Tacoma No Start No Communication with ECM-Circuit Board Repair

[@SuperMarioDiagnostics]

I liked the video. Now, I'll watch it.

[@robertmedina6875]

That's how I do it so I don't forget to like the video

[@VoltageDropDiagnostics]

My man! haha

[@djosbun]

That's standard operating procedure, right? Click 'like', watch a few minutes, type a comment and then finish watching the rest of the video. That's what I always do!

[@SuperMarioDiagnostics]

@@djosbun haha, not always But i haven't been let down by pj 😄

[@petar443]

You and Mario . Thanks guys for these great videos 🍻

[@VoltageDropDiagnostics]

Oh, mario is head and shoulders above me right now! He is killing it!

[@nutsnproud6932]

I am glad you used conformal coating after the repair.

[@johntrauger68]

Might I add... Rosin, not acid based flux for electrical equipment. The Navy pounded that into our heads during my aviation electrician training over 50 years ago. Cheers!

[@LetsDriftMedia]

Awesome video thanks for showing how its done!

[@VoltageDropDiagnostics]

Thanks!

Cool finish with pulling the 5 volt ect to ground.

Thanks!

Thanks for watching!

Solderwick, bro. Those solder suckers... suck. As a current techie and former mechanic, I'm impressed with your knowledge of these ECM's and your test rig. Next step, swap out old ECM with a Pie-4 😆, I've seriously given this some thought but the programming, oy, not my forté.

[@juergenscholl2843]

Thank you for this video. You may want to try using copper tape in order to repair/replace broken traces on the bord.

[@VoltageDropDiagnostics]

I’ve seen people doing that. I haven’t tried that method myself. Have you had good success using that method?

[@juergenscholl2843]

@@VoltageDropDiagnostics Yes, it works well for me. Especially when the trace you want to replace isn't a straight line it makes life easier.

[@VoltageDropDiagnostics]

@@juergenscholl2843 do you cut the trace out of a sheet? That’s the only way I’ve seen it done

[@juergenscholl2843]

@@VoltageDropDiagnostics The copper tapes comes in various widths, from ¼ to 2 inches. The wider one allow cutting out the traces as needed. If you got some cumbersome forms you can just add on the required number of pieces and join them together with a solder dot once you glued them onto the board.

[@neverstoplearning382]

This is great stuff. Thanks again.

[@VoltageDropDiagnostics]

Thank you!

[@carstengotfredsen160]

Inspirational video, as always. Keep up the good work :)

[@VoltageDropDiagnostics]

Thanks!

[@mooresautorepair8370]

Looking to add this to my auto shop. Did you take any training. How did you get started. I am very interested

[@VoltageDropDiagnostics]

Honestly, i started watching electronics repair videos for things like cell phones, laptops and tablets. Then I started saving failed modules to practice on.

[@hoaxs1939]

Great Video! Keep it up

[@VoltageDropDiagnostics]

Thanks!

[@florenciomartinez3695]

My shop also does this type of work, i have a question if you don't mind me asking, in cases like this i'm sure you ask or tell the customer their options, a new pcm or repair, so my question is with inflation and such are more customers opting to get them repaired instead of a new pcm I know some boards are not repairable but the ones that are i too give them the option some choose to get a used or new , does your shop offer the option of used boards? My props to you excellent work!!!

[@carp2966]

This ECM wasn’t available as a new part. It had been discontinued. Repair or source used was the only option.

[@danman9017]

nice work

[@VoltageDropDiagnostics]

Thanks!

To open up a thru hole, heat the solder, then push a wooden toothpick thru the hole. I urge getting a desolder station or a least a vacuum pump on the solder pulllit. Solder wick is also good. I use denatured alcohol for cleaning. It dries quicker. The solder looked like it was not bonding easily. Is that lead free? I use a single strand out of a stranded wire to make patches. I also use a very fine insulated hook up wire for longer runs. Can I send some to you?

[@VoltageDropDiagnostics]

Yeah, it’s lead free solder. But i struggle with solder wick in through holes. Have a suggestion on a high quality wick? And i really want a Desolder station. Maybe one day.

[@ranchorelaxo2287]

@@VoltageDropDiagnostics the Hakko desolder gun has been a very good tool for me. It was worth the money and has good "heft" to it vs another unit that shall remain nameless....

[@stevepark5504]

@@VoltageDropDiagnostics I use tin/lead solder, it wets better. Never tried no lead, what was on the boards was difficult enough. Wick is pretty much wick, It’s just fine copper wire braid with flux. The flux is the difference so I add flux. I didn’t mean to use wick for holes, its more for mopping up. Either a pick to push it out or a vacuum desolder is best for thru holes. A desolder station will pull the solder out of things like those caps with the cap in place. Much easier than wiggling them out. Or the cap can be pull/twisted off the board then each lead desoldered. The size of the components on these boards doesn’t require a microscope camera. A magnified headpiece allows full access for tools. Desolder irons vary in length of path to capture the solder. The longer the path the more likely it is to plug up and they all do. More from idling than using. I think you’ll find after you get the desolder tool that it should have been the first tool acquired for thru hole work. The extra time and risk to the board makes it worth it’s keep.

[@thesmartguy3523]

Awesome video(s) mate 😁👍 new to your channel, so binging on some of these videos, I was curious about that blue plastic (or rubber perhaps?) board, which keeps things organised, the ECU, screws, other small components and what have you, could you tell me the name of the board or a link to where I can purchase one from ? Thanks in advance

[@Rojaktube]

I see that you connect the SDL line to the K-Line connector on the GODiag. Is that correct or do you connect that to pin 2 of the OBD2 connector? Or do I need to connect both? How about the ground. Must all the ground be connected on the ECU? If no sensor is connected, will there be communication with ECU? Thanks.

[@louismouton8094]

Don't keep breathing soldering smoke! Get a fume extractor and make your lungs happy ;) Nice repair anyway!

[@VoltageDropDiagnostics]

Yeah, I have a cheap filter. But it doesnt seem to work well! Im going to upgrade it here soon!

[@josel.martinez6700]

Hi, do you still work on these? I have also a 96 Tacoma 2.4l that needs recap and possible trace repair.

[@davelengerjr.4123]

i was just curious are you not working at the dealership anymore

[@jeremyanthony9300]

Are you still working as a toyota tech?

It was bad before I fixed it.
