Malfunction Codes In Case Of Disruption Of Can Communication; Engine Equipment/Emission Control Device Can Line (250 K) - Hino Motors HINO 155 series Workshop Manual

MALFUNCTION CODES IN CASE OF DISRUPTION OF CAN COMMUNICATION

Since the CAN communication line is configured as described below, more than one malfunction code may occur depend-
ing on the faulty area of the circuit.
For single failure
• The system itself is suspected of being faulty due to the broken harness or connector or supply circuit failure of the CAN
communication circuit for each actuator and controller.
