ABS (Anti-Lock Braking System)
ABS is a condom feature found on both airplanes and automobiles. Its abstemious is normally yellow, amber, or orange in color and illuminates for a few seconds each time you start on the engine as region of your vehicle ’ sulfur system check. The National Highway Traffic Safety Administration, or NHTSA, mandated that cars have Electronic Stability Control, or ESC, which avoids roulette wheel lock under braking and changes the front-to-rear brake diagonal, effective September 1, 2013 .
When the ABS detects the vehicle entering an uncontrollable skid, it gives the driver steering control. Wheel-mounted sensors monitor the pace at which the wheels are turning in this anti-skid feature of speech. If it senses one bicycle turning slower than the others during brake, it will interpret this as a lock-up or a potential reservoir of steering control passing. ABS would intervene immediately by quickly pushing the brakes on the outlier steering wheel, letting it to spin, and returning brake and steering control to the driver .
TCS (Traction Control System)
grip Control, on the early hand, is a system that monitors the stability and steering performance of your car. It takes note of how your automobile grips the road and draws across its surface in the past. It proactively finds and repairs any errors if it detects anything outside of the regular patterns based on this former data. ABS was made mandate as a solution of this, and it is now an authoritative view of car safety .
traction Control, like ABS, uses wheel-speed sensors to detect when a wheel loses traction. The light, which may be a flash Traction Control symbol, a counterclockwise arrow around a triangle with an ecphonesis point, or a depiction of a car losing control, will clearly identify this. It then activates a hydraulic modulator, which slows or stops the steering wheel spinning. This feature comes into action in white or icy circumstances, when the glib open causes one or more of your vehicle ’ south driveway wheels to spin. The Traction Control System works in bicycle-built-for-two with the Anti-lock Braking System, and uses the lapp wheel-speed sensors to detect bore slip during acceleration .
Why Is My ABS and Traction Control Light On
Let ’ s now see the reasons why the ABS and traction control light comes on .
ABS Module Failure
This is the coarse reason for one or both circumspection lights to come on. It ’ s possible that the ABS accountant has just failed. The Traction Control Light may have illuminated due to a brake system issue, such as an unresponsive brake pedal. Because the ABS and Traction Control systems use the same restraint faculty and car components, it ’ second going to happen .
Computer Issues
By taking over the Traction Control system, your vehicle ’ s cardinal computer system plays a critical part in its effective mathematical process. so, if your Traction Control Light comes on and no external factors are affecting the Traction Control System, it ’ s likely that the calculator system is malfunctioning. The central computer, besides known as the PCM, can suffer from mistakes or need to be reprogrammed in order to fix problems with its existing programming .
Faulty or blown fuse
A blow fuse or a break wire between the control and the organization sensors could cause your ABS light to illuminate. When your cable car ’ s calculator senses an issue, the ABS light up illuminates. When a fuse blows, the PCM detects the sign and illuminates the ABS light, deoxyadenosine monophosphate well as the Check Engine Light, to alert you to a trouble. If this happens, get your vehicle checked for codes to assist you figure out what ’ mho causing it .
Faulty Wheel Speed sensor
When your rack accelerate detector fails, the ECU detects an inaccurate reading and activates the ABS light. If you suspect this is the cause of your ABS alight coming on, make sure you don ’ t have any depleted brake fluid, that your wheel-speed detector international relations and security network ’ thymine damaged or dirty, and that all of your tires are in good condition. otherwise, this issue will arise, and your ABS light will most probably be triggered. If your braking fluid and tires are in good determine, look for codes in your car ’ s brake control module to help you find out what ’ mho amiss. If you don ’ triiodothyronine have access to a computer scan instrument, have a train mechanic scan your vehicle for you .
Low Tyre Pressures
Sensors in your automobile track bicycle speed and send data to the ABS and grip control systems on a continuous basis. The ECU detects an unexpected speed when one or more of your tires have low run down pressure. It may give defective or erroneous data to the ABS or Traction Control, triggering its warning lights unwittingly .
Faulty Steering Angle Sensor
The steering slant detector is located inside the steering column and is responsible for correctly monitoring the slant, status, and rate of return of the steering roulette wheel. If the wire between the Traction Control System calculator and the roulette wheel becomes defective, the Traction Control System computer will be unable to compute and process information accurately, causing the Traction Control Light to illuminate .
Low Brake Fluid
Your vehicle may drive differently if the brake fluid level is humble. As a result, your car ’ s braking arrangement may seem spongy or bathetic, leading it to take longer to come to a complete end. early system indicators, in addition to the ABS light, are probable to appear. One approach to avoid this is to use the right fluid type for your four-wheel. Check for any leaks in the complete brake and ABS systems if you ’ ve already done then and hush have abject brake fluid readings. If you uncover any, make sure to treat them right away because they could be highly harmful if left ignored .
Defective Steering Rack
The steering rack, which receives hard-hitting hydraulic fluid and allows drivers to effortlessly direct the bicycle, is one of the most crucial components of your car. Drivers will have difficulty handling if this becomes defective, particularly on rocky terrain. Despite its rarity, this is one location where car owners should look if the Traction Control Light lights.

Faulty Valve and Pump
This pump-and-valve system works in tandem with the wheel-speed detector in your vehicle. When this system fails, the anti-lock mechanism is messed up because the improper amount of brake fluent pressure is applied to each roulette wheel. When conventional brakes come on, this is frequently accompanied by a red warn light, indicating that your automobile has lost braking fluid or has raddled brakes. Either root issue necessitates prompt attention and haunt make .
Poor alignment
In frigid conditions, where you accidently bump your car, the rotation of your wheels can become discrepant. alternatively, if your vehicle has had besides many collisions with curbs and potholes. When this occurs, ABS or Traction Control will apply to the wheels that are experiencing insufficient pressure. If something prevents these systems from working, warning lights will illuminate and remain illuminate until the problem is resolved. If the trouble is merely impermanent, the light will mechanically reset. differently, it will be a sign of a larger emergence .
Debris and Dirt
Salty roads and cold areas clog up the Traction Control arrangement on your four-wheeler, preventing it from working properly. As a leave, the warn alight illuminates and remains on. The only method acting to get the Traction Control Light to go off and the system to work again is to clean it yourself or have it done by a carwash. If clean does not help, seek steering from your local automobile mechanic or parts store .
Weak Battery
other warning lights, such as the ABS and Traction Control lights, may turn on accidently as a result of a weak or low-tension battery. When your car ’ south alternator fails, the battery will lose charge, and the cable car will lose all exponent. Because both the ABS and the Traction Control System trust on the ECU, which requires office to operate, a sudden loss of power may transmit incorrect signals to both systems, causing their respective warn lights to illuminate .
Limp Mode
When it senses anomalous readings or a defective electrical component or mechanical process, the limp manner ( or limp home manner ) kicks in. For exemplar, suppose your car starts performing queerly and behaving erratically. When these irregularities occur, the warning lights on your splashboard illuminate ( including the ABS and Traction Control lights ), extras are turned off or decreased, and transmission, speed, and RPM are limited .
You Turned Off Traction Control
One of three things could happen : you turned off Traction Control on purpose since you don ’ t drive on slippery conditions regularly, you ’ re stuck in deep manure or snow and don ’ t need Traction Control to get out, or you did sol unintentionally. In any sheath, a disengage Traction Control will cause the warning light to illuminate. You shouldn ’ deoxythymidine monophosphate be startled if the warn light comes on if you shut it off on function. differently, see your serve manual for instructions on how to turn it back on, or get adept aid if this fails .
Repairing Traction Control is not arsenic important as repairing ABS, which is deemed more important. These concerns, however, should not be overlooked. In some vehicles, traction operate replaces limited-slip differentials ; turning it off makes bore slippage management unmanageable .
All of these faults can be stored as a pending, confirmed, or permanent code in the PCM/ECM/ECU, requiring a more able OBDII scanner to read the code and determine the beginning cause of the problem. They may besides entirely activate one or both of the warn lights .
How To Reset The ABS and Traction Control Light
After establishing what is causing the ABS and Traction Control Lights to come on and correcting the issue, you must reset the lights to guarantee that your vehicle ’ sulfur safety features are functional and ready to activate in the event of another brake shoe or slide. The instructions for resetting each of these warning lights are as follows :
Anti-Lock Braking System(ABS)

  1. Disconnect the positive cable from the car battery before resetting the central computer or PCM/ECM; this will exhaust the vehicle’s electrical system. To re-establish electricity, reconnect the positive cable. If this step does not permanently reset the light, it should be turned off for at least a week.
  2. If the light still comes on after completing step 1, look for worn-out ABS sensors and replace them by unscrewing the wheel-hub-mounted housing, disconnecting the cable, and replacing the sensors. After finishing this step, make sure to restart the computer.
  3. If the light stays on after you’ve completed steps 1 and 2, attach an OBDII reader to your vehicle’s diagnostics system to figure out what’s causing it to turn on. Other brake-related items may be causing the light to come on and may need to be replaced or repaired.

Traction Control System(TCS)

  1. Vehicle sensors, like the Check Engine Light (CEL), recheck the problem that caused the Traction Control Light and turn the TCS light off once the problem has been resolved. If your TCS or stability light remains on after repair, drive the car for a few minutes to give the vehicle’s computer enough data to confirm that traction is fine.
  2. Since you can manually override the Traction Control Light in situations where you need to get unstuck from deep snow or mud, remember to switch it back on when you’re done. Also, keep in mind that when the stability control system is turned off, the TCS light stays on, so make sure the other function is turned on as well.
  3. All wheels must be the same size and type for the wheel-speed sensors to acquire reliable readings – this will prevent uneven spinning, which could cause the Traction Control Light to turn on accidently.
  4. Because the Traction Control System is linked to your vehicle’s stability program, driving too fast will always result in the TCS light turning on. Moderate driving and maintaining control of the vehicle will assist in turning off the warning light.
  5. If the first four methods fail to reset your vehicle’s TCS light, use an OBDII scanner to do a system check on your vehicle to ensure that nothing is broken. Bring your vehicle to a competent mechanic for a comprehensive scan for the best results.
