Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Addressing Error Codes

Reconnect the battery and scan for error codes.
If error codes are present, research and document them. Follow the appropriate steps to resolve each code.

3. Inspect Wheel Speed Sensors

Tools Required: Ratchet and socket set, multimeter.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels for better access to the wheel speed sensors.
3. Visually inspect the sensors for any physical damage or dirt.
4. Use a multimeter to check the resistance of each sensor; it should be within the manufacturer’s specified range.
5. Clean any dirt or debris from the sensors and connectors.

4. Check Brake Fluid Level

Tools Required: Brake fluid.
Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. If the level is low, top it off with the recommended brake fluid type.
3. Recheck for any leaks in the brake system that might have caused fluid loss.

5. Inspect Traction Control Switch

Tools Required: Torque wrench.
Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Remove the switch panel carefully.
3. Inspect the switch for damage or wear; replace if necessary.
4. Ensure all connections are secure.

6. Reassemble and Test

Reassemble any components removed during inspection.
Lower the vehicle and reconnect the negative battery terminal.
Start the vehicle and check if the traction control light is still illuminated.
