Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Wheel Speed Sensors

Locate the Wheel Speed Sensors: Access the wheel wells to find the sensors mounted near the brake rotors.
Remove the Sensors:
- Disconnect the electrical connector.
- Unscrew or unclip the sensor from its mounting point.
Inspect the Sensors:
- Check for cracks, dirt, or damage.
Replace if Necessary:
- Install the new sensor by reversing the removal steps.
- Ensure the connector clicks securely.

3. Check and Replace ABS Fuse

Locate the Fuse Box: Refer to the owner’s manual for the fuse box location.
Identify the ABS Fuse: Use the diagram on the fuse box cover to find the ABS fuse.
Inspect the Fuse:
- Remove the fuse and check for continuity with a multimeter.
Replace if Blown:
- Install a new fuse with the same amperage rating.

4. Brake Fluid Inspection and Replacement

Check Brake Fluid Level:
- Verify that the fluid level is within the recommended range.
Flush Old Brake Fluid:
- Use a brake bleeder kit to remove old fluid from the system.
- Replace with new DOT 3 or DOT 4 brake fluid as specified in the owner’s manual.
Bleed the Brakes:
- Start from the farthest caliper to the closest, ensuring no air remains in the system.

5. Reconnect Battery and Test

Reconnect the Negative Battery Terminal:
- Ensure it is tight and secure.
Start the Vehicle: Check if the ABS light is still illuminated.
