Description

U0001:88

• Unit communication error (HS-CAN)

U0100:00

• Communication error with PCM

U0140:00

• Communication error with BCM

U0155:00

• Communication error with instrument cluster

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 BCM 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 BCM and auto leveling control module

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