VXDIAG Toyota Techstream Program the Remote Starter Success

Another VXDIAG VCX NANO Toyota Techsteam review:

Vehicle model: 2010 Toyota 4Runner SR5

I just installed an OEM factory remote start on my 2010 SR5. Wife bought this for me for x-mas. The installation instructions are posted on various forums, so I won’t go into that (took about 2-3 hours). The biggest hurdle was programming the ECU to talk to the car… I did some research, got a knock off mini vci cable that included an older version of TIS techstream and had to hack the install to work on Win7. Super PITA. However, it can only do light modifications, like change the interval of the rear wiper, etc. It cannot reprogram ECUs, which is what you need to do. Took it to the dealer here (the only dealer that said they have the capability to install these). They couldn’t get it to program. They said they would have to uninstall everything and reinstall it to make sure it was done correctly, for about $500. No thanks. As crazy as it sounds, I knew they were messing it up somehow as I had followed the TIS instructions and it passed the initial diagnostics.

After more research, I discovered there is a Techstream lite and Techstream 2.0, which has the capability to program the ECU, these things were going for a couple grand on eBay. I FINALLY came across a Chinese site: www.vxdiagshop.com that sold ECU programmers. This was a little sketchy, but as I was up the creek without a paddle otherwise, I decided to pull the trigger. Was $60 bucks.

Unbelievably, in under 10 minutes, I had successfully programmed the remote starter. It came with a copy of the Techstream software and installed on my Windows 7 laptop without a problem. Here’s the link VXDiag VCX NANO for TOYOTA TIS Techstream V14.00.018 Compatible with SAE J2534

Hope this helps!
