How to write or program VIN to another ECU.

Hi, Dan here, from vehix411.com.
Today, I will show you a little video about Toyota.
This one is a Toyota Corolla O7. a common problem on Toyota and Lexus,
ECU would throw a transmission code, and it will not ship properly.
I’ve seen, actually, some with a EVAP issue, so the ECUs do go bad
on these, fail often, and when you do replace one of these,
you get one from a junkyard, the car will not start.
I have a video, actually, several videos, one of them, some of the older
ones, you can actually swap the EPROMS from one to another.
That will swap the number, and that will also swap the immobilizer information.
Some newer ones, like this one, it has a processor. You will not be able
to swap the E-prompts. Processors are super hard to swap, so don’t even try.
I have a video on how to program. What you do is just install a new or a
used ECU in the car, 30 minutes. You’ll have to short out OBD, and 30 minutes later, the ECU will be programmed to your car. Immobilizer will be programmed,
it will start the car. Now, the VIN number on this, you will still have to
write the VIN, because you will not pass the DEQ. So, since I already
programmed the computer, shorted it out, if you do need to know how to do that,
go to vehix411.com, and there’s a video, ECU Immobilizer Program.
Otherwise, once you’ve done that, get the VIN number. You will need a scan tool to program. This one is a snap-on, so pretty simple, nothing fancy.
And you will go to VIN Read-Write. And once you’re programming,
it will not program if the car is running, so when it says ignition on,
make sure it’s in the ignition on. I already did the programming
of this VIN number, but I will show you that you can just read off the VIN,
matches my VIN now, it’s good to go. Otherwise, when you do VIN Read and Write, it takes a while. And then you push VIN Write. And then, obviously, it
gives me a good current VIN. You just say yes, and then enter the VIN.
So, thanks for watching. Like my videos, subscribe, comment.
