Enhanced E/E Diagnostic Test Modes

CURRENT
J2190_200810
This SAE Recommended Practice describes the implementation of Enhanced Diagnostic Test Modes, which are intended to supplement the legislated Diagnostic Test Modes defined in SAE J1979. Modes are defined for access to emission related test data beyond what is included in SAE J1979, and for non-emission related data. This document describes the data byte values for diagnostic messages transmitted between diagnostic test equipment, either on-vehicle or off-vehicle, and vehicle electronic control modules. No distinction is made between test modes for emission related and non-emission related diagnostics. These messages can be used with a diagnostic serial data link such as described in SAE J1850 or ISO 9141-2. For each test mode, this document includes a functional description of the test mode, request and report message data byte content, and an example if useful for clarification.

J2054_199011
This SAE Information Report describes the diagnostic data communications required for implementation of a set of diagnostic test modes for all electronic systems on the vehicle's serial data link. These test modes can be used by off-board test equipment for both service and assembly plant testing. The goal of this document is to provide standard methods to perform common functions for all electronic systems. This standard set of procedures will aid development, production, and field service of those systems. Use of the standard data communications in this specification will potentially result in the following benefits: This specification includes:

J2037_199011
The utilities defined for J2037 are designed to facilitate manufacturing and service diagnosis requirements. Definition of the capability includes definition of standard messages and the dialogue necessary to provide the capability. The standard messages will be distinguished by the contents of the first data byte which specifies the diagnostic operation. Note that some vehicle applications will not require the implementation of all the defined diagnostic capabilities, and consequently, these applications will not support all message modes.

Translation Quality Metric

J2450_200508
This SAE Standard is applicable to translations of automotive service information into any target language. The metric may be applied regardless of the source language or the method of translation (i.e., human translation, computer assisted translation or machine translation). Note that the current version of the metric does not measure errors in style, making it unsuitable for evaluations of material in which style is important (e.g., owner's manuals or marketing literature). The metric can be expanded to accommodate style and other requirements of particular new media.

E/E DATA LINK SECURITY

J2186_199610
This SAE Recommended Practice establishes a uniform practice for protecting vehicle components from "unauthorized" access through a vehicle data link connector (DLC). The document defines a security system for motor vehicle and tool manufacturers. It will provide flexibility to tailor systems to the security needs of the vehicle manufacturer. The vehicle modules addressed are those that are capable of having solid state memory contents accessed or altered through the data link connector. Improper memory content alteration could potentially damage the electronics or other vehicle modules; risk the vehicle compliance to government legislated requirements; or risk the vehicle manufacturer's security interests. This document does not imply that other security measures are not required nor possible.

This SAE Recommended Practice establishes a uniform practice for protecting vehicle modules from "unauthorized" intrusion through a vehicle diagnostic data communication link. The security system represents a recommendation for motor vehicle manufacturers and provides flexibility for them to tailor their system to their specific needs. The vehicle modules addressed are those that are capable of having solid-state memory contents altered external to the electronic module through a diagnostic data communication link. Improper memory content alteration could potentially damage the electronics or other vehicle modules; risk the vehicle compliance to government legislated requirements; or risk the vehicle manufacturer's security interests. This document is intended to meet the "tampering protection" provisions of California Air Resources Board OBD II regulations and does not imply that other security measures are not required nor possible.

This document should be used in conjunction with SAE J2534-2 in order to enhance an SAE J2534 interface to also provide the capability to program ECUs with GM UART. SAE J2534-1 includes requirements for an interface that can be used to program certain emission-related Electronic Control Units (ECUs) as required by U.S. regulations, and SAE J2534-2 defines enhanced functionality required to program additional ECUs not mandated by current U.S. regulations. The purpose of this document is to specify the requirements necessary to implement GM UART in an enhanced SAE J2534 interface intended for use by independent automotive service facilities to program GM UART ECUs in General Motors vehicles.

SAE J2534-1_0500 defines the pass-thru interface requirements for the reprogramming of emission related control modules. The SAE J2534-2/X_0500 document set adds extensions to the SAE J2534-1_0500 API (version 05.00) specification so that the API can be used for features not covered in the SAE J2534-1_0500 specification. Together, these features provide a comprehensive framework for a common standard, to protect the software investment of the vehicle OEMs and scan tool manufacturers. There is no required for an SAE J2534-2/X_0500 pass-thru interface to be fully compliant with SAE J2534-1_0500. SAE J2534-2/X_0500 interfaces can implement some or all of the features specified in the SAE J2534-2/X_0500 document set. This document must be used in conjunction with the SAE J2534-2/RE_0500 document.

SAE J1979-3 describes the communication between the zero emissions propulsion systems and test equipment required by government regulations. Standardization regulations require passenger cars and light-, medium-, and heavy-duty trucks to support a minimum set of diagnostic information to external (off-board) “generic” test equipment. To achieve this, SAE J1979-3 is based on the Open Systems Interconnection (OSI) Basic Refer to Model in accordance with ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers.

This SAE Recommended Practice describes a standardized interface that connects between a standard personal computer (PC) and vehicle.The purpose of this interface is to enable the reprogramming of emission-related control modules, in 2004 and later model year vehicles. The interface shall consist of the necessary hardware and/or software to support the requirements defined in this document. It is expected that vehicle manufacturers will provide the software application that will control the pass-thru interface, to perform the actual reprogramming. The goal of this document is to ensure that reprogramming software from any vehicle manufacturer is compatible with interface supplied by any tool manufacturer. A common interface for all vehicle manufacturers reduces the tool costs for aftermarket garages, while allowing each vehicle manufacturer to control the programming sequence for the electronic control units (ECUs) in their vehicles.

SAE J2534-1 defines a standard vehicle network interface that can be used to reprogram emission-related control modules. However, there is a need to support vehicles prior to the 2004 model year, as well as non-emission related control modules. The SAE J2534-2 document meets these needs by detailing extensions to an SAE J2534-1 specification. It is not required for an interface to be fully compliant with SAE J2534-1 specification to implement some of the features specified in this document. Together, these extensions provide the framework for a common interface to protect the software investment of the Vehicle OEMs and Scan Tool manufacturers. Only the optional features will be described by this document and are based on the December 2004 publication of SAE J2534-1.
