Description
0 × 05
Request oxygen sensor monitoring test results
Service 0 × 05 is not supported for ISO 15765-4. The functionality of Service
0 × 05 is implemented in Service 0 × 06
0 × 06
Request on-board monitoring test results for specific monitored systems
The purpose of this service is to allow access to the results for on-board diag-
nostic monitoring tests of specific components/systems that are continuously
monitored (e.g. misfire monitoring for gasoline vehicles) and non-continuously
monitored (e.g. catalyst system)
0 × 07
Request emission-related diagnostic trouble codes detected during current or last
completed driving cycle
The purpose of this service is to enable the external test equipment to obtain
“pending” diagnostic trouble codes detected during current or last completed
driving cycle for emission-related components/systems. Service 0 × 07 is
required for all DTCs and is independent of Service 0 × 03. The intended use of
this data is to assist the service technician after a vehicle repair, and after clear-
ing diagnostic information, by reporting test results after a single driving cycle.
If the test failed during the driving cycle, the DTC associated with that test shall
be reported. Test results reported by this service do not necessarily indicate a
faulty component/system. If test results indicate a failure after additional driv-
ing, then the MIL will be illuminated and a DTC will be set and reported with
Service 0 × 03, indicating a faulty component/system. This service can always be
used to request the results of the latest test, independent of the setting of a DTC
0 × 08
Request control of on-board system, test or component
The purpose of this service is to enable the external test equipment to control the
operation of an on-board system, test or component
The data bytes will be specified, if necessary, for each test ID in SAE J1979-DA,
and will be unique for each test ID
Possible uses for these data bytes in the request message are as follows:
• Turn on-board system/test/component ON
• Turn on-board system/test/component OFF
• Cycle on-board system/test/component for 'n' seconds
Possible uses for these data bytes in the response message are as follows:
• Report system status
• Report test results
0 × 09
Request vehicle information
The purpose of this service is to enable the external test equipment to request
vehicle-specific vehicle information such as vehicle identification number
(VIN) and calibration IDs. Some of this information may be required by regu-
lations and some may be desirable to be reported in a standard format if sup-
ported by the vehicle manufacturer. InfoTypes are defined in SAE J1979-DA
0 × 0A
Request emission-related diagnostic trouble codes with permanent status
The purpose of this service is to enable the external test equipment to obtain all
DTCs with “permanent DTC” status. These are DTCs that are “confirmed”
and are retained in the non-volatile memory of the server until the appropriate
monitor for each DTC has determined that the malfunction is no longer present
and is not commanding the MIL on
Service 0 × 0A is required for all emission-related DTCs. The intended use of this
data is to prevent vehicles from passing an in-use inspection simply by discon-
necting the battery or clearing DTCs with a scan tool prior to the inspection. The
presence of permanent DTCs at an inspection without the MIL illuminated is an
indication that a proper repair was not verified by the on-board monitoring system
