OBD- II Drive Cycle




DIAGNOSTIC FUNCTION

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.

NOTE:
Drive cycle patterns are not established for Vehicle speed sensor monitor (DTC P0500), Power steering pressure switch monitor (P0551), and Fuel level sensor monitor (DTC P0461, 2066 [AWD]).
Please reference the M.U.T. data list to judge whether these monitor items are normal.
