ISO 14229:2006
Scope
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 (server) such as an electronic
fuel injection, automatic gear box, anti-lock braking system, etc. connected on a serial data link embedded in a
road vehicle. It specifies generic services which allow the diagnostic tester (client) to stop or to resume nondiagnostic
message transmission on the data link. ISO 14229 does not apply to non-diagnostic message
transmission or to use of the communication data link between two Electronic Control Units. It does not
specify any implementation requirements.
The vehicle diagnostic architecture of ISO 14229 applies to:
-- a single tester (client) that may be temporarily or permanently connected to the on-vehicle diagnostic data
link; and
-- several on-vehicle Electronic Control Units (servers) connected directly or indirectly.
