2. Address Faulty Wheel Speed Sensors

Sub-steps:
1. Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
2. Remove Wheel: Take off the wheel corresponding to the sensor that is malfunctioning (refer to OBD-II codes).
3. Inspect Sensor: Locate the wheel speed sensor, unplug it, and check for physical damage or dirt buildup.
4. Clean Sensor: If dirty, clean using brake cleaner and a cloth.
5. Test Sensor: Using a multimeter, check the resistance of the sensor. Replace if out of spec.
6. Reinstall: Reconnect the sensor, reinstall the wheel, and lower the vehicle.

3. Check and Replace Brake Fluid

Sub-steps:
1. Inspect Fluid Reservoir: Open the brake fluid reservoir and check the fluid level and condition.
