ISO 15031-1 provide
18、s an introduction to the series of International Standards. ISO 15031-2 through ISO 15031-7 are based on Society of Automative Engineers (SAE) recommended practices. This part of ISO 15031 is based on SAE J2186:1996, E/E Data Link Security.The ISO 15031 document set includes the communication betwee
19、n the vehicles On-Board Diagnostics (OBD) systems and test equipment implemented across vehicles within the scope of the legislated emissions-related OBD.To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model in accordance with ISO/IEC 7498-1 and ISO/IEC 10731,
20、which structures communication systems into seven layers. When mapped on this model, the services specified by ISO 15031 are broken into the following: Diagnostic services (layer 7), specified in: ISO 15031-5 (emissions-related OBD); ISO 27145-3 (WWH-OBD); Presentation layer (layer 6), specified in:

These security measures off
40、er vehicle manufacturers the flexibility to tailor their security to their own specific needs and do not exclude other, additional measures.This part of ISO 15031 applies to vehicle modules whose solid-state memory contents are able to be altered from outside the electronic module through a diagnost

Such alteration could potentially damage a vehicles electronics or other components, placing at risk its compliance with government legislation or the vehicle manufacturers interests in respect of security.2 Normative referencesThe following documents, in whole or in part
