Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic socket set, brake cleaner, wire brush.
Ensure the vehicle is parked on a flat surface and the engine is off. Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Remove any dirt or debris using a wire brush and brake cleaner.
3. Inspect the sensor wiring for fraying or disconnection.
4. Measure the resistance of the sensor using a multimeter. Compare readings to specifications found in the service manual.

3. Check ABS Control Module

Sub-steps:
1. Locate the ABS control module, typically found near the brake master cylinder.
2. Inspect the module for corrosion or damage.
3. If an error code indicates a software issue, follow the manufacturer's procedure for reprogramming or updating the module.

4. Verify Brake Fluid Levels

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; it should be at the "full" mark.
3. If low, top off with the manufacturer-recommended brake fluid.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and take it for a test drive to see if the traction control light remains off.
