Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Sub-steps:
1. Locate the wheel speed sensors (typically near the brake rotors).
2. Disconnect the electrical connector from the sensor.
3. Use a multimeter to test the sensor's resistance; replace if outside manufacturer's specifications.
4. Remove the old sensor using the socket set and install the new sensor.
5. Reconnect the electrical connector and secure the sensor in place.

3. Inspect and Refill Brake Fluid

Tools Required: Brake fluid (DOT 4 or as specified by the manufacturer), funnel
Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Inspect the fluid level and top off as necessary with the recommended brake fluid.
3. Check for any leaks in the brake lines or around the reservoir.

4. Reset ABS Light and Test

Tools Required: OBD-II scanner
Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear any stored ABS error codes.
3. Start the vehicle and observe the dashboard for the ABS light; it should turn off if the issue is resolved.
4. Take the vehicle for a test drive to ensure the ABS and traction control systems are functioning correctly.
