.
•  Is the traffic sign recognition system (TSR) function off?
Yes
Perform the personalization features setting in consultation with the customer.
No
Go to the next step.
2
VERIFY DTCs
•  Display the connectivity master unit (CMU) and forward sensing camera (FSC) DTCs using the M-MDS.
•  Is a DTC displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
Go to the next step.
3
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.
4
VERIFY DRIVING CONDITION
•  Ask the customer if the condition was any of the following conditions when the malfunction occurred.
?  Vehicle is driven for a certain period of time while traffic sign cannot be found
?  Making left/right turns
?  Vehicle speed exceeds vehicle speed of displayed traffic sign by 30 km/h or more
?  NAVI SD card is not inserted
•  Is any of the above driving conditions met?
Yes
The vehicle is normal. (Explain to the customer that a traffic sign is not displayed because the operation of the traffic sign recognition system (TSR) is canceled or depending on the driving conditions.)
Complete the symptom troubleshooting.
No
Go to the next step.
5
INSPECT ACTIVE DRIVING DISPLAY
•  Inspect the active driving display.
•  Is the active driving display normal?
Yes
Go to the next step.
No
Replace the active driving display, then go to the next step.
6
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).
