Lost All Keys? And Need a New ECM? (EEPROM video) 

I agree! I took the eeprom off of my amp clamp meter a few months back and changed a lot of the presets! It was fun learning this stuff

Thanks Wyatt!

Glad it was helpful!

Thanks for watching!

Thanks 👍

Glad you enjoyed it

Glad you like them!

Honestly, with a little practice this isnt hard at all.

If you have any good resources, i'd like to hear about them!

@@VoltageDropDiagnostics I'm just at the beginning stages, it's all new (again). Lots has happened since UV erasers and 2716s.

Thats who I am trying to emulate lol. At least his repair style.

@@VoltageDropDiagnostics Wow just commented about this on a VDD video and was poking around @SOD channel & saw this channel. Guess you already watch him @VDD 🤣😂 👍🤙

Awesome! Thank you! You're gonna love the tool!

Yeah, I have been practicing lately lol. Plus I got some good tips on my last video.

@@VoltageDropDiagnostics that's what makes a great technician.

Yes I wanna get the exact set up any tips or links please?

I love that tool! Especially the immobilizer side of it.

It's nice to see Diagnose Dan is watching this video,i always watch Dan videos

Great video. Would you be able to answer my question. I have 98 3rd gen 4runner with all original keys missing. Right now I have one dumb key for the door and one for the engine and the security system is off. Can I get a new programable keys and reprogram one or will that BRICK (immobilize) the car? I believe that 98 3rd gen was the start of the immobilizer. I just want a key that I can remotely open and close the door and activate the security. Thx

No problem 👍

Most definitely! Thanks Mario!

I’ve heard of this happening! That’s good advice.

Hi do you mean if i match the numbers on the eeprom? So i get the correct eeprom and just replace it?

@@onionrudnik6576 I have a. 2009 Mercedes C300 4matic I sent the ecu away for servicing they claim the ECU is burnt I had mechanic replace it with a used ECU from the same vehicle but a 2011 C300 now he claims he cannot program The key and Vin to match the vehicle. So the vehicle will not start Yes he has functions to all other properties of the vehicle. Do you think you can help swapping the original equipment to the donor.

I did it it did not work, I bought used ECM exact match number, I swiped the chip (Lexus LS 400 1998) It did not work. Somehow there is 2 programs the immobilizer immobilizer module and ECU and somewhere it's not working, it has to be done the way this guy did it on the video, has to be virgnised so the ECU goes into programing mode, that's my opinion. I'm still trying to fix this problem the car is still at the shop.

​@@xjssts7127that's interesting, I have a 99 Lexus IS200 and I thought about just swapping the EEPROM from the old ECU to a new used replacement.. did you get it to work somehow?

@@drossonero7595It took me almost one month but finally got it worked, it killed me but it worked. I swapped the cheap, you have to clean it very very good all the glueish residue, then you have to put soldering before putting the cheap put lots of past then solder the cheap, already the cheap is very small, it's a nightmarish job. Also the soldering the company use and your soldering is different, theirs melt much faster, yours is much harder and requares modified soldering tip so you can touch all the prongs at the same time so they can all melt at the same time.

Yeah! Finally!

Thanks! Will do!

Crap! I forgot to send you that message. Sending now lol

Glad you enjoy it!

Haha. These components are relatively easy to work with. I bet if you gave it a shot, you’d get good at it fast. I struggle with smaller components on cell phones and tablets.

Awesome, thank you!

Nice work!

Thank you 👍

Glad to hear it!

Thanks!

Thanks for sharing those tips! Since filming this, I’ve learned some of those lessons the hard way! Haha Do you have the tools for the VW modules?

@@VoltageDropDiagnostics You mean the bomb I need to get that thing to open? I just got a heat gun, and am waiting for a heavy duty scraper that is on its way. Do I need something else? Thx :)

@@renefuller9241 yes! head on over to Super Mario Diagnostics channel! He has special tools that he uses in a video, and show how to open them with the tools! And while you're there, tell him that I sent you!

@@VoltageDropDiagnostics Thx much!

Thanks

Without some type of eeprom tool, you wont be able to do this.

@@VoltageDropDiagnostics I still confuse, how did you registered the 2 keys after you write the eeprom ? Bcs I can see that you programmed the car without programmer tool

Thanks!

Thanks!

Thanks for the tip! Do you have good luck reading the eeprom in circuit with the autel xp400 pro?

@@VoltageDropDiagnostics I havnt used the Autel scanner for those purposes actually. Ive used the Autel Maxisys, Launch x431, VCDS, MB Star, and various other clone devices. But only as a scanner or to update/reset modules. To pull eeproms I use my Xgecu tl-866 or Miniprogrammer using the chip clip in circuit, or clamping or soldering the cip to a adapter board. Aside from the clips being finicky, I havnt had any issues reading in circuit with any devices. The primary issue being whether or not I can get a reliable physical connection using the clip. Could of course always run wires soldered directly from the chip legs. But thats a lot of work Id rather not do. lolz If Im pulling eeproms from VW/Audi BMW I use a Bench Flash cable I put together and a FTDI or CH431 cable and software created for the purpose like me_95040, me7eeprom, etc.

So for automotive circuit boards where the components are relatively large, I use a Yihua 862BD thats in my amazon store. For smaller electronics like phones, I use a hakko microsoldering iron.

If you want to just view it on a screen, I’m using an Eakins HDMI scope that can be plugged right into a monitor or tv If you want to film it, you’ll need a capture card to run it into a computer. I’m using an elgato camlink capture card to record it.

I assume you learned more then just unlocking Toyota’s? The info for unlocking these modules is all over the web! I would have loved to have sat in on that class!

@@VoltageDropDiagnostics read write all sorts eeproms beginners course but only have the toyota virgin file.

So, all of the chips have numbers on them. If you google the numbers it will tell you what that chip is. Some 8 leg chips are eeprom. Some are mosfets. Some are can transceivers. So it takes some leg work to figure out what all the chips do. But eventually you’ll become familiar with the numbers.

Yeah. The software comes with the IM608. If you’re in the states, i recommend getting from Isaac at NC auto rescue. He is a great friend, and provides support whenever needed with the tools that he sells! His number is: (919) 408-7320

@@VoltageDropDiagnostics Thanks PJ, I am in Canada will keep Isaac # I wonder price deference between Canada an USA will check it and thanks for all the info u been sharing really much appreciated cheeeeers.

@@jgeorges3061 call him, and let him know that I sent you. He just said that sales between US and Canada aren’t region locked.

Doesnt sound like youre making perfect contact or the wrong chip style was selected

@@VoltageDropDiagnostics can i mail you my ecu it's t eeprom 1 2000 Toyota sienna xle i lost all the keys can u please do it for me i will PayPal or whatever how much $ u want

The diagnostic side of the IM608 is just as strong as the autel elite 908. It’s probably the best all around scan tool on the market in my opinion. If you’re in the states, my buddy Isaac at NC auto rescue sells the IM608, and provides any necessary support with the tool. His number is : (919) 408-7320

Thanks PJ! Keep up the great work with the videos. I really enjoy them.

@@VoltageDropDiagnostics hie .great works .does this work apply to any toyotas with 4c

Googling the numbers on the chips and datasheets

I’ll be honest, i had trouble myself. So i just do the mathematical conversions in my head.

Yup! I agree

Its an Eakins HDMI scope.

Thats a tough question. I kinda learn from everywhere. A little youtube. Some books. Some google searches. There really isnt one place that I learned this from. It came from multiple places.

Thanks a lot for reply

That’s a good question. Here in the US, all newer Toyota’s can be reset with a scan tool. We only needed this method up to about 2004 model years. You might want to look into the autel im608. This has some cool features that might be able to save you from replacing the module on newer Toyota’s

@@VoltageDropDiagnostics Thanks! Will look into it. We can do 2 or 3 of these jobs a month so could be a worthwhile investment if works

@@MOTODANS i have another video using the autel im608 to go into a backdoor to program a key using a key emulator. Might be what you guys need

@@VoltageDropDiagnostics Will check it out!

Pre 2004 Toyotas are eeprom like shown here, Then mostly programmed through the obd2 port until H chips came out which require quite a different process and special equipment. The Toyota proximity fobs require an emulator. So no is the answer. Ask a locksmith or get instacode.

Thanks!

Tons and tons of research and googling lol

Yeah, I agree. I was asked to keep some of those tricks off of youtube. I just looked at your youtube channel and it looks like you have some cool stuff going on over there! I am gonna go watch some of your videos!

@@VoltageDropDiagnostics Thanks! I haven't really put up too much and my video production skills are severely lacking but yea we are in similar fields so might be something interesting for you. My background starts in automotive locksmithing.

Thanks!

Yup, you can

No, i didn’t remove the immobilizer system. I just unlocked it so that it could go into automatic registration mode

Yeah, i started doing this! It has definitely helped! Thanks!

Happen to open it up and look for any visual damage? Also, did you verify that none of the 5v sensors are pulling that circuit to ground?

@@VoltageDropDiagnostics I did look for any damage components but I couldn't find one. As far as the signal from other components, I checked directly from the Ecu and no volts, if thats what you're referring to.

Sorry, i don’t have obdstar.

On some modules, yes. Not on this particular one.
