Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a level surface and secure it with jack stands if lifting is required.

2. Address Fault Codes

Sub-step 1: Connect the OBD-II scanner and read the fault codes.
Sub-step 2: Document any codes and clear them after repairs to see if they return after a test drive.

3. Inspect and Replace ABS Components

Sub-step 1: If wheel speed sensors are faulty, remove the wheel and locate the sensor.
Sub-step 2: Disconnect the wire harness and remove the sensor using the appropriate socket.
Sub-step 3: Install the new sensor, ensuring it is properly aligned and secured.
Sub-step 4: Reconnect the wiring harness and repeat for all affected sensors.

4. Check Brake Fluid Level

Sub-step 1: Locate the brake fluid reservoir and check the fluid level.
Sub-step 2: If low, add the appropriate brake fluid (DOT 3 or DOT 4, as specified in the owner's manual) and securely close the reservoir cap.

5. Test Drive and Final Checks

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the vehicle and observe the dashboard for the ABS light.
Sub-step 3: Take the vehicle for a short test drive to ensure the ABS system is functioning correctly and the light does not return.
