Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools required: OBD-II scanner, socket set, multimeter, brake fluid, and possibly a wheel chock.

2. Inspect and Replace ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller to remove the ABS fuse.
Check the fuse for continuity using a multimeter; replace it if blown with the same amperage rating.

3. Check Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to gain access to the wheel speed sensors.
Inspect each sensor for damage or dirt; clean or replace as necessary.
Verify the wiring harness is properly connected and undamaged.

4. Brake Fluid Check and Replacement

Open the brake fluid reservoir cap and check the fluid level.
If low, add the appropriate type of brake fluid (usually DOT 3 or DOT 4).
If the fluid is contaminated or discolored, perform a brake fluid flush by bleeding the brakes.

5. ABS Module Inspection

Inspect the ABS control module for signs of damage or corrosion.
If necessary, disconnect the battery before working on the electrical connections.
Use a multimeter to test the module’s power supply and ground connections.

6. Reset ABS Light

After repairs are completed, use the OBD-II scanner to clear any fault codes.
Start the vehicle and observe if the ABS light remains off.
