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 Power steering pressure switch monitor (P0551), and Fuel
level sensor monitor (DTC P0461, P2066 <AWD>). Please reference the M.U.T. data list to judge whether
these monitor items are normal.

conditions
• Engine coolant temperature: More than 76°C (140°F)
• Condition of CVT: Selector lever "D" range
Test
procedure
1. Start the engine with all the accessories switched OFF.
2. Drive the vehicle for 4 minutes at the following conditions. (During the monitor)
NOTE: When the system is normal, the monitor is completed earlier.
• Vehicle speed: More than 30 km/h (19 mph)
• Engine speed: More than 1,300 r/min, less than 3,000 r/min
• Engine load: More than 30 %, less than 60 %
• Without rapid accelerator pedal movement
3. Stop the vehicle in a safe place and turn the ignition switch to "LOCK" (OFF) position.
4. Start the engine and do Steps 1 to 3 again.
NOTE: When the vehicle is operating normally and the OBD-II Drive Cycle is carried out,
the Readiness Codes will be set as "Complete" on the first drive cycle. The second drive
cycle is required to set the Readiness Codes as "Complete" if a fault is detected during
the first drive cycle.
5. Confirm that the diagnostic trouble code (DTC) is not output.
