This document supersedes SAE J1962 200204, and is technically equivalent to ISO/DIS 15031-3: December 14, 2001. This document is intended to satisfy the requirements of an OBD connector as required by U.S. On-Board Diagnostic (OBD) regulations. The diagnostic connection specified in this document consists of two mating connectors, the vehicle connector and the external test equipment connector. This document specifies: a The functional requirements for the vehicle connector. These functional requirements are separated into four principal areas: connector location/access, connector design, connector contact allocation, and electrical requirements for connector and related electrical circuits, b The functional requirements for the external test equipment connector. These functional requirements are separated into three principal areas: connector design, connector contact allocation, and electrical requirements for connector and related electrical circuits.
This specification describes the design relative to assembly force and hand clearance guidelines for conventional hand-plug, mechanical assist, twist lock, and high voltage electrical connectors, as well as Connector Position Assurances (CPAs). The minimum values associated with this design guide need to be evaluated against other critical characteristics that impact quality, efficiency, and other traits of assembly feasibility. Non-routine repair tasks do not apply to this specification. In addition, ergonomic risk factors may be present in other subtasks related to connector mating - such as lifting the harness or manipulating it into position. These risk factors are not discussed within SAE/USCAR-25. All possible designs and applications could not be anticipated in creating these guidelines. Where there are questions of adherence to this specification, such as use of an “off-the-shelf” design, always consult the responsible Ergonomics Department.
This document is an SAE Standard and covers the requirements for determining the immunity characteristics of automotive electronic equipment, subsystems, and systems to EM energy injected individually onto each lead. This test may be used over the frequency range of 15 Hz to 250 kHz. The method is applicable to all input, output, and power leads. The method is particularly useful in evaluating DUTs with acoustic or visible display functions.
The scope of this Recommended Practice encompasses the range of environments which influence the performance and reliability of the electronic equipment designed for heavy duty on and off road vehicles, as well as any appropriate stationary applications which also use these vehicle derived components.

This part of SAE J1113 specifies the direct RF power injection test method and procedure for testing electromagnetic immunity of electronic components for passenger cars and commercial vehicles. The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous, narrowband conducted RF energy. This test method is applicable to all DUT leads except the RF reference ground. The test provides differential mode excitation to the DUT. Immunity measurements of complete vehicles are generally only possible by the vehicle manufacturer. The reasons, for example, are high costs of a large absorber-lined chamber, preserving the secrecy of prototypes or the large number of different vehicle models. Therefore, for research, development, and quality control, a laboratory measuring method for components shall be applied by the manufacturer. This method is suitable over the frequency range of 250 kHz to 400 MHz. This direct RF power injection test is particularly effective

SAE JA6097 (“Using a System Reliability Model to Optimize Maintenance”) shows how to determine which maintenance to perform on a system when that system requires corrective maintenance to achieve the lowest long-term operating cost. While this document may focus on applications to Jet Engines and Aircraft, this methodology could be applied to nearly any type of system. However, it would be most effective for systems that are tightly integrated, where a failure in any part of the system causes the entire system to go off-line, and the process of accessing a failed component can require additional maintenance on other unrelated components.

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.

The importance of reliability in design engineering has significantly grown since the early 1960’s. Competition has been a primary driver in this growth. The three realities of competition today are: world class quality and reliability, cost-effectiveness, and fast time-to-market. Formerly, companies could effectively compete if they could achieve at least two of these features in their products and product development processes, often at the expense of the third. However, customers today, whether military, aerospace, or commercial, have been sensitized to a higher level of expectation and demand products that are highly reliable, yet affordable. Product development practices are shifting in response to this higher level of expectation. Today, there is seldom time, or necessary resources to extensively test, analyze, and fix to achieve high quality and reliability. It is also true that the rapid growth in technology prevents the accumulation of historical data on the field performance
