Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery to prevent any electrical issues during the repair.

2. Retrieve Fault Codes

Use an OBD-II scanner to check for ABS-related fault codes.
Document any codes for reference when diagnosing.

3. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any debris or dirt surrounding the sensors.
Clean the sensor using a soft cloth and brake cleaner.
Reattach the sensor securely.

4. Check Wiring and Connections

Visually inspect the wiring harness connected to the ABS control module and wheel speed sensors.
Repair or replace any frayed or damaged wires.
Ensure all connectors are tight and free from corrosion.

5. Brake Fluid Check

Inspect the brake fluid reservoir for proper fluid level.
If low, add the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).
Replace any contaminated fluid by bleeding the brakes.

6. Test the ABS Pump

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Listen for the ABS pump to activate (a faint buzzing sound may be heard).
If the pump does not activate, further diagnosis may be required for the ABS control module.

7. Clear Fault Codes

After completing repairs, use the OBD-II scanner to clear any fault codes from the system.
Test the ABS light to confirm it has turned off.
