Detection condition
•  U0001:88
?  The adaptive LED headlights control module detected CAN bus communication line (HS-CAN) malfunction ten times continuously.
•  U0100:00
?  The adaptive LED headlights control module could not receive CAN signal from the PCM for 5 s or more.
•  U0121:00
?  The adaptive LED headlights control module could not receive CAN signal from the DSC HU/CM for 5 s or more.
•  U0131:00
?  The adaptive LED headlights control module could not receive CAN signal from the electric power steering (EPS) control module for 5 s or more.
•  U0140:00
?  The adaptive LED headlights control module could not receive CAN signal from the front body control module (FBCM) for 5 s or more.
•  U0155:00
?  The adaptive LED headlights control module could not receive CAN signal from the instrument cluster for 5 s or more.
•  U0214:00
?  The adaptive LED headlights control module could not receive CAN signal from the start stop unit for 5 s or more.
•  U023A:00
?  The adaptive LED headlights control module could not receive CAN signal from the forward sensing camera (FSC) for 5 s or more.
Fail-safe
•  U0001:88
?  When the setting is on using the personalization feature, the headlights HI turn on. (When setting is off using personalization feature, headlight HI illumination on/off depends on control by front body control module (FBCM))
?  The headlight leveling actuator is stopped at the position when the malfunction is determined.
•  U0100:00
?  When the setting is on using the personalization feature, the headlights HI turn on. (When setting is off using personalization feature, headlight HI illumination on/off depends on control by front body control module (FBCM))
?  The headlight leveling actuator is stopped at the position when the malfunction is determined.
•  U0121:00
?  When the setting is on using the personalization feature, the headlights HI turn on. (When setting is off using personalization feature, headlight HI illumination on/off depends on control by front body control module (FBCM))
?  Control of the headlight auto leveling system is continued.
•  U0131:00
?  When the setting is on using the personalization feature, the headlights HI turn on. (When setting is off using personalization feature, headlight HI illumination on/off depends on control by front body control module (FBCM))
?  Control of the headlight auto leveling system is continued.
•  U0140:00
?  When the setting is on using the personalization feature, the headlights HI turn on. (When setting is off using personalization feature, headlight HI illumination on/off depends on control by front body control module (FBCM))
?  The headlight leveling actuator is stopped at the position when the malfunction is determined.
•  U0155:00
?  When the setting is on using the personalization feature, the headlights HI turn on. (When setting is off using personalization feature, headlight HI illumination on/off depends on control by front body control module (FBCM))
?  Control of the headlight auto leveling system is continued.
•  U0214:00
?  When the setting is on using the personalization feature, the headlights HI turn on. (When setting is off using personalization feature, headlight HI illumination on/off depends on control by front body control module (FBCM))
?  The headlight leveling actuator is stopped at the position when the malfunction is determined.
•  U023A:00
?  When the setting is on using the personalization feature, the headlights HI turn on. (When setting is off using personalization feature, headlight HI illumination on/off depends on control by front body control module (FBCM))
?  Control of the headlight auto leveling system is continued.
