Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning solution, soft brush
Remove the wheel covers or wheels as necessary to access the wheel speed sensors.
Carefully detach the sensors from their mounts.
Clean the sensors and their mounting areas with a soft brush and cleaning solution.
Reinstall the sensors, ensuring they are securely fastened.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid tester, syringe, new brake fluid (DOT 4)
Remove the brake fluid reservoir cap.
Use a brake fluid tester to check the condition of the fluid; if it is contaminated or low, replace it.
Using a syringe, extract old brake fluid from the reservoir and refill with new DOT 4 brake fluid.
Replace the reservoir cap securely.

4. Inspect ABS Module

Tools Required: Multimeter, socket set
Locate the ABS module, typically near the master cylinder.
Check the wiring harness for any visible damage or corrosion.
Use a multimeter to test the power and ground connections to the ABS module.
If the module is faulty, replace it with a new unit following the manufacturer's specifications.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the traction control warning light is still illuminated.
Test drive the vehicle to ensure that the traction control system is functioning properly.
