Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check ABS Fuse and Relay

Locate the fuse box (refer to the owner's manual for the specific location).
Remove the ABS fuse and inspect it for damage. Replace if blown.
Test the ABS relay with a multimeter to ensure it is functioning properly; replace if defective.

3. Inspect Wheel Speed Sensors

Raise the vehicle using jack stands and remove the wheel to access the wheel speed sensors.
Clean any dirt or debris from the sensor and the tone ring.
Check the sensor's wiring for any signs of damage or disconnection.
Test the sensor with a multimeter to ensure it is producing the correct voltage.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it off with the manufacturer's recommended brake fluid type.
Inspect for any leaks in the brake lines or around the master cylinder.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light is still illuminated.
Test the ABS functionality by performing a low-speed brake test in a safe environment.
