  Low brake fluid  Add some brake fluid until it come to the level  
  Air in ABS system  Bleed the brake line  

Shall we delve into the depths of the solutions together? 

Broken or crimped wire

Repairing a wheel speed sensor wiring harness can be tricky because any corrosion inside the circuit can cause resistance, leading to voltage drops that can trigger false activation complaints.

Even small changes in voltage, measured in millivolts, can cause wheel speed sensors to read the wrong speed, leading to problems in the vehicle’s ABS control module.

Soldering or splicing the wire can also make it brittle, and the constant movement of the wheel speed sensor harness with the suspension and brake system can cause stress that can eventually lead to failure.

Therefore, it is generally better to replace the entire wire harness with a new one instead of attempting to repair it.

Leaks on the brake line

Here are the required tools and steps for fixing leaks on brake lines.

Tools needed:

  • Pipe cutter
  • Tubing bender
  • Compression fittings
  • Brake fluid

First, look for wet spots, corrosion, or damaged areas on the brake line to identify the leak.

By using the pipe cutter, cut out the leaking section of the brake line. Cut it straight and remove any burrs or rough edges.

By using the tubing bender, you can shape the new section of the brake line to match the old one. Make sure it fits tightly and securely in place.

Slide the compression fitting onto the brake line and tighten it with a wrench; but don’t over-tighten it.

After you have repaired it, you have to refill the brake system with brake fluid and bleed the brakes to remove any air bubbles.

Note: It’s important to remember that brake line repairs should only be done by experienced and qualified mechanics, as any mistake could cause brake failure and result in a serious accident. If you’re not comfortable working on your brakes, it’s best to take your motorbike to a professional mechanic.


Problematic ABS sensor

Sometimes the sensor does not work if it is fully covered with a thick layer of dust. So first, try cleaning the ABS sensor, and if that does not solve the issue, you have to replace the ABS sensor.

How to Replace ABS Sensor of Harley Davidson

First Remove the rear wheel of the motorcycle. This will require some tools and may be a bit of a hassle, but it’s necessary to access the ABS sensor.

Locate the ABS sensor on the wheel hub. It will look like a small electronic component attached to the hub with a wire running from it.

Disconnect the wire from the old sensor and remove the sensor from the hub.

Install the new sensor in the same location as the old one and connect the wire to it.

Reinstall the rear wheel, making sure to properly align the brake rotor and sprocket with the appropriate parts.

Test the ABS to ensure it’s working properly. This can be done by turning on the motorcycle and checking to see if the ABS light is off or by testing the brakes in a safe, controlled environment.

Note: If you’re not confident in your ability to do this type of repair yourself, it’s always best to take your motorcycle to a qualified mechanic or dealership to ensure the repair is done correctly and safely.

Low Brake Fluid

Uncap the oil tank and pour some brake oil until it passes the minimum line.

Air in the Anti-lock Braking System

If air enters the ABS, it will be compressed before pressure is applied to the brakes. So, you have to bleed ABS to remove air bubbles.

How to Bleed ABS on Harley Davidson

First, Remove the master cylinder cap and clean out the fluid reservoir, loose the bleeder and attach a hose to it.

Fill the reservoir with fresh brake fluid from an open container and pump the brakes several times and hold the lever down.

Next, open the bleeder and allow the brake fluid to flow through the hose until there are no bubbles.

Then, close the bleeder and, then after releasing the brake lever.

Repeat steps 4-6 until all bubbles are removed and the brake lever feels firm. For the second caliper, follow the same procedure.

After bleeding both calipers, check the fluid level in the reservoir and add more if necessary. Reinstall the master cylinder cap and check the brake lever for proper pressure before riding.

It’s important to note that ABS brakes may require a specialized bleeding procedure, depending on the make and model of the motorcycle. Always refer to the manufacturer’s guidelines for bleeding ABS brakes to ensure proper maintenance and safety.

After identifying and solving the issue that causes the ABS light to turn on, you have to reset the ABS light.

How to Reset ABS Light on Harley Davidson

First, I connected the diagnostic tool or scanner to the motorcycle’s diagnostic port, which may change depending on the make and model of the motorcycle.

Next, I turned on the scanner and followed the instructions displayed on the screen to access the ABS.

I searched for the option to reset or clear the ABS, which had words like “clear codes,” “reset system,” or a similar phrase.

After locating the reset option, I selected it and waited for a short while for the ABS to reset.

Finally, I disconnected the diagnostic tool or scanner from the motorcycle’s diagnostic port after successfully resetting the system  


Where can I find the diagnostic port on my Harley Davidson?

  1. For touring bikes made between 2001 and 2007, the saddlebags for the right side, front, and behind the side cover. Since 2008, the diagnostic port has been on the left side with no other changes.
  2. For all model years of Softail motorcycles, under the seat.
  3. For all model years, behind the rectangular cover on the left side of the bike, below the seat.
  4. For all V-Rod bikes and all model years, either on the left or right side. The area needs to be behind the triangular cover and situated between the forks and the frame.
  5. For XL (Sportster) Bikes from 2007 to 2018, on the left. Look for it behind the side cover and beneath the seat.
  6. For Harley Street Bikes from 2015–2018, see the right side. Look behind the side cover and beneath the seat.

Can I ride my Harley Davidson with faulty ABS?

Yes, you can. Normal brakes will work without any issues. But you lose the benefits of ABS.

How do I know whether my Harley has ABS?

By observing the wheels, you can determine whether a motorcycle has ABS. The ABS sensor, which is a perforated ring between the brake disc and the axle, will be visible if the motorcycle has ABS.

Does ABS reduce stopping distance on Harley Davidson?

ABS’s main advantage is that it prevents the bike’s wheels from locking when you apply the brakes. ABS is not required to reduce braking distance; it improves the bike’s control and stability when braking.


Hope you understand how to reset ABS light on Harley Davidson. First, you have to find the root of the problem before fixing the ABS light. We hope you have received the necessary information to reset the ABS light on your Harley Davidson.
