Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve ABS-related trouble codes.
Record the codes for reference and then clear them.
Reconnect the battery terminal.

3. Inspect Wheel Speed Sensors

Raise the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Inspect the sensor for debris, damage, or misalignment.
Clean the sensor and its mounting area if necessary.
Reinstall the wheel and lower the vehicle.

4. Check ABS Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the ABS fuse and inspect it visually for breaks.
If the fuse is blown, replace it with one of the same amperage.

5. Inspect ABS Module and Wiring

Visually inspect the ABS control module for signs of corrosion or damage.
Check wiring harnesses for fraying, breaks, or loose connections.
Repair or replace any damaged components.

6. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level and condition.
If the fluid is contaminated or low, flush the brake system and refill with manufacturer-recommended brake fluid.
