Permanently or Semi-Permanently Installed Diagnostic Communication Devices
The scope of the document is to define communication best practices in order to minimize problems for the vehicle owner when installing equipment which has a permanently or semi-permanently diagnostic communication device connected to the SAE J1962 connector or hardwired directly to the in-vehicle network.
SAE J3005 is being published as a new document as guidance for Remote I/M programs Portable Emission Measurement Systems (PEMS), GPS, Wireless-LAN or Bluetooth interfaces and insurance devices. The SAE J3005 devices are not intended to be used for SAE J1699-3 vehicle validation testing. The document focuses on OBD mandated communication protocols defined in SAE J1979.
It is not the purpose of this document to preclude the use of non SAE J1979 proprietary protocols, PIDs, or connector pins used by vehicle manufacturers. Device manufacturers should check with vehicle manufacturer guidelines before using proprietary information.
