Solution

1. Preparation

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

2. Inspect and Replace Fuse

Locate the ABS fuse in the fuse box.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage; if blown, replace with a new fuse of the same amperage.

3. Check Wheel Speed Sensors

Remove the wheel and tire assembly for access to the wheel speed sensors.
Disconnect the sensor's electrical connector.
Clean the sensor with a suitable electrical cleaner and inspect for physical damage.
Reconnect the sensor and repeat for all wheel speed sensors.

4. Brake Fluid Inspection

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the manufacturer-recommended brake fluid.
Inspect for any visible leaks in the brake lines and connections.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and check if the ABS light remains on.
Perform a test drive to assess brake performance and verify if the ABS system functions correctly.
