Inspection by fault code

WARNING: This page is about a different car, the 2024 Genesis G80. However, it is still accessible from the selected car via links, so may be relevant.

Check the DTC of IFS using a diagnostic device.

Inspect the relevant parts with reference to the table below.

No.	Inspection	countermeasure for occurring situation
1	DTC CODE: When B16F*87 (2 digits from rear: 87) occurs	- DTC that occurs when the lamp outside (vehicle side) is out of order
		→ Controller inspection is required except lamp
		1) B16F087: Lamp Control Signal Fault
		→ IBU/ICU/MFSW/WHL controllers is required
		2) B16F187: IFS Control Signal Fault
		→ IBU/FR_CMR controllers is required
2	When driving at high speed (over 100 km/h) during IFS operation, the IFS at the driver's side turns off entirely.	When detecting a vehicle in IFS high-speed mode, the entire light-off logic is being applied to the high beam at the driver's side. (The LED part without vehicle also turns off)
2		→ This function is for anti-glare of opposing vehicles by the high beam off responsiveness while driving at high speed and does not mean the headlamp problem.
3	Problems of parts such as lamp modification/overseas purchase, etc.	1) Left/right lighting patterns can be different.
		2) Possibility of warning light to turn ON due to the parameter input error.
		3) Some IFS functions may not work due to the parameter input error.
4	When pop-up message 'IFS is canceled as the visibility of the camera is limited due to the external environment' is displayed on the instrument cluster.	Securing front visibility of the camera is required: Remove foreign materials on the camera lens or windshield glass
