Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor connectors carefully.
Clean the sensor area with a soft cloth and brush to remove dirt or debris.
Reconnect the sensors and ensure they are securely fastened.

3. Check and Replace Brake Fluid

Inspect the brake fluid reservoir for the correct fluid level.
If the fluid is low or contaminated, remove the reservoir cap.
Use a turkey baster to remove old brake fluid.
Refill with manufacturer-specified brake fluid (e.g., DOT 3 or DOT 4).
Replace the cap securely.

4. Inspect ABS Module Connections

Locate the ABS module, usually near the brake master cylinder.
Check all wiring connections for tightness and signs of corrosion.
If any connectors are loose or corroded, clean and secure them.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
If the switch is faulty, replace it with a new one.

6. Reconnect Battery Terminal

Reconnect the negative battery terminal securely.
Start the vehicle and check if the traction control light remains illuminated.
