Everyone Should ALWAYS Do This Before Buying A Used Vehicle!

This is an excellent tip. Many scan tools have a separate I/M readiness function, which might be quicker and easier to access than going through the OEM diagnostic menu. For scan tools without a separate I/M readiness button, reading Mode 6 data on the OBD-II side of a scan tool may also be faster than going through the OEM side of a scan tool.

[@SeilerRdAuto]

Best advice for folks looking at used vehicles. This does not mean that there won’t be any issues whatsoever, but this will tell you a lot about the vehicle and the folks selling it. 👍

[@chrisb9478]

Good video. I also learned on KZbin when I buy used to go on your test drive, make turns left & right all the way to lock, listen for cv noises. When you get back, look under warmed up car for any leaks. Have someone rev engine while you look at exhaust to see if any smoke (burning oil). This worked well for me on 2 used Subarus that we ran with zero problems. One with 133k & 99k miles, neither use any oil & everything works. 👍🏻

[@richardguo1892]

Yup, this is a good trick, I know someone who bought a 18 buick encore that had a cracked turbo housing which sets low boost code and trigger CEL to come on. The crack is not too bad so usually takes many drive cycles to set the code, either the seller or the previous owner cleared the code and the vehicle was sold to her with this problem. Luckily GM had a special coverage on this year and model so she got the turbo replaced for free.

[@Bizija123]

I've seen an obd data parameter in my car that says "miles driven since code clear." That's another good one to look at. Of course that could mean that something was recently fixed and codes were cleared as well. It will not always be something they're trying to hide.

[@mickmella]

Wow, glad i subscribed a couple days back! I'll be browsing to purchase for a couple years old vehicle and THIS method is; the guiding light! MERRY CHRISTMAS; THANK YOU!

[@drchico-nf6qy]

I have watched lots of channels but non is like you You are truly academic tech.

[@JimmyMakingitwork]

I'm so glad I'm not the only one preaching this to customers and viewers. We see WAY too many vehicles brought in for inspection AFTER being bought. Never do that folks, unless you're buying something really cheap that just runs and drives knowing it will only last a short time. Any serious vehicle investment should be checked by your mechanic. Two biggest issues, frame damage poorly or never repaired, or worse covered up and trouble codes recently cleared hiding major issues.

[@omarvasquez6851]

That example that you posted really happened to me and I took it back to the used car lot and they actually fixed the issue. That happened long ago and I still appreciate it. The car lot doesn’t exist anymore.

[@clonexradio]

readiness monitors, yup, this is my go-to trick to seeing if codes have been recently cleared!

Nice GS, I bought a new F-Sport back in 18, it's such a good car. Oil changes every 4months or 4,000 miles.

[@shootsnscores-cja]

[@aavz5330]

thank you for sharing this information with potential used car buyers. I didn't know this code reader existed until now. When I get into the car market again, I will definitely consider purchasing one to help me identify the best car for my dollars.

[@BCole-bj4lv]

Nice info. I know my dongle thing has a spot at the end of the "streaming data" that says, " how many starts since the last reset" and something else related, miles driven, perhaps.

[@MsFireboy2]

Happy Holidays. Thanks for posting. Being a former tech I always highly recommend a complete vehicle inspection and Complete Code Scan.

[@snaswedey]

In Sweden you have 3-6 months guarantee if you buy from a car company. So you dont really need to check for hidden faults. Also a mandatory car inspection once every year. If they find something that had been there for atleast a year, well then you can claim your warranty =) If you buy private, well then its up to you to check things, bit also here you are covered with swedish law

[@PaperCoffeeTable]

Yes, but if you call the dealer about an issue they’ll try everything to ignore you, convince you, or try to get away with it. Speaking from experience.

[@User-y9t7u]

It is better to look in generic OBD because the monitor information may not be in the data stream. You can also see permanent codes on newer vehicles. Also verify the bulb check is good.

[@onenikkione]

You have a video on that?

I paid a mobile mechanic to go to a dealership to inspect a car for me. He basically gave it a 8 out of 10 and I still have it two years later, pretty much it's been trouble free. It had 119k miles used

[@NorthEastRepair]

You also forgot to mention thr odometer in the live data to know weather the mileage has been tampered. Very important. Fyi

[@theroyaltyautoservice]

We will do a more detailed video in the future. This one was more designed specifically for the one thing. You’re absolutely correct that people should look at that. Thanks for watching!

Welcome sir im a fan always watch your videos and really learning alot from your content keep it up. Thank you

I’ve got a 05 ES330 that I can’t for the life of me get the CEL to stay off keeps throwing small Evap leak code. I’ve looked at every Evap hose and can’t find a smoking gun. Anyway hope you guys can do a video on this one day.

[@on-site4094]

That’s a good to find out if it’ll pass emissions what about the rest of the vehicle

[@marclours]

Why ? why, oh why this video was not made 3 years ago ? Got a CRV with Cat code exactly 1 week after buying it; good news: it is not clog and no emission test is needed here. Thank you very much for this useful tip.

@@deerhunter8533 I guess I'm the only one to blame for my actions :)

[@davepage2466]

In CA they put a probe in your tailpipe. Par for the course in CA.

[@timmueller1314]

It's been my understanding after doing my own maintenance on my 96 Chevy Lumina van using the GM factory shop manual that the check engine only comes on if there's a problem with the emission system. It won't come on for other general engine problems like a fuel pump going bad or a bad sparkplug, e.t.c. But my vehicle is 28 years old so that might not apply anymore.

[@deerhunter8533]

Bad spark plugs will cause a misfire. You will get a p0300 random cylinder misfire or a specific cylinder misfire code. Both of this situations are considered emissions related since they will affect the emissions of the vehicle

[@JohnStray569]

I can’t count how many customers bring their cars in for inspection AFTER they have already bought it.

[@alb12345672]

NY won't give an inspection sticker if the monitors are not set. There is also safety. Dealers MUST affix a sticker but a private part you have 10 days to get one so buyer beware.

[@buckman840]

I'm not doing a ton of wrenching on my vehicles beyond the basic oil, filters, spark plus, lights, etc. Does the DIY dongle give enough details on the code or does this require a pro version?

[@wingfoottech]

The other excuse for incomplete monitors is a recently replaced battery

[@LarryWebb-g5d]

Could you cut the catalytic converter off and weld in a pipe , then program out the emission sensors ? I removed my old seats that had airbags from my 2022 Chevrolet Express van and installed new seats that don't have air bags , now my airbag light is on my instrument cluster , I don't know what to do

[@AndrewMiller-vb9sx]

As a tech myself I got burnt lol bought a really nice 02 highlander 4x4 low mileage didn’t highway test it didn’t scan it before buying got caught up in how nice it is discovered days later wouldn’t go into overdrive wasn’t showing any check engine light put the scanner on it had knock sensor code! and 02 sensor code! the rotten bugger chiseled out the bulb for the check engine light the secondary 02 sensor plug runs under the driver seat was unplugged!! Why? lol ended up plugging back in and did the knock sensors everything was fine but the stupidly somebody went through instead of just repairing was baffling ended up being an awesome vehicle 2 my kids got their licenses beat up on it been my best vehicle to date still using it daily

[@jameelkhan3161]

Could the DIY dongle work for this specific or does it have to be the pro dongle..

[@jameelkhan3161]

Asking since the price of the pro dongle is double that of the diy one

What's your advice on buying a non-running vehicle that is appropriately priced?

Hey how’s the gearwrench pro dongle. Would you recommend for the diy person

Merry Christmas everyone! Be sure to get your car battery checked before it gets too cold out there.

[@starastronomer]

If the battery got disconnected for replacement wouldn't that cause some of the monitors to not be "ready"? Using a battery memory saver will eliminate that.

[@theroyaltyautoservice]

Yes you’re correct. Just be aware they may say that’s what they did and that usually will be the truth but it could be a lie and it’s a risk. Would be best to have them ran before buying.

[@swav100]

Or you can just check mode 10 if the car is 2010 and up

[@Karrpilot]

I tell people to buy what they can afford to pay off in 3 years, and to only buy new. Nothing worse than having a breakdown, out of warranty, and paying for an expensive repair, as well as the note on the loan. If that means buying a no options Toyota, as opposed to a loaded up premium car, so be it. One needs a ride to work. It doesn't have to be in a Mercedes to make it.

[@richardbeckmann6720]

Or. You could tell them that you intend on stopping at a auto parts store for them to scan it before you buy it or no deal

[@RamBo-uu9so]

Don't be fooled.....they still rollback the odometer. Ever heard of anybody getting busted for that? No. Never.

And Carfax is total BS. If someone had body work done to their car and payed out of pocket to fix you'll never know because Carfax works with insurance company reports/police reports. So don't just assume it's all original paint/body.

[@kirkdarling4120]

Carfax isn't total BS, it's just not complete. But it does tell you what was done. When I bought a used car last time, it told me that the oil changes had been frequent and regular. It told me major services that had been completed. That's good information to know, not BS. It just didn't tell me what it didn't tell me.

[@deerhunter8533]

Unfortunately most people will not be equipped or have the knowledge to do this test. It is a bullet proof method of finding if someone cleared the codes to hide problems. My subjections if to have the car looked up by a competent mechanic before purchasing
