    Installed 5100s on my 2019 sr5 front and VSC light is on but no other light. It is still on after alignment and zero point calibration, there are no steering issues or anything related, vehicle drives perfect. I will get it scanned when I have a chance but for now wanted to see if anyone else has had this issue with no other dash light on and what their fix was. Thanks!

    The first question that comes to mind is what setting did you use on the front shocks?

    Good point. I used the 1.75" setting. I also installed 5100s on the rear and b12 springs but the light was on after the front before even getting to the rear.

    I belive the vsc system is tied to the wheel speed sensors. Could you have perhaps damaged or stretched one of the front ones during install?

    That height shouldn't have caused any issues. It sounds like a sensor either got unplugged or damaged. I found this bit of information on

    Got it cleared. Had to do ZPC again but this time when I was at the point of both the ABS and Slip light flashing fast I needed to press the DAC and A-Trac buttons to get them to show on the dash. Once I did that and restarted the vehicle, all was clear. The code being thrown was the infamous c120a
