Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel.
Remove any dirt or debris from the sensors and connectors with a cloth.
Check for physical damage or corrosion on the sensor wiring.
Reconnect any loose connectors and secure wiring as necessary.

3. Check Brake Fluid Levels

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, top off using the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid is dirty or contaminated, consider a brake fluid flush.

4. Inspect ABS Module and Wiring

Locate the ABS module, typically found near the brake master cylinder.
Check the wiring harness for any frayed or damaged wires.
If damaged, repair or replace the wiring as necessary.

5. Test Traction Control Switch

Locate the traction control switch, often found on the dashboard.
Use a multimeter to test the switch for continuity when pressed.
Replace the switch if it is found to be faulty.
