Hi, im new here and I could not find anyway to do a zero point calibration on my 09 lexus ls460. Now to get you caught up, I recently went to get an alignment because i had new tires and after leaving the alignment place the traction control light went on and I read online that it can come up after an alignment which I did. Now i also heard you need a tool to reset it but i dont have one and was wondering if there is anyway to reset it. I saw some people using a paper clip on their obd on youtube but its not clear to me and i dont want to mess anything up.

 

Welcome Moe,
from what I've heard, the zero point calibration is achieved by disconnecting the negative battery terminal and while disconnected. To perform the wheel alignment. Once everything is aligned within spec, then the negative terminal is reconnected. Then the computer automatically recalibrates to the zero point.

 

I did mine thru the techstream software. If you do it wrong you will get dash errors.
