Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to prevent electrical shock.
Ensure the vehicle is on a level surface and secured with wheel chocks.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Jack and jack stands, socket set, multimeter
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel where the sensor needs to be checked.
Visually inspect the wheel speed sensor for damage or disconnection.
Use a multimeter to check the sensor's resistance; it should be within the manufacturer’s specified range.
If the sensor is faulty, disconnect the wiring harness and remove the mounting bolt.
Replace with a new wheel speed sensor and secure it properly. Reconnect the wiring harness.

3. Check Brake Fluid Level

Tools Required: None
Locate the brake fluid reservoir under the hood.
Check the fluid level and condition; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer's specified brake fluid type.

4. Verify and Test ABS Functionality

Tools Required: OBD-II scanner
Reconnect the battery and turn on the ignition.
Use the OBD-II scanner to check for any ABS-related error codes.
If ABS codes are present, follow the manufacturer's guidelines to troubleshoot and resolve any identified issues.

5. Check Tire Condition and Pressure

Tools Required: Tire pressure gauge
Inspect all tires for uneven wear and damage.
Use a tire pressure gauge to check the pressure; inflate to the recommended PSI if necessary.
