Solution

1. Preparation

Gather necessary tools and parts: OBD-II scanner, multimeter, basic hand tools, and replacement components if needed.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Retrieve and Analyze Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and record any ABS-related trouble codes.
Research codes to determine the exact issue.

3. Inspect and Replace Components

ABS Fuse
- Locate the fuse box and identify the ABS fuse.
- Remove the fuse and check for continuity using a multimeter.
- Replace with a new fuse if it is blown.
Wheel Speed Sensors
- Raise the vehicle and remove the wheel to access the wheel speed sensors.
- Clean any dirt from the sensor and its mounting area.
- Check sensor wiring for any damage or disconnections. Replace the sensor if faulty.

4. Brake Fluid Check and Replacement

Locate the brake fluid reservoir and check the fluid level.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, flush the brake system and replace with fresh fluid.

5. Clear Codes and Test Drive

After repairs, use the OBD-II scanner to clear any trouble codes.
Start the vehicle and take it for a test drive to ensure the ABS light does not re-illuminate.
