Question

What information does Mode $06 of the OBD II standard provide?

Accepted Answer

Mode $06 of the OBD II standard provides access to on-board diagnostic test results for non-continuously monitored systems. Unlike continuously monitored systems that trigger a Diagnostic Trouble Code (DTC) immediately upon detecting a fault, non-continuously monitored systems are tested less frequently. Mode $06 data allows technicians to view the results of these tests, including the minimum and maximum acceptable values, the actual measured values, and the test IDs. This information can be used to identify potential problems before they trigger a DTC and illuminate the Malfunction Indicator Lamp (MIL). For example, Mode $06 can provide data on the performance of the catalytic converter, the evaporative emissions system, and other components that are not constantly monitored. Accessing Mode $06 data requires a scan tool that supports this function, and interpreting the data requires a good understanding of the specific OBD II system and the vehicle&#x27;s emission control components. It provides a deeper level of diagnostic information than standard DTCs alone.
