Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Wheel chocks, socket set, cleaning brush, brake cleaner.
Sub-steps:
1. Loosen and remove the wheel nuts using a socket set.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheel to access the wheel speed sensor.
4. Inspect the wheel speed sensor for any dirt or damage.
5. Clean the sensor using brake cleaner and a cleaning brush.
6. Reinstall the wheel and tighten the nuts to the manufacturer’s specified torque.

3. Check Brake Fluid Level

Tools Required: Brake fluid (if needed).
Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level against the minimum and maximum marks.
3. If low, add the appropriate brake fluid type as specified in the owner's manual.
4. Secure the reservoir cap.
