Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, tire pressure gauge, cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Remove the wheel covers or wheels as necessary to access the wheel speed sensors.
2. Clean any dirt or debris from the sensors and their connectors.
3. Check for physical damage to the sensors and wiring.
4. Reconnect any loose connections and secure the wiring.

3. Check ABS Module Connections

Sub-steps:
1. Locate the ABS module, typically found near the brake master cylinder.
2. Inspect the wiring harness for any signs of wear, corrosion, or disconnection.
3. Use a multimeter to test for continuity and voltage at the module.
4. Secure any loose connections and repair or replace damaged wiring as needed.

4. Verify Tire Condition

Sub-steps:
1. Use a tire pressure gauge to check each tire’s pressure, adjusting to the recommended levels.
2. Inspect each tire for uneven wear or damage that could affect traction.
3. Replace any tires that do not meet safety standards or specifications.

5. Reset Traction Control System

Sub-steps:
1. Reconnect the vehicle's battery.
2. Start the vehicle and access the vehicle’s settings from the dashboard interface.
3. Navigate to the traction control settings and perform a reset if available.
4. Drive the vehicle to ensure the traction control light does not reappear.
