id1502b6026500

Description

U0001:88

•  Unit communication error (HS-CAN)

U0100:00

•  Communication error with PCM

U0131:00

•  Communication error with EPS control module

U0140:00

•  Communication error with front body control module (FBCM)

U0155:00

•  Communication error with instrument cluster

Detection condition

•  U0001:88

―  The AFS control module detected CAN bus communication line (HS-CAN) malfunction 10 times continuously.

•  U0100:00

―  The AFS control module could not receive CAN signal from the PCM for 5 s or more.

•  U0131:00

―  The AFS control module could not receive CAN signal from the EPS control module for 5 s or more.

•  U0140:00

―  The AFS control module could not receive CAN signal from the front body control module (FBCM) for 5 s or more.

•  U0155:00

―  The 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 AFS control module

•  Malfunction in CAN communication line between EPS control module and AFS control module

•  Malfunction in CAN communication line between front body control module (FBCM) and AFS control module

•  Malfunction in CAN communication line between instrument cluster and AFS control module
