I think this is absolutely fantastic, PJ. With these boards *so* expensive, board-level repair is going to be an increasing value and I think it's great to see!! Thanks for sharing!

[@VoltageDropDiagnostics]

Yes! I just hope to get the the level of knowledge that someone like Keith Perkins has programming chips and stuff like that!

[@sofianemessaoudi245]

​@@VoltageDropDiagnosticsI need some help how can contact you

[@codysautodiagnosticsprogra8706]

Awesome video brother! Really enjoy this type of stuff and it’s only setting you up for more skill sets for the future. Again great work

[@Longtrailside]

Very interested in learning more about this. I see it as a new wave of repair with the automotive industry going electric.

[@mikesabin8568]

Loved it. More circuit board repairs if you can are always appreciated

[@VoltageDropDiagnostics]

Thanks, will do!

[@High_Tech_Mountain]

Great job PJ. Thank you for bringing us along! Repairing circuit boards is definitely interesting!

[@VoltageDropDiagnostics]

Do you do circuit board repairs? If so, I'll take all the advise that you have lol

[@mikefoster3547]

Cool, it's always fun learning and honing new skills. Never be afraid of expanding your horizons. Excellent video.

[@VoltageDropDiagnostics]

I agree! Thanks Mike!

[@grabovg]

Awesome video again PJ, was fun to watch. It would definitely be an adventure to get started in this. look forward to more board repair!

[@VoltageDropDiagnostics]

The only downside is that I think we work for the wrong manufacturer lol We dont see many failed modules!

[@lowridermig]

Great job PJ 👏 👍 I really enjoyed the video.

[@VoltageDropDiagnostics]

Glad you enjoyed it

[@steveanderson4553]

PJ you did an AMAZING job 👍👍 I always wanted to try this. I think you just motivated me. 😉

[@VoltageDropDiagnostics]

Go for it! It isnt hard. Just need steady hands lol

Hello and thanks as always, PJ!!

[@VoltageDropDiagnostics]

Welcome!

[@diegorubio1073]

Awesome video , i might give this a try one of these days .

[@VoltageDropDiagnostics]

Its not bad, honestly! ECM components are fairly big compared to things like Ipads and phones

[@djosbun]

It looks like you've taken your valuable skills up a few notches, PJ! Thanks for showing us the details of your work!

[@VoltageDropDiagnostics]

haha! I am trying to learn! I still have a long way to go!

[@djosbun]

@@VoltageDropDiagnostics I'm a lot older than you, PJ (I'm 51) but I still push myself- and actually enjoy- learning new techniques that can make me better. You don't know how valuable people like yourself for taking the time to make these videos for us. A "thank you!" isn't enough!

[@two6s722]

8:00-8:10 you cracked me up , too! Great work, dude!!

[@gcmd5852]

Cool video PJ. It’s great not only diagnosing but then actually opening up the ecm and finding/repairing the issue. I stumbled across a channel I believe his name is Maic Salazar. He has a series on ecm repairs also.

[@VoltageDropDiagnostics]

Yes! Maic has amazing ECM repair videos!

[@shamessun]

Good job...... first step it’s have way to the finish line. Good video.

[@VoltageDropDiagnostics]

Thanks 👍

[@PaulysAuto]

Well that was pretty ninja PJ! Always cool to learn new skills!

[@VoltageDropDiagnostics]

Yeah, I have been messing around with circuit boards for a month or two trying to learn how to do this. I still suck though lol

[@PaulysAuto]

@@VoltageDropDiagnostics pfft sure fooled me man, pretty cool stuff PJ...I am impressed by how you always find new ways to grow and then you share it with others. I find it to be motivating and inspiring!

[@autogc22]

Very well explained. Thank you.

[@autogc22]

Let me ask you one question if you don't mind. If I understand well, you connected the positive from your power supply to both your test light and the bulb. The other wire of the bulb goes to the drain of the mosfet (or injector input of the board) and then ground the source of the mosfet back to your power supply. Am I correct?

[@VoltageDropDiagnostics]

Yup, that is correct. The this particular transistor turns on when power is applied to the gate. So I had to hook my test light up to power. Thanks for watching! And super observant as well!

[@centrotecnicoautomotriz302]

Buen video! Gracias por compartir !

[@tjautocare1607]

I really love your job. I am into automobile and I want to learn more about ECU repair in general it can be of great knowledge to me. I will appreciate your response

[@tharakanuwan9986]

Thanks for sharing. I would like to see you doing some EEPROM tutorials .

[@VoltageDropDiagnostics]

Oh man! I have been hoping that an old toyota came in that needed eeprom work.

[@arthurfricchione8119]

PJ I hope I got your name correct but I also have been trying to learn some of this stuff also on my own as a diyer. I was learning from Maic Salazar but his videos have stopped. I hope because he’s to busy. I’ve been following you for awhile I’m a retired aircraft mechanic but I enjoy working on cars and now I’m into it big time. I’m also into the tool aspect because I love my tools and now the electronic end of it. Thanks for sharing your videos and knowledge and stay safe and well Artie. 😊 very nice surface mount solder joint 👍 Pj is the power supply and hot air gun in your Amazon store. Guess I could look but then I might d buy to much LOL

[@VoltageDropDiagnostics]

Yeah, the power supply and hot air station is in my store. They’re knock off brands, but they seem to work fairly well for me. I love Magic’s videos! I have been watching northridge fix lately. He fixes small electronics. But the concepts carry over.

[@TrainedbyTechs]

Oh ya...awesome video!

[@VoltageDropDiagnostics]

Oh yeah!

[@akramsha8504]

very nice brother

[@VoltageDropDiagnostics]

Thanks for watching!

[@v4vauxhall498]

I've been micro soldering for years mate, your skills are right up there, if you anticipate doing a lot more of this stuff , i would suggest you get yourself a good quality extractor, would also suggest hand protection ie gloves or barrier cream, lead once absorbed into your body can not be secreted through any body functions, its there to stay, Regards Joe

[@VoltageDropDiagnostics]

Thanks! Do you have any recommendations for an extractor? I know that I need one, for sure! The smell of flux is nasty lol

[@v4vauxhall498]

@@VoltageDropDiagnostics I got a secondhand pace unit from ebay , they are quite expensive , but a must if you are doing a lot of soldering. Regards Joe

[@LiamandDadlaadventures]

Again great video and knowledge!! Just one question was the engine harness damaged in anyway/replaced?

[@VoltageDropDiagnostics]

Yeah, the rodent chewed the injector wires. The wires were just repaired. But after the repair, the ecm still wasn't commanding the control wire to ground.

[@nservice1625]

Great video! I took your WP class last weekend. I really enjoyed it. I am curious where did you found a quality replacement driver for this PCM?

[@VoltageDropDiagnostics]

Nice! I’m glad that you liked it! Most components i find on mousers website

[@billrimmer5596]

That was super!! Where did u get the driver? It would b nice to if u made a list of all your tools and supplies that u used. As soon as I c VDD vid, it's time to drop everything and learn something really helpful. Thank u!!!!

[@VoltageDropDiagnostics]

Thanks for watching Bill! I do have the soldering station and power supply in the amazon store like you already seen lol

[@Xencer]

Awesome! I had an 2007/2008 model Tundra, customer came in with 1 shift solenoid code, code would not clear and would set with key on. Confirmed continuity from ecm to internal trans wire was good, bench tested solenoid as good. I condemned the ECM and the customer declined, I wonder if it could be fixed in the same way.

[@VoltageDropDiagnostics]

Would have been cool to open up and see!

[@davelengerjr.4123]

Hey PJ, Awesome job. Where did you get your PCM parts at? I was wondering if I might be able to purchase such parts. Do you have a go to place that you recommend. Would you mind sharing some links of the tools used and parts used?

[@VoltageDropDiagnostics]

Mouser has been my source for parts so far. As far as the tools used, the soldering iron is in my amazon store: www.amazon.com/shop/voltagedropdiagnostics?listId=25U51J3KK15QV

[@jflee1]

I thought this was amazing! Thank you. I have one question about this though. Would you know if that just effected one single injector or does that control multiple injectors?

[@VoltageDropDiagnostics]

Each injector has a separate driver. So this would just effect one injector

[@tommego1]

Nice job 👍🏻, can you tell me please what was your heating temperature set in the heat gun. Thanks for answering

[@VoltageDropDiagnostics]

My heat gun was set to 650. For full transparency I have no idea if that is the proper temperature or not. But thats the lowest setting that I could use that would actually remove the transistor in a reasonable amount of time lol

[@shanelloyd8366]

As Dan mentioned in an Earlier comment id like to know where you would recommend replacement drivers from and how do you identify which is the correct one?Compatible replacement. TIA. Ps another great Video and extremely interesting and useful stuff I can apply to my work. 10/10

[@VoltageDropDiagnostics]

Hey Shane, Im still new at this so it takes me a lot of google searching and cross referencing. But I usually find the components on mousers website after finding a "like component"

[@autodiagnerdzllc8966]

Hi! Where did you purchase the driver Eprom from? Thank you. Good video. Thank you for sharing.

[@VoltageDropDiagnostics]

If you don't have any circuit boards laying around with good components that you can steal one from, id check mousers website.

[@wesleysalter484]

Well done 👍,where did you get the new driver chip from and what the correct name for it?

[@VoltageDropDiagnostics]

I usually google the part number on top of the chip and try to cross reference to mousers website

[@bulletbobweldon1442]

Awesome job! Where did you get your training info from? What kind of soldering iron are you using and what heat gun. I have always wanted to do something like this. Thanks for sharing

[@VoltageDropDiagnostics]

The soldering iron and heat gun are in my amazon store. It is a cheap knock off unit but seems to work well for automotive circuit boards. I did need to buy a micro soldering iron for electronics like phones. The soldering iron is in my amazon store: www.amazon.com/shop/voltagedropdiagnostics?listId=25U51J3KK15QV

[@VoltageDropDiagnostics]

Also, as far as training lol I watch a channel called north ridge fix. He fixing cell phones, iPads, etc but all of the concepts carry over

@@VoltageDropDiagnostics i m watching him fixing circuits too. This is something which i always wanted to learn.

[@billrimmer5596]

Another source for the part would b the dozen old computers u have underneath your tool box. As fast as u took that off u go into competition with Mouser and undercut him

[@VoltageDropDiagnostics]

Yes! I started taking components off everything that is broken and keeping them lol

[@tetttettamilli6761]

Having a scope, and most importantly, knowing how to use a scope is critical. That said, as a cost effective method - what about using a $35 O2/exhaust gas detector? If those cylinder heads are cracked, wouldn't there also be warpage, too (I take it the engine overhead?)? Lastly, is this the 1MZ?

[@VoltageDropDiagnostics]

Hey Tett. I’m wondering what you’re referring to lol. This comment appeared on a circuit board repair video so I’m a little confused haha. But I’d like to answer your questions. I’m just not sure which video you’re referring to lol

[@tetttettamilli6761]

Yikes... My bad. I caught it (that I posted comment to the wrong video) only after I commented. In the correct video, you used a scope (on two different channels) and a pressure transducer to see possible power pulses in the coolant. I think it was an older Toyota pick-up (or Forerunner?). At the end of the video, you removed the heads which showed a crack between the intake and exhaust valves. I tried to find the video, but couldn't.

[@tetttettamilli6761]

All right.... *extremely red-faced with embarrassment * It wasn't this channel; sorry 'but that. BTW, great channel - loads of info, with a good learning environment, too. I'm happy to have subscribed. Again, sorry about that mix-up.

[@DanWallis86]

This might be a dumb question but where do you get replacement drivers from and how do you identify which is the correct one?

I usually start by doing a google search of the numbers painted on the driver. Then try to cross reference them to transistors on mousers website
