Hazard
In the emissions control system, the control computer's fault diagnosis program is inappropriate, which may result in failure to properly diagnose faults or display warning indicators in the event of a malfunction. Consequently, the onboard diagnostic device (J-OBD2 for diesel heavy vehicles) does not satisfy the technical standards specified in Regulation 31, Detailed Notification Article 41, Attachment 48 of the safety standards.
