Im not a auto tech. I work around heavy industrial applications. I use a old fluke 123/003. For me its a great tool because I can see more and replace very expensive parts with almost 100% accuracy and confidence. Owning a scope forced me to learn and understand most everything at a much higher level. I plan to buy a Pico and learn even more. No, I wont make a red cent using it, but thats ok. I love to learn and it make me feel just plain good. When co worker give me a hard time about all the money I spend on tools I tell them its better then a crack habit. This is what floats my boat and back off. They back off really fast when they realize they dont know jack and I might be a good guy to know if they ever need technical advise. Yes a good tech should own or plan to own a scope and get good with it. Electronics are only gonna get faster and more complex.

As a home bolt breaker. I watched a video of tech chasing a CAN signal problem. He hooked his scope into the OBD2 test port.
You could see the problem on the scope. Instead of being mirror image of each other. You could see the interference in the signal.
He found a CAN junction connector. And just unplugged connections until he saw the signal go normal.
WALA it was some controller in the over head console.
Boom that made me want one. I found out you can get a Hantek 1008C on Amazon for about a hundred bucks.
Thats shade tree tool money right there. Came in the mail today.
Have zero idea how to use it. But cant wait to start to learn on it.

When hiring a tech at my shop, the first thing I ask is what type or brand of lab scope they are using. 9 out of 10 times they look at me like I have 3 eyes. I ask this question because if they haven't used one then they aren't a true diagnostic tech. It is 100% impossible to perform a 100% perfect diagnosis, along with repair verification, without a scope when dealing with any kind of engine/transmission management sensor. With a lab scope, I can go home at night knowing that the issue is definitely repaired and has zero chance of a comeback due to my diagnosis. Rather than thinking to myself, Oh, I hope that car doesn't come back with the same code.

Your videos have helped me tremendously. My retirement budget didn't allow me to go with Pico, but I'm very happy with the Hantek 1008c scope, cc-65 and cc-650 clamps. I know they are not as refined as the Pico, but they have helped me diagnose a lazy fuel injector and verify a bad crank sensor. I also sprung for an Autel MD808Pro and GTC 505 ignition analyzer along with assorted backprobes, leads, etc.
But regardless of the diy equipment level, your sharing of knowledge has led me to learning about diagnosis rather than loading up the parts cannon. Thanks!

I know I've seen this before, but its well worth seeing again. Shortly, after I get most of my projects done, I'll be back with the Pico on my test subject, AKA the 06 Nissan Frontier, 4. 0 V6. Hopefully I'll learn how to print out the waveforms for reference later on. AND I hope last summer's timing chains, guides, tensioners, water pump, tons of O'Rings will still be good allowing me to see the timing marks alignment. Nice Job Mr. O. Totally Professional, and as an Instructor, Totally Understandable!

This issue I find. is where to find those known good waves. and most shops I have worked at do not supply Im Not Testing Nothing. I didnt even know that IATN still was around beings Idenifix is the prominent site for most. But I have always liked the personal aspects of Iatn. Where is you and I. and a whole ton of all the informations that isnt for those that are in the Every maked and models, everyday and unforgiving. I miss my brothers.

Erick, GM has had problems with improper tempering of timing chains, esp with Cadillac, I have seen chain stretch on part of the chains where half of the chain looks good and the other half stretched, and as early as 8K on the odometer! Caddy tried to band-aid this with PCM reflashes making more frequent oil changing intervals. You can blame GM for subletting the chains to Asia for sub standard manufacturing.

It's a shame I love auto electric one of my favorite parts finding out the mystery but I feel if I knew my head from my ass about a scope I would use it for more then just electrical problem is getting my hands on one keep up the videos your a very real guy and when things turn in to nightmares like the Honda strut video I know I'm not the only one that has terrible days

Yes scopes are DEFINITELY a requirement, if you want to diagnose and not use the parts cannon! I'm just learning my Pico, so for me it's a slow process. Eric, when you make a change with the waveform or waveforms, please point out what button and/or buttons your clicking on, which helps to understand what's going on when you do this procedure.
