Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, multimeter, socket set, brake fluid, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Clear Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Follow the scanner's instructions to clear any existing ABS fault codes.
Disconnect the scanner and turn the ignition back on to check if the ABS light has turned off.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate each wheel speed sensor at the wheel hub assembly.
Disconnect the electrical connector and visually inspect the sensor for debris or damage.
Use a multimeter to test the sensor's resistance; compare readings to manufacturer specifications.
Clean or replace any faulty sensors if necessary.

4. Check ABS Module and Wiring

Inspect the ABS control module for any signs of moisture or corrosion.
Check the wiring harness for frayed wires or loose connections.
Repair or replace any damaged components as needed.

5. Brake Fluid Inspection

Open the brake fluid reservoir and check the fluid level and condition.
If the fluid is low, top it off with OEM specified brake fluid.
If the fluid appears contaminated, perform a brake fluid flush and replace with new fluid.
