Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools, brake fluid, cleaning supplies.
Ensure the vehicle is parked on a flat surface and the ignition is off before beginning repairs.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the ON position without starting the engine.
Retrieve and note down any ABS-related error codes for reference.

3. Inspect ABS Components

ABS Fuse Check:
- Locate the fuse box; refer to the owner's manual for ABS fuse location.
- Remove the ABS fuse and inspect it for continuity using a multimeter.
- Replace blown fuses with the same amperage rating.
Wheel Speed Sensor Inspection:
- Raise the vehicle and remove the wheel to access the wheel speed sensor.
- Inspect the sensor for physical damage and ensure it is clean.
- Check the sensor's electrical connector for tightness and corrosion.
- Use a multimeter to test the sensor's resistance; replace if out of specification.

4. Brake Fluid Inspection

Open the brake fluid reservoir cap and check the fluid level.
If the fluid is low, top it up with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, consider a brake fluid flush.

5. Clear Error Codes

After addressing any issues found, reconnect the OBD-II scanner.
Clear the error codes from the ABS module and turn the ignition off.
Start the vehicle and check if the ABS light remains off.
