$215.00
This part of ISO 14230 specifies the requirements for the Keyword Protocol 2000 data link on which one or several on-vehicle Electronic Control Units are connected to an off-board tester in order to perform diagnostic functions.This part of ISO 14230 specifies the requirements of the implementation of the Diagnostic Services specified in ISO 14229, includingbyte-encoding and hexadecimal values for the service identifiers; byte-encoding for the parameters of the diagnostic service requests and responses; hexadecimal values for the standard parameters. The vehicle environment to which this part of ISO 14230 applies may consist of a single tester that may be temporarily connected to the on-vehicle diagnostic data link and several on-vehicle Electronic Control Units connected directly or indirectly (see figure 2).

ISO 14230-1:1999, Road vehicles -- Diagnostic systems -- Keyword protocol 2000 -- Part 1: Physical layer
$64.00
This part of ISO 14230 describes the physical layer, based on ISO 9141, on which the diagnostic services will be implemented. It is based on the physical layer described in ISO 9141-2, but expanded to allow for road vehicles with either 12 V or 24 V voltage supply.

Description:
The concentrations of vapor phase polycyclic aromatic hydrocarbons (PAHs) were measured at the Central Bus Station of Londrina, where only diesel-powered vehicles circulate. The samples were collected within a period of 24h for 14 consecutive days in January 2002. The semi-volatile PAHs were collected using a cartridge packed with XAD-2 resin, extracted under sonication and subsequently analyzed by gas chromatograph equipped with the flame ionization and mass spectrometer detectors (GC-FID and GC/MS). Ten PAH compounds were found (naphthalene, acenapthylene, acenapthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene and chrysene). The average concentrations ranged from 1.4+/-0.3ngm^-^3 for benzo(a)anthracene to 348.0+/-32.7ngm^-^3 for phenanthrene. The species that presented higher concentration were phenanthrene (348.0+/-32.7ngm^-^3), fluorene (140.2+/-17.3ngm^-^3) and naphthalene (97.7+/-10.3ngm^-^3). The PAHs with two and three rings were responsible by 90.2% of the total concentration among 10 PAHs. The concentrations of PAHs were lower on Sunday in comparison with the workdays, due to the reduction of bus traffic in the station. Correlations and principal component analysis with Varimax rotation were used to estimate the local PAH emission source profile originating from the diesel exhaust. The ratio PHEN/FLU of 2.5 calculated from the results is suggested as indication from diesel combustion exhaust.

ISO 14230-4:2000, Road vehicles -- Diagnostic systems -- Keyword Protocol 2000 -- Part 4: Requirements for emission-related systems
$42.00
This part of ISO 14230 specifies the requirements for the Keyword Protocol 2000 (KWP 2000) data link and connected vehicle and scan tool when used to comply with on-board diagnostic (OBD) requirements for emission-related test data.This part of ISO 14230 only specifies requirements relative to the Keyword Protocol 2000 for OBD purposes. Complete specification can be found in ISO 14230 parts 1 to 3 and in ISO 14229. ISO 14230-1, ISO 14230-2 and ISO 14230-3 are applicable for OBD purposes only as explicitly referenced in this part of ISO 14230. This title may contain less than 24 pages of technical content.
