Organization: ISO
Publication Date: 1 December 2006
Status: inactive
Page Count: 300
ICS Code (Diagnostic, maintenance and test equipment): 43.180
scope:

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 (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 non-diagnostic message transmission on the data link. This part of 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 this part 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.

- For vehicle 1, the servers are connected over an internal data link and indirectly connected to the diagnostic data link through a gateway. This part of ISO 14229 applies to the diagnostic communications over the diagnostic data link; the diagnostic communications over the internal data link may conform to this part of ISO 14229 or to another protocol.

- For vehicle 2, the servers are directly connected to the diagnostic data link.

- For vehicle 3, the servers are directly connected to the diagnostic data link through a gateway (same as vehicle 2) and vehicle 4 connects its server/gateway directly to the vehicle 3 server/gateway.
