Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool if it has been running.

2. Inspect and Replace ABS Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel corresponding to the ABS sensor that has failed (refer to diagnostic codes).
3. Disconnect the ABS sensor connector.
4. Remove the bolt securing the ABS sensor to the hub assembly.
5. Pull the sensor out and inspect the mounting area for debris.
6. Install the new ABS sensor, making sure it is seated properly.
7. Reconnect the sensor connector and secure it with the clip.
8. Reinstall the wheel and lower the vehicle.

3. Check and Replace ABS Fuse

Sub-steps:
1. Locate the fuse box (usually under the dashboard or in the engine compartment).
2. Identify the ABS fuse using the diagram on the fuse box cover.
3. Remove the fuse using a fuse puller or pliers.
4. Inspect the fuse for continuity; replace if it is blown with a new fuse of the same amperage.
5. Reinstall the fuse and close the fuse box.

4. Restore Brake Fluid Level

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Remove the cap and check the brake fluid level.
3. If low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
4. Replace the cap securely.

5. Reset ABS Light

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use an OBD-II scanner to clear the ABS error codes.
3. Start the vehicle and check if the ABS light remains illuminated.
