Solution

1. Preparation

Tools Needed: OBD-II scanner, socket set, multimeter, torque wrench, brake fluid.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Scan for Fault Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and record any error codes that appear related to traction control or ABS.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Disconnect the electrical connectors and inspect for dirt or corrosion.
Use a multimeter to test the sensor output; replace if faulty or damaged.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the fluid level is between the "MIN" and "MAX" marks.
If low, top up with the manufacturer-recommended brake fluid.
Inspect for any visible leaks around the brake lines and calipers.

5. Test ABS Control Module

Locate the ABS control module, usually situated near the brake master cylinder.
Inspect the module for signs of damage or corrosion.
Use a multimeter to test the input and output signals; replace the module if necessary.

6. Verify Tire Condition

Check the tire pressure using a tire pressure gauge, ensuring they meet the manufacturer's specifications.
Inspect the tires for adequate tread depth and even wear patterns; replace any tires that are worn or damaged.

7. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any error codes from the system.
Turn the ignition on and check if the traction control light remains off.
