1. Uvod
This document serves as the official instruction manual for ISO 14229:1998, an International Standard concerning diagnostic systems in road vehicles. It outlines the common requirements for diagnostic services, enabling a diagnostic tester to interact with on-vehicle electronic control units (ECUs).

2. Scope and Purpose
This International Standard specifies the common requirements for diagnostic services. These services facilitate a diagnostic tester's control over diagnostic functions within an on-vehicle electronic control unit (ECU). Examples of such ECUs include electronic fuel injection systems, automatic gearboxes, and anti-lock braking systems. The connection for these diagnostic functions is established via a serial data link embedded within the road vehicle.
Furthermore, this standard defines generic services that allow the diagnostic tester to either stop or resume the transmission of non-diagnostic messages on the data link. This capability is crucial for managing data flow during diagnostic operations.
3. Izključitve in omejitve
It is important to note that this International Standard has specific exclusions:
- It does not apply to non-diagnostic message transmission itself.
- It does not apply to the use of the communication data link between two electronic control units.
- It does not specify implementation requirements.
- It does not define numerical values for services and parameters.
- It does not specify requirements for the communication services themselves.
The focus is strictly on the diagnostic services specification, not the underlying communication protocols or specific implementation details.
4. Applicability of Vehicle Diagnostic Architecture
The vehicle diagnostic architecture described by this International Standard is applicable in two primary scenarios:
- Single Tester Connection: This standard applies to a single diagnostic tester that may be temporarily or permanently connected to the on-vehicle diagnostic data link.
- Multiple Electronic Control Units: It also applies to several on-vehicle electronic control units that are connected either directly or indirectly to the diagnostic system.
This ensures a standardized approach to diagnostics across various vehicle configurations.
