Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, safety gloves.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensors and connectors.
Check the wiring for fraying or breaks.
If damaged, replace the sensors with new ones.
Torque specifications: Follow manufacturer specifications for reinstallation.

3. Examine ABS Control Module

Locate the ABS control module, typically found near the brake master cylinder.
Check for loose or corroded connections.
If no visible issues, use the OBD-II scanner to clear any fault codes and test drive the vehicle to see if the light returns.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the appropriate brake fluid type (usually DOT 3 or DOT 4).
If dirty or contaminated, perform a brake fluid flush and replace with new fluid.

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 defective, replace the switch.
