ABS, Traction Control and hill decent control warning lights come on

Today, most new vehicles come with either an ABS or a traction control system. A problem in the ABS or traction control system is usually indicated by a warning light. When the ABS warning light is on, it means that the ABS has been shut down because of a mechanical or electrical failure.

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.

look listen and dance not matter how you performance keep it calp and trust it

this dealer is a joke abs maybe faulty sensor traction control try check the fuse on the fuse box if is blow replace if nothing happens needs a computer diagnostic

well while putting the car on the lift, traction control does not need to be disabled, and will not cause the abs/traction light to illuminate, these cars are known to have terrible wheel speed sensors that are brittle and tend to brake or malfunction for no apperent reason, and the wheel speed sensors are what control your abs and traction conrol units and they are normally what make the light come on on your dash, the warranty on the sensors was prolonged for that reason, so depending on the mileage of your car they might be covered, hope this helps

This is a common problem. The WABCO abs pump has issues with the fluttter valves, there is a repair kit available. Watch out the dealers will try to sell you a whole new unit instead of supplying the repair kit.

It maybe the control unit or just one of the wheel sensors.

hi hope i can help the traction control is controled by signals from the abs system if you lose a sensor imput the abs light will also come it looks like you have a sensor on the blink hope you find this helpful if so please give it a rating thanks pete

This is the Brake Assistance/Electronic Stablilty malfunction light, it is the equivalent of an ABS (antilock brake) / electronic suspension control (traction control, rollover control, electronic suspension control) light. It basically means you have a problem in either your electronic ABS, traction control, or some other advanced electronic suspension control problem... Your car is fine to drive like it is, unless you detect some other driveability issue other than the dash light... (99.9% of the time it's something irrelevant and maybe stupid; that's what you get for driving electronic cars...) Your best bet to get rid of the light would be to get the car to an auto shop with a reader that can read ABS/EBS, brake and suspension codes to really find out why the light is on (usually a wheel speed sensor, or something like it...)
