OBD-II Drive Cycle

OBD-II DRIVE CYCLE

All kinds of diagnostic trouble codes (DTCs) can be monitored by carrying out a short drive according to the following 23 drive cycle patterns. In other words, doing such a drive regenerates any kind of trouble which involves illuminating the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) and verifies the repair procedure has been eliminated [the trouble the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) is no longer illuminated].

CAUTION: Two technicians should always be in the vehicle when carrying out a test.

NOTE:
- Check that the diagnosis trouble code (DTC) is not output before driving the OBD-II drive cycle. Erase the DTC if it has been output.
- Drive cycle patterns are not established for Power steering pressure switch monitor (P0551), and Fuel level sensor monitor (DTC P0461, P2066 ). Please reference the M.U.T. data list to judge whether these monitor items are normal.
