What is OBD Mode 6 Data (On-board Test Results)?
It can reveal problems before a warning light appears. It includes misfire counts on many vehicles. Values and identifiers vary by manufacturer. Technicians use it to check whether a repair has fixed a borderline fault, such as a catalytic converter close to its limit. Some manufacturers publish the meaning of their test IDs in service information.
How it works
The control unit stores test values and limits after each monitor runs.
