Why the ABS Light Turn On?

Before heading towards the resetting process of ABS light without a scan tool, let’s look at the reasons for flashing the ABS light.

Damaged Tire Speed Sensor

You will find the tire speed sensor close to the wheel. The responsibility of this sensor is to check the brake’s pressure build to see if the wheel is performing correctly.

If any wheel performs inefficiently than other wheels, the sensor sends a signal to the ABS, and the light turns on.

Unfortunately, this sensor malfunctions over time. Since the distance between the brake and this sensor is not too significant, it is exposed to excessive heat and wears out soon.

When this sensor malfunctions, the ABS light may turn on unnecessarily.

Old Valve & Pump

The hydraulic pump is the other area that is checked by the ABS sensor. The brake’s pressure gets increased when the wheel is too slow due to the hydraulic pump.

If the ABS system finds an issue with the hydraulic pump, the light will turn on. Without further ado, either you have to reset the ABS light or replace the hydraulic pump.

Lesser Amount of Brake Fluid

After pushing the brake pedal, the brake fluid gets transmitted through a small tube connected to the brakes. As a result, the fluid creates pressure on the brake.

If the brake fluid is available with a lesser amount, the brake will stop the vehicle slowly or malfunction.

When the ABS sensor senses that the brake fluid level is inadequate; an inefficient brake is happening, the light will turn on.

In this case, check the level of brake fluid for leaking or wearing off. Also, resetting the ABS system can solve the problem.

Corroded ABS Module

The ABS module wire may get activated without reason if the wire gets rusted. This way, the communication between the speed sensor and the may affect, due to wrong connectivity, the ABS light may turn on.

Even when inspecting your car, if you find a little bit of rust in the AMS module, don’t overlook it; repair the rust.

Step 01: Get a Jumper Wire

First, visit your nearest auto-parts store and grab a jumper wire. You can also call it a service connector adapter kit.

If you are a beginner and entirely unaware of jumper wire, take assistance from the shopkeeper or owner. Ask whether your selected jumper wire is compatible with Data Link Connector.

More importantly, share your car’s make and year. They will assist you in finding the right jumper wire for your vehicle.

Step 02: Locating the DLC Connector

After collecting the service connector adapter kit or jumper wire, the DLC connector needs to be located. Generally, under the car’s glove box, it is located. In a few vehicle models, the DLC connector is positioned underneath the driver side’s adjacent dash.

Additionally, some brands have a DLC connector close to the intake manifold under the hood.

Always look for the DLC connector when you are not driving your vehicle. Thus, you will remain safe from potential accidents.

Step 03: Connecting the DLC & the Jumper

Once you locate the DLC, it is time to connect the jumper wires to the DLC.

The jumper wires consist of a wide connector that can easily be connected to the DLC. Without any hesitation, connect them up.

After you finished connecting, start the vehicle. At this point, the ABS light will start flashing a few times. You can proceed if it happens.

Step 04: ABS System Resetting

So, you have successfully connected the jumper wire. Now, in order to reset the ABS light, you will need to follow the below 4 things.

  • Remember that releasing or accelerating the parking brake is entirely unnecessary when you press down the brake pedal. The DLC area will make a click sound once you provide a single press.
  • Once you hear the click sound, press the brake pedal down for 8 times uninterruptedly. It would be best to accomplish this process within 3 seconds or ASAP.
  • With the above 2 points, you might not see any flashing from the ABS light. If the ABS light still flashes, repeat the above 2 points. The ABS light will stop flashing when you follow the process intently.
  • If you experience that the ABS light is illuminated for a long-time compared to the usual time, it flashes 4-times and switches off. Be sure; ABS light resetting is successfully done.

Finally, jumper wires and other wires need to be disconnected from the DLC. You can now roam around driving your car with peace of mind.
