Why are the ABS, TC, and Service StabiliTrak lights on?
The ABS, TC, and Service Stabilitrak lights are on. I replaced a rear driver’s side wheel bearing a couple of months ago, so after looking through threads, I also replaced the wheel speed sensor on that hub and cleaned the other wheel speed sensors. All lights are still on. So I took it in to have the code ran and it came up with “No DTC detected”.
Why is my abs and traction control light on?
Your car has sensors that monitor wheel speed and constantly relay information to the ABS and Traction Control system. When any of your tires have low tire pressure, the ECU ends up sensing an abnormal speed. It may send off inaccurate or flawed information to the ABS or Traction Control, which inadvertently activates their warning signals.
When does traction control turn off Service StabiliTrak?
The “Service Stabilitrak” light will usually appear first and then the car will turn traction control off. Once traction control is turned off, the transmission beings to shift very hard and rough.
What does it mean when the TC Lights Come On?
Thus, if there is an issue with the ABS system the TC lights might come on to indicate a problem. If this is the case, you will have to get the ABS system checked out by a mechanic.
What does the Service StabiliTrak warning light mean?
There’s an issue in many GM vehicles where the Service StabiliTrak warning light will turn on and off. Not only does this mean the stability control system isn’t working, but some owners say it comes along with reduced engine power and a jerky transmission. December 27, 2019

What do service ABS and traction control messages mean?
Service ABS/Traction control/Active Handling messages on I have a Base C6 Corvette that is currently giving me “Service ABS, Service Traction Control, and Service Active Handling” messages on my Drivers Information Center. I have taken it to a repair shop and they claim its the right rear wheel speed sensor.
When to use the traction control ( TCS ) light?
The TCS automatically senses when a wheel loses traction at any time and can be triggered automatically as soon as this is detected. Loss of traction most commonly occurs in ice or snow, so the TCS shifts power from the wheel that is slipping to the wheels that are still gripping the pavement well.
Why does my StabiliTrak come on at random?
The stabilitrak and traction control lights come on and service lights for both come on at random. The usually common before I reach 20 mph, and is random. Some days it won’t some days it will. I have stopped turned the ignition off for a few minutes, and restarted and it goes away. Days later its back. I’ve heard the sensors may be dirty or loose.

What does it mean what the ABS light stays on?
An ABS warning light that comes on and stays on could signal a problem with various components in and related to the anti-lock brakes. For instance, special sensors monitor the speed of the wheels. If one or more of these wheel speed sensors are inoperative or defective, the ABS warning light will remain on.
What does the ABS light and traction control light mean?
The traction control computer in your vehicle is the “brain” that controls the entire system. A defect, corroded contacts or water damage in this computer can result in the entire system going offline, which will turn on the TCS warning light. As the TCS and ABS often share a computer, this may affect your ABS system and turn on that light, too.
Why does the ABS light turn on?
An ABS light on is often caused by a damaged wire to the front sensors or the sensors themselves. The light may come and go as the cause is intermittent. You may not have a hard code, the computer only turns the light on at the time it is seeing the problem. You would need to scan it at the time the light is on.
