16、nization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establis
17、hed has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization
18、. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. P
19、ublication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such pate
20、nt rights. ISO 15031-5 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronical equipment. ISO 15031 consists of the following parts, under the general title Road vehicles Communication between vehicle and external equipment for emissions-related d

22、 Part 7: Data link security -,-,- ISO 15031-5:2006(E) ISO 2006 All rights reserved v Introduction ISO 15031 consists of a number of parts which, taken together, provide a coherent self-consistent set of specifications to facilitate emissions-related diagnostics. Parts 2 through 7 are based on SAE re
23、commended practices. This part is based on SAE J1979 SEP97 (E/E Diagnostic Test Modes). ISO 15031-1 provides an introduction to the series of International Standards. This part of ISO 15031 is based on the Open Systems Interconnection (OSI) Basic Reference Model in accordance with ISO/IEC 7498 and I
24、SO/IEC 10731, which structures communication systems into seven layers as shown in the table below.

27、and functionally addressed request/response messages required to be supported by motor vehicles and external test equipment for diagnostic purposes which pertain to motor vehicle emission-related data. Any external test equipment meeting the requirements of ISO 15031-4 use these messages to retrieve
28、 emissions-related information from the vehicle. Each section of this part of ISO 15031, which specifies additional detail to existing sections of ISO 9141-2, ISO 14230-4, SAE J1850, and ISO 15765-4 supersede those specifications. NOTE This part of ISO 15031 provides the mechanism to satisfy the req
29、uirements included in the country-specific regulations and not all capabilities included in this document are required by the country-specific regulations. This part of ISO 15031 also is not considered a final authority for interpretation of the regulations, so readers should determine the applicabi
30、lity of capabilities defined in this document for their specific needs. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、0: MAY2001,Class B Data Communications Network Interface 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 15031-2 and the following apply. 3.1 absolute throttle position sensor value intended to represent the throttle opening NOTE For systems where th
37、e output is proportional to the input voltage, this value is the percent of maximum input signal. For systems where the output is inversely proportional to the input voltage, this value is 100 % minus the percent of maximum input signal. Throttle position at idle usually indicates greater than 0 %,
38、and throttle position at wide open throttle usually indicates less than 100 %. 3.2 bank specific group of cylinders sharing a common control sensor, bank 1 always containing cylinder number 1, bank 2 the opposite bank NOTE If there is only one bank, bank #1 DTCs is used, and the word bank may be omi
39、tted. With a single “bank” system utilising multiple sensors, bank #1 DTCs is used identifying the sensors as #1, #2, #3 in order as they move further away from the cylinder(s). 3.3 base fuel schedule the fuel calibration schedule programmed into the Powertrain Control Module or PROM when manufactur
40、ed or when updated by some off-board source, prior to any learned on-board correction 3.4 Calculated Load Value for spark ignition engines, typically an indication of the current airflow divided by peak airflow at wide open throttle as a function of rpm, where airflow is corrected for altitude and a
41、mbient temperature NOTE 1 This definition provides a unit-less number, and provides the service technician with an indication of the percent engine capacity that is being used. NOTE 2 For diesel applications, the calculated load value shall be determined by substituting fuelflow in place of airflow
42、in the calculation. 3.5 client function that is part of the tester and that makes use of the diagnostic services NOTE A tester normally makes use of other functions such as data base management, specific interpretation, man-machine interface. 3.6 continuous monitoring sampling at a rate no less than
43、 two samples per second ISO 15031-5:2006(E) ISO 2006 All rights reserved 3 3.7 convention Cvt column integrated in each message table which marks each parameter included NOTE The following conventions are used: C = Conditional: the parameter marked “C” in a request/response message is present only u
44、nder a condition specified in the bottom row of the message table. M = Mandatory: the parameter marked “M” in a request/response message table is always present. U = User optional: the parameter marked “U” in a request/response message table is or is not supplied, depending on dynamic usage by the m
45、anufacturer. The convention recommends a mnemonic, which might be used for implementation. In no case is the specified mnemonic a mandatory requirement for any implementation. 3.8 Electronic Control Unit ECU generic term for any electronic control unit 3.9 Fuel Trim FT feedback adjustments to the ba
46、se fuel schedule NOTE Short-term fuel trim refers to dynamic or instantaneous adjustments. Long-term fuel trim refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. These long-term adjustments compensate for vehicle differences and gradual changes
47、 that occur over time. 3.10 negative numbers signed binary, the most significant bit (MSB) of the binary number used to indicate positive (0) / negative (1) NOTE 1 2s complement: negative numbers are represented by complementing the binary number and then adding 1. EXAMPLE 0,99 = 8001 hex = 1000 000
48、0 0000 0001 binary 0 = 0000 hex = 0000 0000 0000 0000 binary + 0,99 = 7FFF hex = 0111 1111 1111 1111 binary NOTE 2 ( 0,99) + (+ 0,99) = 0. 3.11 number expressed by this symbol “#” 3.12 P2, P3 timing parameter application timing parameters for the ECU(s) and the external test equipment 3.13 server function that is part of an electronic control unit that provides the diagnostic services NOTE This part of ISO 15031 differentiates between the server (i.e. the function) and the electronic control unit so that this document remains independ
