How did onboard diagnostics II come to be?

When Onboard Diagnostics II was first conceived as a means of monitoring vehicle emissions, it was obvious there would be a lot of information to keep track of. The Society of Automotive Engineers (SAE) developed guidelines for managing all of this information and came up with a list of “diagnostic modes” that scan tools would have to provide.

What can mode 06 data be used for?

The Mode 06 data can be used to verify repairs and to make sure there aren’t any other “hidden” faults waiting to turn on the MIL light after a customer leaves your shop.

What’s the difference between Tid and mid for monitor identification?

The first is the Test Identification (TID) that indicates the monitor test, and the second is the Component Identification (CID) that identifies the sensor or other component that is being tested. After that come the actual test results. On CAN compatible vehicles, the TID is now called MID for Monitor Identification.

What is mode 06 in total car diagnostics?

The bottom line is that Mode $06 is an advanced diagnostic mode that allows technicians to peer deep into the inner workings of the OBD2 system. It requires a OBD2 scanner that can access and display the TID and CID test results, and an understanding of the data that is displayed. Can read more about Mode 06 here.

Where can I find information on mode 06?

Mode 06 information on other vehicle manufacturers can usually be found by searching their service websites. These sites, which include all their OBD II related service information, can be accessed via the internet for fees ranging from free to about $25 per day. For a complete list of OEM websites, go to www.nastf.org.

How to check for DTCs in mode 06?

When you plug in a scan tool, you don’t necessarily see all of these things listed as operating modes. They are usually labeled by their function rather than mode number. So if you want to check for any DTCs, you choose “Check DTCs” on the scan tool menu. If you want to clear codes, you choose “Clear Codes” on the scan tool menu.

What does mode 06 mean on OBD diagnostics?

Mode 06 data is typically displayed in three columns. The first column is the “TID” (Test identification) that indicates what system monitor is involved. The second column is the “CID” (Component identification), which corresponds to the component being tested and its test value.
