Default VSC and VSC OFF light came on...

ok, so i know this is a "common" problem w/2nd gen GS's... but usually i see posts that include the CHECK ENGINE LIGHT as well... in my cae, that light did not/has not come on. the VSC & VSC OFF light come on at very random times and if i pull over and turn the car off, the lights wont come back on... the thing that worries me is that when those come on, the RPM needle jumps up and down on its own someone help me

I have been having battery troubles lately and when I come out in the morning to start the car for the first time if it has some difficulty cranking over I have noticed those two lights come on and stay on. That is until the next time I start the car and they do not come back on. I have associated it with the bad battery and the weak start. Just a thought from my experience.

they can pull up codes even if the CEL is not on i didnt know that... the next time it happens, ill have to run to autozone so they can pull the codes up b/c if i turn the car off, the lights usually dont come back for a while.

i honestly dont think that the battery is the problem. i did change it a few years ago (maybe 3 yrs ago) and i never had a problem at the crank. the lights come on while im driving usually

Hmmm sorry I couldn't be more help. I was hoping it would be an easy fix for you, but I've never had them turn on while I was driving.

Did you do any suspension mods lately? Or anything near the suspension? Reset ECU overnight....check all fluid levels...even differential fluid level.

no suspension mods lately but how do i check the differential fluid level and what other fluids should i check specifically. also, keep in mind that the RPM needle jumps up and down on its own when those lights come on

the VSC lights on my 99 gs4 came on and suddenly the car slowed down. My RPM needle dropped too. I mean like I had the gas all the way down and nothing. It came on because the throttle sensor is part of that system and that was the problem. If your ride starts to slow down after the light turns on its that. $240/ part .

Check your ABS Sensor . When I had my Balljoints replaced the mechanic managed to "yank" on the ABS Sensor accidentally and the VSC, ABS and Traction lights were on the dash. Let me know if that works .
