FAQ: Anti-Lock Brakes and/or Traction Control Light/Lamp On

Might try cleaning the connectors on the hubs/sensor wires. It's a long shot, but pretty easy to do.


MOVED TO: SUSPENSION & HANDLING

usually it's the sign of a dying wheel speed sensor. Eventually it will stay on all the time.

Mine started coming on after going through a puddle, and eventually graduated to on all the time. Time for new wheel bearings... 143K is a good amount of miles on the stockers. Usually people start reporting WSS issues around 120K

Now I took mine to the freakin shop and they charged me a $100 to tell me I need a new EBTCM.

How do you tell if a wheel speed sensor is bad? Because a new EBTCM is over a grand and not worth having. But a new wheel speed sensor from e-bay is $90..

???

ought to be $175 - $300 used on ebay or via Ed Morad - use Search on this Bboard to find address for Ed.

I got new, GM bearings/hubs/wss for $143 from monsterpartsonline.

Nate what year is your Riv?

I had a problem on my '95 and it turned out being a corroded connection, but I would take a look at all of the connections.

Mine's a 96. I've taken each hub plug and greased it a couple of years ago.

My light always goes on about 15 seconds after running. However, sometimes I can go miles without stopping and it stays off. But when I start again, 15 seconds or so later, the light goes back on.

I know it doesn't work even with the light off, in the snow I would purposely try to spin the wheels...no traction control at all....

You are losing a Wheel Speed Sensor. You'll be replacing the entire hub to fix it. I recommend doing both, because if you don't you'll be doing the other side next year, plus you don't have to pay somebody to hook up an ABS capable computer to find out which side is gone.

Hi I am new to this site, I have a few problems with my 95 riv, My abs and traction amber lites stay on all the time. I changed the hubs thinking this would solve problem, well it didnt, I use the 95 riv shop manual, and have gone step by step in trouble shooting, cant find problem?? Does anybody out there know if the new Actron ABS reader will work on the 95 rive? I know its OBD 1 with a 16 pin OBD 11 connector, need a little imput thanks willy

My light stays on too...

When I first start the car in the morning, the light is off.....then a few minutes later the light comes on.

If I go on a long road trip, 300 miles or so.....it turns off and I can turn it on and off via switch...then when I return to my normal routine the light turns on again....

I think when I get my PCM I'm just gonna have them turn off the traction control....

my friend has a snap on "brick" scanner and he was able to pin point the problem with that on mine , pass wheel bearing

yah i have a "snap-on brick scanner" too, that will definitely pin point the problem. if you're close to the st. louis area i'll scan it for you. if not, then you might wanna check your abs wires to the wheel sensors themselves and also check the abs/traction control pump. then there is also a an abs module and traction control module. take it to the dealer and pay the $100 to have them find out the problem.

the other day my tc and abs light popped on...car still has brakes, and all that shit i was wondering if anyone got any insight on this subject...thanks

would help to know what year and stuff your car is. Please add that info to your signature.

Usually it's a wheel speed sensor, which means a wheel bearing needs to be replaced. Unfortunately you need someone with an ABS scan tool to pull the code.

I got A 97 Riv SC and when I bought it my traction control light was on indicating that it was off, is this a bad thing? I mean i dont have to push the button to turn it of, it dont bother me except for the light being on all the time. But is it a problem ??

Usually it means a wheel speed sensor is shot, which is a preindicator of wheel bearing failure. If you find out which wheel it is, then replace the bearing (sensor is included in the bearing). Need the code read by an ABS specific scan tool.

so I need a scan to find out what side or should I just replace both sides

I paid a shop $30 to tell me which bearing wasn't reading...

ok kool but would it be better to just replace both so i dont have the problem of fixing one and then the other goes out? and how much are wheel bearings?

There should be a sensor for each wheel. I bougt one for the rear of my '96 a couple years ago and it was $180 so you'll probably want to get it scanned first to see which one is bad.

ok kool thanks for the advice

i got the same the same prob on my 97 riv sc

yah i agree with Derek. the problem is normally found where the wheel sensor hooks up. if you can jack up all four wheels with the tires off so that you can look at each sensor. you could also have a busted up outer cv boot thats leaking grease all over the sensor. if thats the case, then you will have to clean off all the grease with a good degreaser, and replace the half shaft. you will have to find sumone with a scanner that is capable of testing the abs system. NOT ALL SCANNERS CAN!

the tract light is tc light is on because the abs light is on. once you fix the abs light then the tc light will go off.

any mechanic should have one correct?

shit sorry guys its 96 SC RIV.....THANKS FOR THE HELP LET YA KNOW HOW IT GOES
