why does my Ford F-150 14th Generation (2021-2024) ABS light keep coming on

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve and Clear Error Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Retrieve any stored ABS trouble codes and note them.
• Clear the trouble codes and monitor if the ABS light reappears after driving.

3. Inspect and Replace Wheel Speed Sensors

• Locate the wheel speed sensors at each wheel hub.
• Disconnect the wiring harness from the sensor.
• Remove the sensor using a socket wrench (be mindful of torque specifications).
• Clean the mounting area and install the new sensor, ensuring it is properly seated.
• Reconnect the wiring harness.

4. Check and Replace ABS Fuse

• Locate the fuse box (refer to the owner's manual for the exact location).
• Identify the ABS fuse and check it for continuity using a multimeter.
• If blown, replace it with a fuse of the same amperage rating.

5. Inspect Brake Fluid and System

• Check the brake fluid level in the master cylinder reservoir.
• If low, add the manufacturer-recommended brake fluid.
• Inspect brake lines for leaks and ensure all connections are tight.

6. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and check if the ABS light is still illuminated.
• Take the vehicle for a test drive to ensure proper braking function and monitor for ABS light activation.
