6、 BritishStandard has been prepared under the direction of the Automobile Standards Committee and is identical with ISO8093:1985 “Road vehicles Diagnostic testing of electronic systems” published by the International Organization for Standardization (ISO). Terminology and conventions. The text of the

7、 International Standard has been approved as suitable for publication as a BritishStandard without deviation. Some terminology and certain conventions are not identical with those used in BritishStandards; attention is drawn especially to the following. The comma has been used as a decimal marker. I

8、n BritishStandards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “BritishStandard”.

This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicat

11、ed in the amendment table on the inside front cover.BSAU206-4:1986 BSI 02-2000 1 1 Scope This International Standard defines diagnostic provisions applicable to electronic systems in road vehicles. 2 Field of application This International Standard applies to electronic systems including electronic

12、control modules, associated input sensors, output actuators and indicators. The measurement ranges specified exclude certain devices for which specific test equipment is required. It does not apply to those systems which have built-in diagnostic capabilities and do not require compatibility with off

13、-board equipment. 3 Reference ISO4092, Road vehicles Diagnostic systems for motor vehicles Vocabulary. 4 Definitions For the purpose of this International Standard, the definitions of ISO4092apply. 5 General requirements Where the functions to be tested are specified by the vehicle manufacturer, the

14、 test shall be carried out in accordance with the manufacturers instructions, which shall take into account the principles of5.1 to5.3. 5.1 Accessibility of electronic systems The electronic components of the system to be tested shall be designed so that it is possible to make the necessary connecti

15、ons to the test equipment. Relevant operational circuits shall be easily accessible and identifiable for test purposes. This may be made possible through the input and output connectors or by special connector(s). 5.2 Simulation of vehicle generated input signals If output signals have to be observe

16、d under specific operating conditions, the possibility of substituting or overriding input signals is required. 5.3 Signals in output lines Consideration should be given to the fact that, in some installations, output lines may also serve as input lines, and in that case shall conform to5.2.BSAU206-

17、4:1986 2 BSI 02-2000 6 Requirements for the measuring equipment Table 6.1 Resolution Resolution is taken to mean the smallest change of parameter value resulting in a discernible display change (which requires a minimum display of3digits). In the case of analogue displays,1/5 of the scale division v

18、alue is understood to be the resolution. 6.2 Accuracy The figures given in the column accuracy (seethe Table) allow the worst case error to be calculated. Measuring errors are caused by different factors. There are constant errors over the full measuring range and their values can be specified as a

19、percentage of the full scale value. There are also errors proportional to the measured values.
