These keep poping up while driving

While i am driving these lights come "Service Vehicle, ABS Inoperable, Brake, TCS Off" this randomly happens while i am driving and idk if i can get the Service vehicle code read, and idk what is wrong or wat i need to do I r very very scured =X can someone help me plz. I assume it is something to deal in the Rear differential area but idk cuz i just know those three things all deal back there. Is it borked? I can still brake and use it, but i am afraid cuz i freaked out when i saw SES light n went and got new O2 sensors just so i wouldnt have to worry about it coming on

Have those pop up periodically when I get done with a pass at the track and I am particularly hard on the brakes. Subscribed

=x it is just my daily driver, n it comes on at random moments, no hard braking or launching, just driving around, there is new pads and rotors, n it has me very scurred. like it sometimes does it when i just start the car, the scariest time was when i was goin into a hairpin turn, n it was the first time the car did that there was no hard braking, but seeing TCS off right on those turns when u need it most is kind of scary especially when there is a deep ditch full of water taunting you ;.;

You need to have your ABS codes scanned. You most likely have a wheel speed sensor that is going bad.

Well it stopped doing that today =X or atleast it didnt do it once today, but i did do something different, cuz i hadz a bad day n new tires r coming in soon~

And how do u change one of dem? tire speed checkin thingmajjigers

Mine had the same problem
I replaced the speed sensor
And the light still there
I was pissed

does everything else work when that happens?
Check your ABS block connector just to make sure it isn't burned up. I fixed a car that had that kinda issues and the ABS block connector had a short in it and burned the internals and shorted out a bunch of stuff. In that case, even the gas gauge and tach stopped working. Replaced the connector and the electronic portion of the ABS block and it fixed it all.

Depends on which one is bad. Have you had the codes scanned yet? The front 2 sensors require you to replace the whole wheel bearing and hub assembly. The rears are just an easy sensor to unbolt from the rear axle.

Yeah but you had 2 codes and 2 problems. Hehehe...you didn't believe me did you? I told you you had 2 problems :).

Yeah I remember that lol
1 problem was the speed sensor
And the other one was the abs unit I think
But the guy said it was only the speed sensor

lol it's funny but i had those light then i changed my pulleys and than again when i had alternator problems cuz it was giving a high charge

I have a 2001 WS6 that displays ABS INOP, TCS Off, Brake, and Security intermittently. Is this the same problem? Any suggestions?

ABS INOP, TCS Off, and Brake lights are related. You need to have the ABS computer scanned for codes.

Will do. Thank you
