Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the ABS fuse and inspect it for continuity using a multimeter.
Replace the fuse if it is blown with a new one of the same amperage.

3. Check and Clean Wheel Speed Sensors

Lift the vehicle and remove the wheels to access the ABS wheel speed sensors.
Inspect the sensors for dirt or damage.
Clean the sensors with a soft cloth and a suitable cleaner (e.g., brake cleaner).
Reinstall the sensors and wheels, ensuring they are torqued to manufacturer specifications.

4. Inspect Wiring and Connectors

Examine the wiring harnesses for any signs of wear, fraying, or disconnection.
Clean any corroded connectors with electrical contact cleaner.
Repair or replace any damaged wiring as necessary.

5. Replace Brake Fluid (if necessary)

Check the brake fluid level in the master cylinder reservoir.
If low, add the appropriate type of brake fluid (DOT 3 or DOT 4, as specified by the manufacturer).
If the fluid appears contaminated, perform a complete brake fluid flush.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored codes and reset the ABS system.
Start the vehicle and check if the ABS light remains off.
