Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery to avoid electrical shorts during repair.

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector for each wheel speed sensor.
Remove the mounting bolt and carefully pull out the sensor from the hub.
Inspect the sensor for damage; replace if necessary.
Install the new sensor by reversing the removal steps, ensuring it is seated properly, and reconnect the electrical connector.

3. Check ABS Module and Wiring

Inspect the ABS module located in the vehicle’s engine compartment or undercarriage.
Check all wiring harnesses connected to the ABS module for any signs of wear or damage.
If necessary, repair or replace damaged wiring.
Reconnect any loose connections and ensure all are secure.

4. Refill Brake Fluid

Inspect the brake fluid reservoir for proper fluid level.
If low, add the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
Bleed the brakes to remove any air that may have entered the system.

5. Reconnect Battery and Test

Reconnect the battery terminals and ensure they are tight.
Start the vehicle and check if the ABS and traction control lights are still illuminated.
Perform a test drive to ensure that the ABS and traction control systems are functioning correctly.
