This standard is applicable to road vehicles, which are subject to the usage of the electronic vehicle interface to perform a Periodical Technical Inspection (ePTI).

The standard specifies the ePTI terminology, use cases and technical requirements in order to support the ePTI-relevant vehicle safety system(s) checks during the Periodical Technical Inspection via the electronic interface.

The standard specifies:

— Terminology;

— Communication establishment between the ePTI external test equipment and the vehicle's ePTI-relevant systems;

— Usage of a credentials based authentication and authorisation mechanism between the ePTI external test equipment and the vehicle;

— Protection against tampering of the defined ePTI methods;

— Definition of ePTI relevant use cases:

— ePTI external test equipment discovers available data identifier as specified in ISO 20730-3,

— ePTI external test equipment queries ePTI-relevant system’s information, including software identification, software integrity, current and/or stored values

— ePTI external test equipment activates ePTI-relevant system’s actuators or routines.

— Definition of ePTI-relevant technical requirements;

— ePTI external test equipment minimum requirements;

This standard is based on standardised diagnostic communication protocols.

This standard excludes:

— Process definitions for performing the PTI check,

— Process and data definitions for off-board data provision,

— Standardised data exchange formats,

— Validation and verification of vehicle safety systems according to vehicle manufacturer specifications.

This part of ISO 14229 specifies data link independent requirements of diagnostic services, which allow a diagnostic tester (client) to control diagnostic functions in an on-vehicle Electronic Control Unit (ECU, server) such as an electronic fuel injection, automatic gear box, anti-lock braking system, etc. connected to a serial data link embedded in a road vehicle.

It specifies generic services, which allow the diagnostic tester (client) to stop or to resume non-diagnostic message transmission on the data link.

This part of ISO 14229 does not apply to non-diagnostic message transmission on the vehicle's communication data link between two Electronic Control Units. However, this part of ISO 14229 does not restrict an in-vehicle on-board tester (client) implementation in an ECU in order to utilize the diagnostic services on the vehicle's communication data link to perform bidirectional diagnostic data exchange.

This part of ISO 14229 does not specify any implementation requirements.
