Solution

1. Preparation

Gather necessary tools and equipment, including an OBD-II scanner, basic hand tools, and a clean cloth.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Address Error Codes

Use the OBD-II scanner to read any stored error codes.
Document the codes and clear them from the system.
Monitor if the traction control error returns after resetting.

3. Tire Pressure and Condition Check

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires to match the recommended levels found in the owner’s manual or on the driver's side door jamb.
Inspect tires for uneven wear or damage, replacing tires if necessary.

4. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensors using a clean cloth.
Ensure all electrical connectors to the sensors are secure and free of corrosion.

5. Update Software

Navigate to the vehicle settings and check for any available software updates.
If an update is available, follow the on-screen prompts to complete the installation, ensuring the vehicle remains connected to Wi-Fi during the process.

6. Check ABS Module and Wiring

Inspect the ABS control module for any physical damage or loose connections.
Examine the wiring harness leading to the module for any signs of fraying or disconnection.
Repair or replace any damaged components as necessary.
