WIP Standard
2014-01-10
The intent of this standard is to establish a framework to assure that all evaporators for R-744 and R-1234yf mobile air conditioning (MAC) systems meet appropriate testing and labeling requirements. SAE J639 requires vehicle manufacturers to perform assessments to minimize reasonable risks in production MAC systems. The evaporator (as designed and manufactured) shall be part of that risk assessment and it is the responsibility of the vehicle manufacturer to assure all relevant aspects of the evaporator are included. It is the responsibility of all vehicle or evaporator manufacturers to comply with the standards of this document at a minimum. (Substitution of specific test procedures by vehicle manufactures that correlate well to field return data is acceptable.) As appropriate, this standard can be used as a guide to support risk assessments. With regard to certification, most vehicle manufacturers have established formal production part approval processes (PPAP) where compliance certification is established and formally documented.

This Standard describes methods to understand the risks associated with vehicle mobile air conditioning [MAC] systems in all aspects of a vehicle’s lifecycle including design, production, assembly, operation and end of life. Information for input to the risk assessment is provided in the Appendices of this document. This information should not be considered to be complete, but only a reference of some of the data needed for a complete analysis of the risk associated with the use of refrigerants in MAC systems.

This Standard is restricted to refrigeration circuits that provide air-conditioning for the passenger compartments of passenger and commercial vehicles. This Standard includes analytical and physical test procedures to evaluate concentration inside the passenger compartment. In the early phases of vehicle evaluation, usage of the analytical approach may be sufficient without performing physical tests. The physical test procedure involves releasing refrigerant from an external source to a location adjacent to the evaporator core (inside the HVAC-Module). An apparatus is used to provide a repeatable, calibrated leak rate. If the system has multiple evaporators, leakage could be simulated at any of the evaporator locations. This standard gives detail information on the techniques for measuring R-744 [CO2] and R-1234yf [HFO-1234yf], but the general techniques described here can be used for other refrigerants as well.

The reader of specifications sometimes needs some help understanding the format of an AMS and reasoning behind certain usage of terms. The scope of this AIR is to explain the functions of the various sections of the specifications, why some of the terms in AMS specifications are used, and how the specification system works. After the introduction (Section 3 of this document), the topics are presented in the order they usually appear in specifications.

Modern Automotive Technology details the construction, operation, diagnosis, service, and repair of late-model automobiles and light trucks. This comprehensive book uses a building-block approach that starts with the fundamental principles of system operation and progresses gradually to complex diagnostic and service procedures. Short sentences, concise definitions, and thousands of color illustrations help readers learn quickly and easily. The new edition of Modern Automotive Technology provides coverage of the latest developments in the automotive field and is correlated to the 2012 NATEF Task List. A new Fundamentals of Electricity and Electronics section provides the background needed to troubleshoot and repair the complex electrical/electronic systems found on today’s vehicles. Updated information on hybrid drive systems has been integrated throughout the book, and a new hybrid drive system service chapter details the diagnosis and repair of these important systems.

This specification establishes the requirements for etch inspection of bare high strength low alloy steel parts having tensile strength of 180 ksi (1241 MPa) and higher and of carburized parts to detect overheating caused by abusive machining or grinding in the heat treated condition, and to detect localized discontinuous carburization. This process is not applicable to surface hardened steels produced by nitriding or carbonitriding. This process may remove 0.0001 to 0.0005 inch (2.5 to 12.7 micrometers) from the surface of the part.

A vehicle electronic control unit consists of various high side power stages for driving different loads. Common faults such power stages experience are Short Circuit to Battery (SCB), Short Circuit to Ground (SCG) and Open Load (OL). These faults can occur during either on-state or off-state of power stage output. It is essential to diagnose a fault such as SCB during switch off-state, SCG during switch on-state and OL during both on and off-state of the switch in order to avoid system malfunction, power-stage damage etc. A high-side power-stage mainly consists of a switching power MOSFET and its driver section. Quite often the semiconductor manufacturers provide diagnostic information through a digital status (ST) output. A logic low level on the ST pin indicates a fault. The limitation the ST signal is its inability to distinguish faults SCG, SCB and OL. For high-side switches (HSS), to overcome these drawbacks, there is a need of proper diagnosing technique. The diagnosis technique should address i Detect a fault of power stage.ii Clearly distinguish the kind of fault.

SAE J1939-73 Diagnostics Application Layer defines the SAE J1939 messages to accomplish diagnostic services and identifies the diagnostic connector to be used for the vehicle service tool interface. Diagnostic messages (DMs) provide the utility needed when the vehicle is being repaired. Diagnostic messages are also used during vehicle operation by the networked electronic control modules to allow them to report diagnostic information and self-compensate as appropriate, based on information received. Diagnostic messages include services such as periodically broadcasting active diagnostic trouble codes, identifying operator diagnostic lamp status, reading or clearing diagnostic trouble codes, reading or writing control module memory, providing a security function, stopping/starting message broadcasts, reporting diagnostic readiness, monitoring engine parametric data, etc. California, EPA, or EU regulated OBD requirements are satisfied with a subset of the specified connector and the defined messages.
