Why won’t my traction control light go off
The traction control system light should illuminate for 1 to 2 seconds and then go out as the vehicle starts and begins to run. If the light stays on, it either means that the system is deactivated, or there is a problem in the traction control system.
What causes traction control light to stay on?
What Can Go Wrong With Traction Control – As with antilock systems, the wheel-speed sensors, wires, connectors, control modules and other components can occasionally conk out or suffer intermittent problems. The sensors, wires and connectors are located at each wheel and live in a hostile environment of potholes, water, snow, dirt, tar, stones, other debris and more, so they take a beating and can fail.
A problem in the system will usually illuminate a dashboard warning light that traction control is disabled and, in some cases, ABS is also disabled. (When ABS is disabled, you should still have normal braking, just without the antilock action.) This is different from momentary illumination of the warning light; the light should always come on for a couple of seconds whenever you start the vehicle as well as when the system detects that a wheel is spinning freely and does its job to improve traction.
Wheel-speed sensors are supposed to detect when one drive wheel is spinning faster than the others — meaning the vehicle is slipping or losing traction. The system will then reduce power and/or apply the brakes to that wheel. Braking the spinning wheel allows the power to go to the other drive wheel or wheels that have more traction.
- This principle is what has allowed ABS-based traction control in some vehicles to take the place of limited-slip differentials, which serve the same purpose.) When traction control is disabled, you’ll have to control tire slippage the old-fashioned way: by lifting off the accelerator.
- In some cases, the warning light may come on because wheel-speed sensors are covered with road grime or debris.
When the traction control warning light stays on, that means you aren’t getting any help from the system to control traction and the system needs to be checked. Unless you’re driving on slippery surfaces, traction control doesn’t come into play, so getting it repaired isn’t as crucial as it would be for disabled ABS or stability, which are arguably more important as safety features.
A driver can prevent most wheel slippage during acceleration by going easier on the gas pedal. Diagnosing issues usually requires a scan tool to read the trouble code that triggered the warning light. Scan tools can help pinpoint what the issues are (such as a bad speed sensor or connector) and at which wheel(s).
Though traction control provides benefits, it can sometimes be an impediment to progress, such as when entering or leaving a parking space with rutted snow. Some systems are so sensitive that at the first sign of wheel slip, they immediately reduce power or apply the brakes so much that you go nowhere.

Can I keep driving with a traction control light on?
While your car is typically safe to drive with the traction control light on, you should not drive it under certain conditions. If the traction control light, anti-lock braking system light, and red brake-warning light are on, your entire braking system may be affected.
Is it safe to drive with traction control light on
Is it Safe to Drive with the TCS Light On? – It is only safe to drive with the TCS light on if it appears when you are losing traction: it means the system is engaging. Driving without traction control can make your vehicle susceptible to spinning out and sliding around on the road.
- It is best to keep your TCS in working condition and enabled in case hazardous weather pops up.
- This allows you to maintain control of your vehicle at all times.
- Driving with your TCS Light on can be dangerous.
- You increase the potential of losing control of your vehicle.
- The TCS helps control the stability and traction of your vehicle, so without it, the vehicle may not handle slick roadways as it should.
If your TCS Light remains on, your safest course of action is to have a certified mechanic perform a system inspection and TCS module replacement if necessary. The statements expressed above are only for informational purposes and should be independently verified.
Will ABS light reset itself
, Do ABS codes have to be reset by a dealer or special machine, or does the light still being on mean there’s still a problem in the ABS controller? TIA! Check that your connectors are inserted properly and wiring is not chafed or kinked. What was the CEL code previously and what is the code now? And what was the ABS “blink” code and what is it now? How long did you wait before reconnecting the battery? And if you don’t have the proper code(s), you may want to send it in for a one hour diagnostic if the ABS light is still on.
Edit. Info from Ford CD, “The amber anti-lock brake warning indicator will come on for numerous reasons. It warns the driver that the anti-lock brake system has been turned off due to a concern that exists in the system. Normal power-assisted braking remains but the wheels can lock during a panic stop while the indicator is on.
Certain procedures must be followed to find the malfunction in this situation. They are outlined in this section. Make sure the diagnostic procedures are followed step-by-step in order as indicated. WARNING: FOLLOWING THE WRONG SEQUENCE OR BYPASSING STEPS WILL LEAD TO UNNECESSARY REPLACEMENT OF PARTS, AND/OR INCORRECT SERVICE.” Last edited: Nov 1, 2006
If the light is still on, you still have a fault. The ABS light will reset itself only when the ABS controller runs and passes all self tests. It does not need and, for the most part, cannot be reset by other means. Steve Last edited: Nov 1, 2006
,(1) How do I initiate the blink codes?, Sorry, I guess my previous reply wasn’t clear. It is a DTC code, not a “blink” code. I was confused with the airbag codes. For the ABS, you need a scanner capable of initiating the program to run through the diagnostics.
Where is the traction control sensor
Part 1 of 1: Replacing the traction control module – Materials Needed
Driver set Plastic sheet or rubber mat Replacement traction control module Rubber gloves Sockets/ratchet Wrenches – open/box-end
Step 1: Disconnect the battery, Always disconnect the negative battery terminal when working on electronic components in a vehicle. Since most of the electronic components work by controlling ground, the worst thing that can happen if the loose negative terminal contacts the body is the circuit is complete.
Tip : Wearing rubber gloves reduces the chances of static discharge between you and the vehicle electronics.
Step 2: Locate the traction control module, In some vehicles it is located under the hood and/or is a part of the ABS control module. Other vehicles may have the traction control module located in the interior or trunk areas. When replacing a module located in an interior/trunk location, be sure to spread a plastic sheet or rubber mat in the areas you will be working.
Modern vehicle electronics are very sensitive to voltage spikes. Placing yourself on plastic or rubber reduces the chance of any static discharge between you and the upholstery/carpeting damaging any electronics. Step 3: Disconnect the traction control module, Once located, unplug any electrical connectors to the module.
Take pictures or use masking tape to label any connectors so you have no questions as to where they belong later. Remove the screws securing the module; typically four screws hold it in place. Step 4: Reconnect the wiring to the new module, With the new module in hand, reconnect all the connectors unplugged from the old module. Step 5: Align the new module in place, When placing the new module on the mounting surface, make sure all orifices on the underside of the module align with all plungers on the mounting surface before pushing it into place. Once in place, replace the mounting screws, being careful not to over tighten.
Step 6: Start the vehicle, Reconnect the negative battery terminal and start the vehicle. The ABS and/or check engine light should flash and then go out. Typically, a few ignition cycles – starting the vehicle, driving it, then shutting down – should clear any faults that may have been stored in the system.
If not, your local auto parts store may be able to clear the codes for you. If you have any traction control issues with your vehicle, schedule a visit from a YourMechanic mobile technician to your home or office today.

Why is my ABS and traction control light on after tire change
1. ABS Light On After New Tires – Many cars come equipped with four different wheel speed sensors – one at each tire location. These components monitor your wheel speed and relay that information to your ABS, or anti-lock braking system. If youre ABS light comes on after installing new tires, it’s likely that one or more of these sensors were accidentally damaged or bumped during installation.
How much does it cost to fix traction control?
Traction control system switch: Traction switch replacement may cost around $111 to $125. This includes labor charges ($56 – $71) and spare parts ($54). Wheel speed sensor: The estimated cost of wheel speed sensor replacement is around $208 to $250, including labor costs ($62 – $78) and parts ($146 – $177).
Is it OK to turn off traction control?
Question & Answers – When turned off, you may notice that your vehicle handles differently than you are used to when driving on slippery surfaces. This is why you should leave your traction control on at all times. You should leave your traction control at all times so that you can benefit from this important safety feature.
You are driving in a region that requires your tires to have chains, and your vehicle’s traction control is interfering with your ability to drive. Your car is trapped in very deep snow, mud or other surface in which your car cannot move out on its own. Turning off traction control while you rock your car may help you drive out faster.
Can tires affect traction control?
Traction control, anti-lock brakes, and stability control are safety features providing tires with a better grip on wet or slippery pavements. Although each is a component of a three-part part system in today’s car, misconceptions arise when people confuse the three or think they perform the exact same function.
- The Difference Anti-lock brakes and stability control work to stop the vehicle, while traction control deals with the opposite, acceleration.
- Anti-lock brakes keep the car from sliding when you apply the brakes, while stability control is designed to bring the car to a smooth stop should you have to jam on the brakes.
Traction control helps the tires maintain contact with the pavement while the car accelerates. It optimizes control so the car doesn’t slip and side if you pass another car. If you’ve ever accelerated from a dead stop on wet pavement and felt and heard the screeching of the tires as they spun in place, you were driving a car that didn’t have traction control.
- Traction control limits this slip so that the car starts moving as soon as moderate constant pressure is applied to the gas pedal.
- How Traction Control Works Traction control depends on electronic sensors to monitor the rotational speed of the four tires in order to determine if any one has lost traction.
These are the same sensors the anti-lock brake system uses, which is probably why people get confused about the two. If the sensors find that one of the wheels is spinning faster than the others, it will automatically pump the brake on that wheel so it can slow down and stop spinning.
When traction control is engaged, you may even feel a pulsing sensation in the acceleration pedal, similar to the pulse in the brake pedal when the anti-lock brake system kicks in. What Traction Control Will Not Do Many people mistakenly trust that traction control will prevent the car from hydroplaning across the surface of a wet road.
Traction control aids in maintaining traction, it does not make a car stop. When the water level on a road interferes with the tire’s grip on the pavement, the car will hydroplane. When driving during or after heavy rain, traction control or not, the best way to maintain control of the car’s wheels is to drive at a slow steady speed.
Traction control, as well as anti-lock brakes and stability control can be negatively impacted by driving on worn-out treads or tires in need of inflation. With tires, as with all things automotive, maintenance is the best prevention against being stranded on the highway. Should you have concerns about your tires, or your car in general, contact us,

Why is my ABS light on and how do I fix it?
What could cause the ABS light to come on? – There are a variety of things that can cause the ABS light to come on and there are some things you can do to identify some of them. Firstly, you should check your brake fluid reservoir to ensure that the levels aren’t too low, as the ABS warning light can be activated if the levels of brake fluid have dropped.
- If this is clearly an issue, you can top the brake fluid up yourself, which should cause the ABS light to go off.
- If this doesn’t work, it’s a clear sign of a more serious problem that you may not be able to see yourself.
- It could be that one or more of the wheel sensors, that feed information back to the ECU, has become damaged in some way.
This could cause it to report abnormal readings, or not report any at all, causing the ECU to report a fault with the ABS. The ABS warning light could also have come on due to a loss of pressure in the braking system, which could be caused by cracks or splits in the brake fluid reservoir or brake lines.
