The following is a description of the Hyundai Accent Drive Cycle. You must complete the Drive Cycle two consecutive times, allowing for a 30 second break in-between with the ignition turned off. Ensure your Hyundai Accent has at least 1/4 to 3/4 tank of gas. An empty or full gas tank will not allow the EVAP monitor to run. Also begin the drive cycle from a cold start; best achieved by leaving your vehicle sitting overnight. The drive cycle will not run if the check engine light is on or illuminated.
Usually driving 200-300 miles over the course of a few days and in both city and highway traffic conditions is enough to get the drive cycle complete. Due to individual vehicle owner driving patterns however, sometimes the criteria required to get a particular monitor to initiate and/or become ready is not met. In such instances, it is required that a specific drive cycle pattern which is designed for the Hyundai Accent, be followed.
How do I drive my Hyundai Accent to make the OBD-II monitors ready?
STEP 1: (Preparation)
• Make sure check engine light is not on and that there are no stored trouble codes in the computer. Use a scan tool to check for OBD II trouble codes. Any faults founds need to be repaired first.
• Start the engine.
• Warm up the engine (15 minutes at idle).
• Turn OFF the A/C.
STEP 2: (Steady State Driving - This is the MAIN part of the drive cycle)
• Drive your Hyundai Accent for 10 minutes at a steady state where the engine speed is between 2,000
and 2,400 RPM in 5th gear on a manual transmission equipped
Hyundai and “D” position on an automatic, using very little throttle.
Note: If during this step your Hyundai falls out of the required engine RPM do not worry. Simply attempt to get back into the stead state drive mode when possible. The 10 minute count timer will re-continue when proper RPMs are met.
STEP 3: (Switch from Steady State Driving to an Idle State)
• Bring the vehicle to a stop at a location where the vehicle may idle.
• Place the transmission in neutral or park
• Allow the vehicle to idle for one minute.
• After one minute of idling, press the throttle quickly to take the engine off of idle for a brief second.
• Allow the vehicle to idle for one more minute.
STEP 4: (Engine Stop)
• The drive cycle is completed.
• Turn off the engine (key in the OFF position) and wait 30 seconds.
• After 30 seconds, restart the engine and complete the drive cycle steps 1 through 6 one ore time. As mentioned earlier, the drive cycle must be completed twice.
STEP 5: (Final)
• After the conclusion of the second drive cycle, turn the key to the ON
position. Check to see if the Readiness Monitors indicate READY.
If all other emissions systems are functioning properly, completing the drive cycle above twice should set or make ready (complete) your Hyundai Accent's emission monitors. If the emission monitors are still not complete then check for any trouble codes and whether the check engine light is on or not. If faults are found make the appropriate repairs and conduct the drive cycle twice again.
Take extreme caution when performing drive cycles on public roadways.
