Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is off.
Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, brake cleaner
Remove the wheel that corresponds to the sensor being inspected.
Locate the wheel speed sensor and disconnect its electrical connector.
Clean the sensor and the area around it with brake cleaner and a brush to remove any debris.
Reconnect the sensor and firmly secure it in place.
Repeat for all four wheel speed sensors.

3. Check Brake Fluid Level

Tools Required: None
Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top off with the manufacturer-recommended brake fluid.
Inspect for any visible leaks in the brake lines and around the reservoir.

4. Inspect ABS Control Module

Tools Required: Multimeter, socket set
Locate the ABS control module, usually near the brake master cylinder.
Use a multimeter to test for proper voltage and ground at the module connectors.
Inspect for any corrosion or loose connections and repair as necessary.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal and ensure it's tight.
Use an OBD-II scanner to clear any error codes that were logged.
Start the vehicle and check if the traction control light remains off.
