Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shocks.
Ensure the vehicle is on a flat surface and securely lifted if needed.

2. Inspect and Clean ABS Wheel Speed Sensors

Remove the wheel where the sensor is located using a lug wrench.
Locate the ABS wheel speed sensor; it is usually mounted near the brake rotor.
Clean the sensor and the surrounding area with brake cleaner to remove any debris or corrosion.
Reinstall the sensor and wheel, tightening lug nuts to the manufacturer's specified torque.

3. Check and Replace ABS Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the ABS fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers; inspect for any signs of damage.
If blown, replace with a new fuse of the same amperage rating.

4. Brake Fluid Inspection and Replacement

Check the brake fluid reservoir for proper fluid level; top off if necessary with the recommended brake fluid type.
Inspect brake lines for leaks; replace any damaged lines.
If fluid is contaminated, perform a brake fluid flush using a brake bleeder kit.

5. Test the ABS Module

Reconnect the battery and turn on the ignition without starting the engine.
Use a multimeter to check for power and ground at the ABS module's connector.
If there’s no power, trace wiring back to the battery or fuse box for faults.
