Hi i bought the scan tool today cause was on sale for a 30$ . Anyway I just plugged it to make sure if works than after I read the codes (no codes and no pending codes as well) i put scan tool back to the box .
Than I start the engine and starts driving got vsc and vsc off lights on wtf!?
When I stop there is a only vsc lit on and abs flashing .
I'm so mad . Tried to reset battery but no luck .
How I could get rid off these lights now

Thanks for all input !

this happened to me, i have a can obdII reader and it trips the codes. i can't remember if i needed to do a zero point calibration or i took it to a mechanic and had him reset it with the proper reader

Thanks ! I'll wait for more suggestions

Yep, ZPC is what you have to perform in order to clear the fault code.

There are a few threads on how to do it with a paper clip, as well as a few youtube videos.. I myself just purchased a mini vci from over seas/eBay and it works perfectly.. Mini VCI Tis Techstream OBD2 OBDII for Toyota Diagnostic Scanner Tool Cable CD | eBay

As you can see they are fairly inexpensive and even if you check it once a month to see how your Toyota is running it will basically pay for itself the very first time you use it..

PS: You don't necessarily have to buy it from this person but search and it will pretty much be about the same price..



PS: Here's a quick thread for reference : Yep, Not another VSC TRAC/VSC OFF Thread.


PPS: Not sure what year T4R you have but here a video as well: https://www.youtube.com/watch?v=55XmiSsGQgo

A couple of years ago I bought a cheapo 25 dollar code reader from AutoZone. It tripped the VSC light also. I took it back to Autozone for a refund. I had to get a local mechanic with a 5K reader to reset the light. Then I bought a $99 reader from WalMart and it works just fine, including ABS codes. Moral of the story is you get what you pay for. The $99 was still pretty cheap, but good enough not to set any codes.

Thank you guys for a help ! I just did 0 point calibration using paper clip on my driveway . No more lights and traction works good !

My steering wheel was straight when I was doing calibration but the driveway isn't level so front of the car was higher than back . Idk is this will causing any bad seating for traction control module ?

You need to do the ZPC on level ground otherwise the vehicle learns "Level" or "Zero" at an angle and it could cause issues with how it interprets data on flat ground.

I'm guessing you have an '03 or an '04?

Yes sir ! 04 V8

I'll do this tomorrow again at some flat road

Ok alert!!

With my amazing mind I figured out how to clear Vsc lights with scanner

Ok so this is it instead of awaiting scan to be done..... once you notice the Vsc and abs lights start to blink a series of times turn engine off instead of allowing scan to complete test.

Trying to wait when it’s done and erasing codes won’t work you have to unplug and turn ignition off when Vsc and abs lights start blinking a series of blinks it doesn’t matter how many just as soon as you see them start blinking

Be sure to unplug the scanner from computer when you see Vsc and abs lights start blinking.... turn off ignition then with everything disconnected start up engine and test run your vehicle you shouldn’t have lights turn back on.

It’s so hard doing what some of those YouTube videos advise of and so I eventually did and noticed with my mechanical and technical mind of when it happens with computer and without computer this is the easiest and less complicated way to get it to work.

When you drive it to test it you’ll feel the difference in the drive that it’s fixed right away.

Hope that helps! ����

Success!!’

Look up "zero point calibration" on here, I had that issue after I mounted my scan gauge in my '03. Fixing it took five minutes to splice some wires together to do the zero point with, and like two minutes to actually do the calibration. If I remember correctly I just looked it up on youtube, super easy.

Can anyone link me to a cheap scan tool that won't cause the VSC light to trip?

I've never had a problems on my 05 with the Zurich ZR4 from harbor freight: ZR4 OBD2 Code Reader or using the torque pro app with the BAFX bluetooth reader: Amazon.com: Bafx Products - Wireless Bluetooth OBD2 / OBDII Diagnostic Car Scanner & Reader Tool for Android Devices - Read/Clear Your Check Engine Light & Much More: Automotive

I think this issue with clearing Zero Point data when clearing CEL is mostly an 03-04 problem from what I've read

I bought the one below back in 2016, looks like the price dropped. It works well with the Torque Lite app. Never had an issue with it on any of my cars. I have an original Scangauge that sets off the VSC light.

Amazon.com: Veepeak Mini WiFi OBD2 Scanner for iOS and Android, Car OBD II Check Engine Light Diagnostic Code Reader Scan Tool Supports Torque Pro, OBD Fusion, Car Scanner App: Automotive

Thanks for the recommendation! And yeah unfortunately I have the 2003 that has the VSC light issue.

Awesome! I’m gonna give this one a go.

Looks like Torque Lite isn’t available on iOS- anyone have an OBD scanner app for iPhone they recommend?
