Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect ABS Wheel Speed Sensors

Remove the wheel and tire to access the wheel speed sensor.
Disconnect the sensor's electrical connector.
Clean the sensor and mounting area with brake cleaner.
Reconnect the sensor and ensure it is securely fastened.
Repeat for all four wheel speed sensors as needed.

3. Check 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 and visually inspect for continuity.
Replace with a new fuse of the same amperage if necessary.

4. Inspect ABS Module

Locate the ABS module, usually mounted near the brake master cylinder.
Check for any fluid leaks or corrosion in the wiring harness.
If corrosion is present, clean the connections using a wire brush.
If the module is damaged, it may need to be replaced.

5. Test Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; it should be between the minimum and maximum marks.
If low, top off with the manufacturer's recommended brake fluid type (typically DOT 3 or DOT 4).
Inspect for any leaks in the brake lines and connections.
