id090277073100

Description

U0001:88

•  Unit communication error (HS-CAN)

U0100:00

•  Communication error with PCM

U0140:00

•  Communication error with front body control module (FBCM)

U0155:00

Detection condition
•  U0001:88
?  The auto leveling control module detected CAN bus communication line (HS-CAN) malfunction ten times continuously.
•  U0100:00
?  The auto leveling control module could not receive CAN signal from the PCM for 5 s or more.
•  U0140:00
?  The auto leveling control module could not receive CAN signal from the front body control module (FBCM) for 5 s or more.
•  U0155:00
?  The auto leveling control module could not receive CAN signal from the instrument cluster for 5 s or more.
Fail-safe
•  U0001:88
?  The headlight leveling actuator is stopped at the position when the malfunction is determined.
•  U0100:00
?  The headlight leveling actuator is stopped at the position when the malfunction is determined.
•  U0140:00
?  The headlight leveling actuator is stopped at the position when the malfunction is determined.
•  U0155:00
?  Control of the headlight auto leveling system is continued.
Possible cause
•  Malfunction in CAN bus communication line
•  Malfunction in CAN communication line between PCM and auto leveling control module
•  Malfunction in CAN communication line between front body control module (FBCM) and auto leveling control module
•  Malfunction in CAN communication line between instrument cluster and auto leveling control module
