This SAE Standard provides a general method for defining the function performance status classification for the functions of automotive electronic devices upon application of the test conditions specified as described in appropriate EMC test standards (for example, the SAE J1113 series and the SAE J551 series). Testing of devices could be performed either on or off vehicles. Appropriate test signal and methods, region of performance, and test signal severity level would have to be specified in the individual cases.
The document is revised to demonstrate the concept with a "single class" functional status with application of multiple categories of functions. Changes were also made to the terminology and examples to harmonize with the similar concept in ISO 7637, ISO 11451, ISO 11452 and ISO 16750.
