Range Rover EBD fault warning sign

One warning sign that tends to cause panic among many Range Rover owners is the “EBD Fault” warning light.

The Range Rover EBD (Electronic Brakeforce Distribution) fault warning sign indicates a potential issue with the system that proportionally distributes braking force to each wheel. Causes can range from sensor faults to mechanical issues. Professional diagnosis is advised for accurate resolution.

This warning light is one of the most common warning signs that Range Rover owners experience and it is important to understand what it means and how to fix it.

What models are affected?

Signs and symptoms

When the EBD Fault warning light appears on your car’s dashboard, it is often accompanied by other warning lights such as the ABS and Traction Control lights.

You may also experience the following symptoms:

  • The brake system may feel less responsive than usual.
  • The car may pull to one side when braking.
  • You may hear unusual grinding or scraping noises when applying the brakes.

List of possible OBD codes

When the EBD Fault warning light appears on your Range Rover’s dashboard, it is likely that one or more of the following OBD codes will be stored:

  • C1093 – Brake Fluid Pressure Sensor Circuit Range/Performance
  • C1094 – Brake Fluid Pressure Sensor Circuit Low
  • C1095 – ABS Hydraulic Pump Motor Circuit Failure
  • C1138 – ABS Hydraulic Pump Motor Circuit Open
  • C1139 – ABS Hydraulic Pump Motor Circuit Short to Ground
  • C1175 – Brake Fluid Pressure Sensor Input Malfunction
  • C1176 – Brake Fluid Pressure Sensor Input Malfunction

Common causes

There are several potential causes of EBD Fault warning light on your Range Rover.

Here are some of the most common causes:

  • Faulty Brake Fluid Pressure Sensor: The brake fluid pressure sensor is responsible for monitoring the brake fluid pressure in your car’s brake system. If it fails, it can trigger the EBD Fault warning light.
  • Faulty ABS Hydraulic Pump Motor: The ABS hydraulic pump motor is responsible for pressurizing the hydraulic brake system. If it fails, it can trigger the EBD Fault warning light.
  • Low Brake Fluid: If the brake fluid level is low, it can trigger the EBD Fault warning light.
  • Worn Brake Pads: If the brake pads are worn, it can cause uneven braking and trigger the EBD Fault warning light.
  • Brake System Contamination: If the brake system is contaminated with water or other substances, it can cause the brake system to malfunction and trigger the EBD Fault warning light.

Can it be fixed without a mechanic?

While some causes of the EBD Fault warning light may require professional diagnosis and repair, there are a few steps you can take to fix the problem yourself:

  • Check Brake Fluid Level: Check the brake fluid level and refill as needed. Low brake fluid level can cause the EBD Fault warning light to appear.
  • Check Brake Pads: Inspect the brake pads for wear. Replace worn brake pads as needed.
  • Clean ABS Sensors: Check for debris or dirt buildup on ABS sensors. Clean them with a soft brush or cloth.
  • Reset the ABS System: In some cases, resetting the ABS system can turn off the EBD Fault warning light. To do this, turn off the engine and remove the key for a few minutes. Then, restart the car and see if the warning light disappears.

If none of these steps work, it may be time to take your car to a mechanic.

How to fix it

If you’re comfortable working on your car, you may be able to fix the EBD Fault warning light yourself.

Here’s a step-by-step guide:

  1. Turn off the engine: Turn off the engine and remove the key.
  2. Locate the Brake Fluid Pressure Sensor: The brake fluid pressure sensor is typically located near the brake master cylinder. Unplug the sensor.
  3. Replace the Brake Fluid Pressure Sensor: Use a socket wrench to remove the old brake fluid pressure sensor and install the new one in its place.
  4. Replace the ABS Hydraulic Pump Motor: If the hydraulic pump motor is faulty, you’ll need to replace it. This is a job best left to a professional mechanic, as it can be complicated.
  5. Replace the Brake Pads: If the brake pads are worn, remove the old pads and install new ones.
  6. Bleed the Brake System: Once you’ve made any necessary repairs, bleed the brake system to remove any air or fluid that may have gotten into the system.
  7. Check the Brake Fluid Level: Check the brake fluid level and refill as needed.

Potential alternative causes

While the causes listed above are the most common reasons for the appearance of the EBD Fault warning light, there may be other causes as well. For example, a faulty battery or alternator can cause power fluctuations that trigger the warning light.

If you’re unsure what’s causing the warning light to appear, it’s best to take your car to a professional mechanic for diagnosis.
