Abs light came on


What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control What it looks like: The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control. How this system works: Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid. Common reasons for this to happen:
  • ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
  • Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working. What to expect: A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. How important is this service? It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

My abs and traction control light is on at the same time


You would need to get the body computer scanned for trouble codes to proceed with testing.
When there is a problem with the abs system, the computer will disable the traction control too since it uses the abs system to function.

Abs and tcs lights on what do they stand for?


ABS stands for anti lock brake system.
TCS stands for traction control system.

I recommend having your abs system diagnosed for faulty sensors, control module, etc. With the abs light on the traction control system is designed to disable because it utilizes the abs system to automatically help control your vehicle in loss of traction situations.

Brake peddle is chattering 2003 ion and would like to pull the anti lock brake fuse (if safe ) until i can afford the repair. I would like to know witch fuse to pull?ABS is on and traction control


If brake pedal is chattering or pulsating it is most likely because you need either front or rear rotors, or both. They are rusted or out of round. If there is something wrong with either your abs or traction control,the abs or traction control light will come on & stay on. As soon as these lights come on, it automatically disables abs or traction control. If you would like to take out fuse that disables abs or traction control circuits, it will leave the lights on.You just wont have their functions. If by some strange condition your chattering goes away, then there is indeed something wrong with your abs or traction control.Fuses are labeled abs or traction either under hood or in your fuse panel in car.

Abs light on and traction control light on


On most vehicles with traction control, the abs system monitors it. If there's a issue with the ABS, the traction control wont work. Check sensors on all 4 wheels and make sure they're not cracked or broken

Engine light and ABS traction control light remain


The ABS sensor is a speed sensor also for Traction Control. This is why both lights are on , One of your front ABS sensors are bad or disconnected, or has a pinched wire.

2001 olds ABS and traction control sensor issue


An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.
