ISO 26021-1:2022 PDF

This document is applicable to road vehicles, where the electronic vehicle interface of the diagnostic link connector (DLC) is used to perform an end-of-life (EoL) activation of in-vehicle pyrotechnic devices. Apart from actual removal, this is the method to assure that no pyrotechnic substances are left in an EoL vehicle. On-board activation is an effective and safe method.

This document describes use cases and specifies technical requirements in order to support the end-of-life activation of in-vehicle pyrotechnic devices via the electronic communication interface. This document references the ISO°14229 series unified diagnostic services implemented on diagnostic communication over controller area network (DoCAN) and Internet Protocol (DoIP) along with the required provision of data definitions.

This document comprises:
— terminology definitions;
— definition of end-of-life activation of in-vehicle pyrotechnic devices relevant use cases;
— requirements for the establishment of communication between the pyrotechnic device deployment tool (PDT) and the vehicle's pyrotechnic control unit(s) (PCU(s));
— requirements for the optional usage of a credentials-based authentication and authorisation mechanism between the PDT and the vehicle;
— requirements for the protection against tampering of the defined end-of-life activation of in-vehicle pyrotechnic devices;
— PCU-relevant technical requirements.

PDT-relevant requirements are specified in a test equipment-specific standard with PDT-specific requirements.
