Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve any stored ABS trouble codes and note them for further analysis.

3. Inspect Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate each wheel speed sensor at the wheel hub assembly.
Clean the sensor area to remove any debris or dirt.
Check for physical damage or loose connections, and replace any faulty sensors.

4. Check ABS Module and Wiring

Locate the ABS module, typically found near the brake master cylinder.
Inspect the wiring harness for fraying, corrosion, or loose connections.
Use a multimeter to test the wiring for proper voltage and continuity according to the manufacturer’s specifications.

5. Verify Brake Fluid Level

Open the hood and locate the brake master cylinder reservoir.
Check the fluid level; if it’s low, top it up with the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid appears contaminated, consider performing a brake fluid flush.

6. Replace Fuses (if necessary)

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse for the ABS system using the owner's manual.
Replace any blown fuses with the appropriate amperage rating.
