Drive Cycle
1. Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 50°C (122°F) and within 6°C (11°F) of the outside air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic will not run.
2. Idle. The engine must be run for two and a half minutes with the air conditioner on + rear defroster “on”. The more electrical load you can apply the better, so turn on the headlights as well.
3. Accelerate. Turn “off” the air conditioner and all the other loads and apply half throttle until 55 m.p.h. or 88kph
4. Hold Steady Speed. Maintain a steady speed of 55mph for 3 minutes.
5. Decelerate. Let off the accelerator pedal. Do not shift, “touch” the brake or clutch. It is important to let the vehicle coast along gradually slowing down to under 20 mph or 32 kph.
6. Accelerate. Accelerate at 3/4 throttle until 55-60mph or 88-96 KPH This will perform the same diagnostics as in step three
7. Hold Steady Speed. Hold a steady speed of 55mph or 88 kph for five minutes.
8. Decelerate. This will perform the same diagnostics as in step 5. Again, don't touch the clutch or brakes or shift gears.
The video includes a guide how the actual inspection monitors are set for your GM vehicle.

2021 Chevy Traverse passed after watching this video! Drove 800 miles, gas and nothing smh. Was about to give up. did this to the Tee! Less than an hour Greatly appreciate you !

[Froztinc]

These drive cycles are insane we should be given access to a private track to complete all these procedures.

I did this drive cycle this morning after driving all day with three of my sensors not ready. After doing the drive cycle, the final two sensors turned ready and I can have my inspection the following day. I appreciate the walkthrough and explanation.

For me, the success of the drive cycle was the upon cold startup, turning on the defroster, AC…anything that can put as much electrical load on the system as possible. I didn’t do this prior and it made for a long day.

Also it is truly best to do the drive cycle early in the morning or late at night, preferably on the weekend as it’s when a lot of people sleep in. It made for a lot less concern and anxiety if you can only do this on a road that is often traveled at 65 mph minimum.

Thank you for this video! I only wish I would have found it before I wasted $80 on gas driving around aimlessly trying to ready the o2 sensor heater monitor. 🤬🤣
Have a awesome day and keep up the great work!

[catnhat]

Thank you! I just passed my smog (Class C motorhome on a 2000 Chevy Express chassis with the 7.4 liter V8). This video helped me get ALL my monitors ready (even the Evap System) in one trip, without a lot of gasoline expense and extra stress. Thanks again!

I finally got the drive cycle completed for my 2016 Chevy Tahoe. Great instructions. Just a couple things I had to do differently.

My O2 sensor would not set while I was trying to performing my drive cycle. I was about to give up and parked, let the car idle for a few minutes with the air and defrost on and turned off the vehicle. I waited a few minutes and started driving at 55mph for 3 minutes with no aie or defrost and it set.

Each time I allowed the car to coast below 20mph, I pressed the brakes before I started the next step in the drive cycle. (Before when I didn't hit the brakes below 20mph, it would not set)

I also purchased the ob2 reader you recommended and it's so much easier I don't have to manually hitting the buttons and keep checking the meter.

Gm, here in Ohio. Thank you very much for the information. I have a Chevy Malibu that failed emissions 3x and I followed the drive cycle as instructed. Once going to another emission location, I was able to pass the test. Again, thanks!

This video is outstanding. Had recent repairs to my chevy silverado 2500hd and was due for smog here in Cali. The smog place wanted me to drive 200+miles over the course of 15 drive cycles to get all the systems set. Found this video and got almost all sensors done in less than an hour. The only one sensor that hasn't set is the O2 sensor heater. Will try a cold start again once it's ready. Thank you for making this video!

[FearTheWhite]

You're a genius! Thanks so much for this video. I drove around for a few hours trying to get the o2 sensor heater monitor ready. This morning I started my '99 Suburban; turned on the A/C, rear defrost, headlights and the o2 sensor heater monitor was ready in just under 2 minutes!
Liked, subscribed and "Super Thanks"ed (from my other Google account)👍

[denisemarino]

5 STARS!!!! Thorough information, perfect!!!! Thank You...

[katprince]

This is by far the best video I've seen to run the drive cycle.Accurate and carefully explained on a state to state basis.5 STARS!

[nickhyslop]

In California they allow the evap not to be completed. But if you had a previous evap code you repaired and cleared all DTC’s it still stores in the I/M trouble codes as a permanent code until the evap monitor has completed and no DTC is set to verify repairs have been made. They will fail you even if there’s nothing wrong with the vehicle and you have no codes present.

[smashedfootlefty]

Awesome information! I've been trying to get my EVAP to set to smog the truck and this gave me the directions to get it set. Thank you!

[drome]

Catalyst hasnt set after following drive cycles. O2 sensors im readiness shows ready. Still think I should follow o2 sensors? 167 miles since codes reset.

[kaufmankdk]

Dear Sir,
This video has provided me with remarkable amount of knowledge of the smog process. Fantastic information.
I have a problem with the procedure for a 2017 Chevrolet SS Sedan. Battery was replaced and the dealer Cleared all codes and has been unable to get this car to pass smog.
Any specific data to support GM ODB2 driving cycle reset procedure 2017 Chevrolet ss Sedan.
Please advise.

VERY GOOD INFORMATION I PASSED MY SMOG THANKS

[lifewithoutfear]

When you told me that your now gonna show me how to do the drive cycle, I literally thought you were now gonna show me how to do the drive cycle!

[khbentaher]

Thank you for this helpful video, I have 2010 BMW 535 xi, and it suddenly shut down while driving, it gave check engine light, and message on the screen saying Fuel Pump problem. After that the car started and the check engine and the message disappeared. I need to read the stored or pending codes so I know which pump caused the problem. I would appreciate your advice on how to read these codes and what tool to use. Thank you for your feedback

[bluvsmore]

Thanks it worked for my 2019 chevy malibu. Failed emission twice after following your instructions it passed. My mechanic put me in the right direction to look into drive cycle.
Thank you. Ps issue was due to me disconnecting battery because. I had a p1101 fault, I did resolve the code issue first.

[Alaskabobb]

Had a catalyst monitor that wouldn't set (2007 Tahoe) but your video info worked in just 45 minutes. BUT, I then stopped and filled the gas tank, upon leaving the DIC started saying over and over that the stabilizer system was off, so, I then stopped and shut off the engine and the stabilizer thing went away but now have 4 monitors that are not set including the catalyst one. Maybe a ground? I am at a loss.
