id1502b6026500

Description

U0001:88

•  Unit communication error (HS-CAN)

U0100:00

•  Communication error with PCM

U0131:00

•  Communication error with electric power steering (EPS) control module

U0140:00

•  Communication error with BCM

U0155:00

•  Communication error with instrument cluster

Detection condition

•  U0001:88

―  The adaptive front lighting system (AFS) control module detected CAN bus communication line (HS-CAN) malfunction ten times continuously.

•  U0100:00

―  The adaptive front lighting system (AFS) control module could not receive CAN signal from the PCM for 5 s or more.

•  U0131:00

―  The adaptive front lighting system (AFS) control module could not receive CAN signal from the electric power steering (EPS) control module for 5 s or more.

•  U0140:00

―  The adaptive front lighting system (AFS) control module could not receive CAN signal from the BCM for 5 s or more.

•  U0155:00

―  The adaptive front lighting system (AFS) control module could not receive CAN signal from the instrument cluster for 5 s or more.

Fail-safe

•  U0001:88

―  The swivel actuator is moved to the center.

―  The headlight leveling actuator is stopped at the position when the malfunction is determined.

•  U0100:00

―  The swivel actuator is moved to the center.

―  The headlight leveling actuator is stopped at the position when the malfunction is determined.

•  U0131:00

―  The swivel actuator is moved to the center.

―  Control of the headlight auto leveling system is continued.

•  U0140:00

―  The swivel actuator is moved to the center.

―  The headlight leveling actuator is stopped at the position when the malfunction is determined.

•  U0155:00

―  The swivel actuator is moved to the center.

―  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 adaptive front lighting system (AFS) control module

•  Malfunction in CAN communication line between electric power steering (EPS) control module and adaptive front lighting system (AFS) control module

•  Malfunction in CAN communication line between BCM and adaptive front lighting system (AFS) control module

•  Malfunction in CAN communication line between instrument cluster and adaptive front lighting system (AFS) control module
