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.
Because the ABS and traction control often share the same module, a problem with one mechanism might be indicated by a light for both. If the brake system is malfunctioning, the traction control light might come on as a result. The light for your ABS might also come on if the brake fluid is low.
Traction control and ABS often share the same control module and internal self-diagnostics system. This means that sometimes an issue in the ABS can trigger the traction control light to come on.
Press the gas pedal 3 times in quick succession. Then, turn your engine on all the way and let it run for a minute. The TCS and ABS lights should reset and go away if there isn`t any underlying problem with your traction control system.
The primary input of the TCS is the wheel speed sensor. These sensors continuously monitor the speed of each driven wheel and send the data to the ABS and Traction Control System ECU. When a slip is detected between the tire and the road, the TCS regulates brake pressure on the slipping wheel.
One reason your vehicle`s ABS light is on is because it may be sensing abnormally low levels of brake fluid. You`ll be able to notice if your brake fluid is low by the way your car brakes. The braking may seem soft or spongy. However, if the brake fluid is low, you`ll probably see more than just the ABS light come one.
Wheel speed sensors are often called ABS sensors. You`ll find them mounted on the axles of all ABS equipped vehicles. Look for this sensor on your wheel hubs, near the brake rotors. You`ll find the rear wheel speed sensor mounted on the rear axle housing or wheel cylinder.
The anti-lock function will stop working properly, which may increase the distance it takes to safely stop your vehicle. The rear tires will lock, which will increase vehicle swing on turns and may make your vehicle more difficult to control.
In order to operate, your ABS system needs electricity. This is controlled by the anti-lock fuses and relay. The first fuse (a 10 amp fuse) must be good in order for electricity to flow to the relay, and the relay must function to provide power to the second fuse (a 30 amp fuse).
Without ABS, a rapid, hard brake application could cause wheel lockup and loss of vehicle steering control, if the driver does not pump the brakes correctly or limit the brake pedal force to prevent wheel lockup. Therefore, more driver skill is needed to obtain short stops without ABS.”
“If you don`t have anti-locks, hard braking can cause the wheels to lock up, which can send you into a skid. Wheel lockup can result in longer stopping distances and can cause you to lose control,” Rader says.
On all car models, the ESP G419 sensor unit is installed under the left seat.
Faulty ABS Module
The ABS pump in the braking systems tends to carry some braking fluid. Some seals hold it in place, but if they get worn out, it can cause the fluid to start leaking out.
If the ABS system is not functioning properly, then your vehicle is likely to skid, hydroplane and lose traction under heavy braking conditions. The last time you want to find this out is when you need it most in tough conditions, which could lead to an accident on the road.
Does A Faulty ABS Module Drain My Battery? An ABS module failure can cause the ABS pump to run continuously. This can eventually drain out your vehicle battery. To prevent a flat battery or burning out the ABS pump, have your mechanic remove the ABS fuse.
Removing a wheel speed sensor will disable ABS—and sometimes, stability control. If your car has a yaw sensor, you can unplug that for results. You can also try simply unplugging the ABS module, though that could adversely affect your car`s braking performance.
The ABS (anti-lock braking) and ESP (electronic stability program) lights usually come on at the same time because the two systems share components. WHen the lights are on, it means that the controller has seen a malfunction and stored a fault code describing that malfunction.
When the system is damaged or needs a part to replace, it can cost anywhere from $320 to $1,000. The exact cost really depends on your car and the components of its given ABS system.

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.
