Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Test Wheel Speed Sensors

Sub-steps:
- Remove the wheel covers to access the wheel speed sensors.
- Disconnect the wiring harness from each sensor.
- Use a multimeter to check each sensor’s resistance (should typically be between 1,000 and 2,500 ohms).
- If a sensor is faulty, replace it with a new one, ensuring proper fitment.

3. Check ABS Module and Wiring

Sub-steps:
- Locate the ABS module, usually near the brake master cylinder.
- Inspect the module for corrosion or loose connections.
- Check the wiring harness for frays or breaks and repair as necessary.

4. Fluid Inspection

Sub-steps:
- Check the brake fluid reservoir for the correct level and fluid condition.
- If the fluid is low or contaminated, perform a brake fluid flush and refill with the manufacturer-recommended fluid.

5. Reconnect Battery and Reset System

Sub-steps:
- Reconnect the vehicle battery.
- Use the OBD-II scanner to clear any error codes.
- Start the vehicle and monitor for the traction control warning light.
