Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Remove the wheel on the affected corner.
Locate the wheel speed sensor on the wheel hub.
Clean the sensor and the area around it to remove debris.
Check the sensor's connector for corrosion; clean or replace if necessary.
Reinstall the wheel and lower the vehicle.

3. Check ABS Fuse

Locate the fuse box (consult the owner’s manual for location).
Remove the ABS fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with a fuse of the same amperage rating.

4. Inspect ABS Wiring

Trace the ABS wiring harness from the wheel speed sensors back to the ABS module.
Look for any signs of fraying, cracking, or damage.
Repair or replace damaged wiring as necessary.

5. Check Brake Fluid Level

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 leaks around the brake lines or master cylinder.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS error codes.
Test drive the vehicle to check if the ABS light remains off.
