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.
If you are driving in slick conditions on snow and ice or on wet pavement, this could be NORMAL OPERATION. The lights are coming on to let you know that the Traction Control System (TCS) and the Antilock Brake System (ABS) is actively correcting a wheel slip condition.
If this is happening on dry pavement, and you are not driving like a maniac, (making the wheels slip and slide) then there is possibly a problem with one of your wheel speed sensors that is making your TCS and ABS computers "think" that there is a wheel slipping. You will have to scan your computer system and watch the wheel speed sensor data to find out which one is malfunctioning.
the abs warning light also works with the electronic traction control, (or traction control,same system,different names) and when icy, stops the wheels from spinning,above about 15 mph.(the abs dont work under 5mph) so if im right regarding your question,your car is doing what its supposed to,stopping the driving wheels from spinning/locking up.the warning light comes on when one or the other is doing its job.(working).the trick is to drive so that the warning light doesnt come on..... boring.
This is the Traction Control Warning light. Traction control is device added to the engine/gearbox sytem, and is designed to help minimise wheel spins when moving away, particularly on a slippery surface. When the system detects the wheels starting to slip and Traction control starts to cut in this warning light shows.
Traction control cannot do much to help in severe ice or snow though, so you can expect to see this light showing or flashing if the conditions are extreme.
If this light shows when the conditions are not extreme, stopping and restarting the engine will often reset it.
The problem is most often caused by a defective wheel speed sensor for the ABS and traction control, there are four of them, it may be they are dirty or defective, take the wheels off the car (use safety stands) and follow the wires that go to wheel hub, at the end of the wire harness you will find the sensors, remove them (carefully, don't p[ull on the wires) and look for metal flakes attached to them, they are magnetic pickups so this metal can corrupt the signal and turn the waring light on, if they are clean then you will need the dealer to test the system for the trouble code that is present whenever the ABS/TC warning light is on, the parts are very expensive so guessing is very bad idea.
You are loosing power Because the Computer is Shifting the Transmission in to Traction Low to get out of the Situation. The ABS Light is coming on due to Wheel spin. It is telling you that there has been an Unexpected Incident and to slow down.
