Solution

1. Preparation

Gather tools and necessary parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety.

2. Clear Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Follow the scanner's instructions to read and clear ABS fault codes.
Disconnect the scanner after clearing codes.

3. Inspect and Clean Wheel Speed Sensors

Remove the wheel for access (using a lug wrench).
Locate the ABS wheel speed sensor on the hub assembly.
Clean any debris or corrosion from the sensor and its connector with a cleaning solution.
Ensure the sensor is seated correctly and reconnect the wiring harness.

4. Replace Faulty Components

If any components (such as sensors or the ABS module) are found faulty, replace them with OEM or quality aftermarket parts.
Follow manufacturer specifications for torque values when installing new components.
