Product Code:SAE J1939/84
Title:OBD Communications Compliance Test Cases for Heavy Duty Components and Vehicles
Issuing Committee:Truck Bus Control And Communications Network Committee
Scope: The purpose of this Recommended Practice is to verify that vehicles and/or components are capable of communicating arequired set of information, in accordance with the diagnostic test messages specified in SAE J1939-73, to fulfill the offboarddiagnostic tool interface requirements contained in the government regulations cited below.This document describes the tests, test methods, and results for verifying diagnostics communication from an off boarddiagnostic tool (i.e., scan tool) to a vehicle and/or component. SAE members have generated this document to serve as aguide for testing vehicles for compliance with ARB and other requirements for emissions-related on-board diagnostic(OBD) functions for heavy duty engines used in medium and heavy duty vehicles.
