Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Locate each wheel speed sensor on the front and rear wheels.
Remove any necessary covers or shields to access the sensors.
Check the wiring and connectors for any signs of wear or damage.
Clean the sensors with a suitable electronic cleaner if they are dirty.
Reconnect any loose connectors and ensure they are secured properly.

3. Check ABS Control Module

Locate the ABS control module, typically found near the brake master cylinder.
Inspect the wiring harness for any frayed wires or loose connections.
Use a multimeter to test the power supply to the ABS module.
If necessary, replace the ABS control module following the manufacturer’s guidelines.

4. Brake Fluid Inspection and Replacement

Check the brake fluid level in the reservoir; top up as needed with the recommended fluid type (usually DOT 4).
If the brake fluid is contaminated or old, drain and replace it according to the manufacturer’s specifications.

5. Tire Inspection

Inspect all tires for uneven wear patterns or damage.
Measure the tire pressure with a gauge and inflate to the manufacturer's recommended PSI.
Rotate the tires if uneven wear is found.

6. Reconnect Battery and Reset System

Reconnect the vehicle's battery.
Use the OBD-II scanner to clear any error codes related to traction control.
Test drive the vehicle to ensure the traction control light remains off.
