I notice some testers operate at about 30psi and this one at about 100psi. Does this make any difference?

Man, you make it seem so much easier than I was thinking lol made more sense with you explaining things!

love this, Thanks

Lightning strike my head - battery ground & #4 DLC voltage drop, never thought about that. That is the real bomber shaking my brain.

Will I be able to use any scope to do this test ?

Do you have a A1 Video? Your videos are helpful

Thank you so much for the video. Great effort we learn from the best (master)

Awesome video. I'm 71, in our days all of us gear heads used this gage. Great job

Great info. Subscribed.

Excellent advice I’m in a emission inspection state very interesting about the temperature rate

thanks dude , very informative

Thank you very clear instructions and expert tips you can only learn from someone whom is a true master mechanic Thanks again!

Great video. Working to diagnose a misfire my CT200h. Just waiting on my tester. Being a Prius engine it's probably the head gasket 😮‍💨.

Saludos Master, muy buenos detalles para que el conductor nos facilite aprender que sucede con su carro. Mil gracias por el formato de entrevista. Didio desde Panama.

Very informative video. I rebuilt my toyota engine, and it fired up on the first attempt. However, I noticed within a minute that exhaust pipe overheating and compression loss. I was confused and thinking where to diagnose. now your presentation explains well. Please let me know if i need to test something else. Tku

👍👍

Very good info!

With your videos I I’ve been able to Pass A6,A7, and X1 all with in a week apart of each other thank you so much for your help!

Love your content Oscar! Keep it coming!

This guy is how I’ve passed multiple ase tests - recently A8 engine performance! Amazing videos man!

Master mil gracias por tan buenos consejos que nos ofrecen en los variados videos. ✅✅✅ Didio desde Panamá 🇵🇦

Great video I have the d7s, still learning tips on using so thanks for video. I do have a question though. How would I know which obd2 option to pick for my vehicle ? The newest I have is a 2004. Thank you for the great content!

SORRY BRO BUT XTOOL iS A PIECE OF CRAP I WILL NEED A NEW PCM FOR MY CAR JUST BECAUSE XTOOL SOFWARE IS GARBAGE GOOD LUCK FOR THOSE WHO GET XTOOL

Thank you amigo for sharing your knowledge G Bless

Gracias Master potty informacion. Saludos. Didio de Panamá 👍✅🇵🇦

Really good usable information: thank you!

I really liked this video. I would like more videos on reading and understanding the PID values given on scanners.

How about a hybrid with so many history codes your scan tool can’t read them? I have a GWM HAVAL H6 HEV with over 200 codes all history. VEHICLE DRIVES 26km then feels like a misfire or disconnect and looses all power. No indicators no hazards no HUT no fault light on the dash or EML on, but, there’s a rake of history codes all relating to communication. Too many to actually find a starting point! I’m fried!

Great video

Thank you for sharing your expertise with the world! 👏

Great information…I’m studying that now ..I have been having difficulties to understand what are the most important pids to see before anything ..now I know and betters than that ,Why ! Thanks appreciate

What is your opinion on the smart phone OBD2 Apps like Torque? Are they useful and can those apps point users in the right direction when trouble shooting a vehicle? Maybe you can do a video on it.

Great video! Love it! ✅💪💯

Like always , great info tha ks for sharing Can wait for next class on the bay area

THAT WAS FANTASTIC ,,,,,,,,,,, HOW ABOUT A CLASS ON NO START DIAGNOSTIC PLEASE KEEP UP THE GREAT WORK !!!!!!!!!

Next steo

Buenas Tengo un ALLOSUN

Brother! I watched your A4 video and it was great. Totally helped me pass. The first 30 minutes of this video is you talking about yourself. Wtf?

I must have been given a different L1 test there was no mention of Grandma's car.

The story of the brake light is indicative of something that could be remedied if the government actually made it a law that every manufacturer had to give the auto industry the flow of operation in design of systems, as well as all of the variables engineered into each system, so we as techs could diagnose systems without being blind and playing a frustrating game of what might be how it is supposed to work versus how it works verbatim from factory. Instead, all the government and industry gave us was the universal OBD 2 connector. I, personally could repair anything more efficiently, if I just knew, for example, what each electrical circuit is required to do while it flows in and out of modules, computers and other electronics. Having a partial wiring diagram and not knowing if this circuit is flowing through this transistor once it reaches this voltage and then a driver shuts this circuit off at this resistance and when this other adjacent circuit receives this amount of current this happens, etc, etc... We need proper information. What we have to do every day is guess how a system, electronics and computer programming are designed to function. Mitchell, Identifix and Alldata do not have complete information and it is very irritating. A.I. on the net is not accurate as it chooses the wrong information and presents it as a fact lots of times. Nobody can afford manufacturer backed factory direct scan tools and their database for each make and model. I have been in the field for almost 40 years and the lack of proper service information, that is, complete information is terrible. Straight from factory vehicles are bad enough, but it gets really tough when working on things like Pierce ladders and engines... Wheeled Coach ambulances are terrible also. This industry stopped being easy when manufacturers across the board in every field decided making money was priority one and withholding repair information as well as equipment and software and rebuildable/repairable parts obsolete. I will continue to keep trying, but it is like you are constantly treading water and keep bobbing under. Oh well... that is my rant and it felt good!😂
