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

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

• U0100:00

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

• U0131:00

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

• U0140:00

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

• U0155:00

• AFS control module could not receive the CAN signal from the instrument cluster for 5 s or more.

Fail-safe function

• 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
