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.

• 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.
