Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check ABS Fuse

Locate the fuse box as per the owner's manual.
Use a fuse puller to remove the ABS fuse and inspect it. Replace if blown.

3. Inspect Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Remove the wheel to access the wheel speed sensors.
Clean the sensors and the area around them. Replace any damaged sensors.

4. Check Brake Fluid Level

Open the hood and locate the master cylinder.
Check the brake fluid level; refill with the manufacturer-recommended brake fluid if low.

5. Inspect Wiring and Connectors

Trace the wiring from each wheel speed sensor to the ABS module.
Look for any signs of fraying, cuts, or corrosion. Repair or replace as necessary.

6. Test ABS Relay

Locate the ABS relay in the fuse box.
Use a multimeter to check for continuity. Replace the relay if it fails the test.
