Hey all,

I have a 2001 4runner limited. Not sure if this method works on other years but thought I would share. I had lights on my dashboard including brake, vsc, vsc off, trac and check engine lights. The speedometer or odometer wasn’t working either. The code I was getting was P0500. A local Toyota repair shop told me I needed a ECM or Engine Computer Module which new are $1,700 to $2,500 or used around $250 - $300 with no guarantee that it would solve my issue because the used one could be bad as well. So I ended up installing a used ECM and that didn’t work.. keep in mind when you install a different ECM you have to get your keys to work with that new computer which costs another $250-$500 because the key has a chip in it which is an immobilizer key. This is only on some models, you key will have a small dot at the bottom, if so then it has a chip in it.

So since that didn’t work I ended up replacing the ABS TRAC VSC COMPUTER CONTROL MODULE and sure as shit it worked. The second I cranked up my car all the lights went off and speedometer was working.

So, located under the driver side dash where the break peddle is - I would unplug and plug back in your ABS TRC VSC COMPUTER CONTROL MODULE to make sure its connected properly. If that doesn't work order one off ebay and replace it. For my 2001 the part number was 89540-35270. I would start with that first because uninstalling and installing takes 10 minutes if that vs going through the process of replacing the ECM, getting keys fixed etc.

Good luck!
