Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, tire pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors at each wheel hub.
- Remove any protective covers if necessary using a socket set.
- Disconnect the electrical connector from the sensor.
- Remove the sensor from its mount and inspect for damage or dirt.
- If damaged, replace with a new sensor and torque to manufacturer specifications.
- Reconnect the electrical connector and reattach any covers.

3. Check and Refill Brake Fluid

Sub-steps:
- Locate the brake fluid reservoir.
- Check the fluid level against the minimum and maximum markings.
- If low, use the appropriate brake fluid type (DOT 3 or DOT 4) to refill to the maximum level.
- Recheck the fluid level after a test drive to ensure no leaks exist.

4. Test and Replace ABS Module if Necessary

Sub-steps:
- Use a multimeter to check the voltage at the ABS module connector.
- If no voltage is present, trace the wiring back for faults.
- If voltage is present but the module does not function, replace the ABS module.
- Follow the manufacturer’s instructions for installation and programming if required.

5. Tire Inspection and Inflation

Sub-steps:
- Inspect each tire for uneven wear, cuts, or punctures.
- Use a tire pressure gauge to verify that each tire is inflated to the recommended PSI.
- Inflate or replace tires as necessary.
