Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Replacement

Remove the wheel covers or hubcaps, if applicable.
Loosen the lug nuts slightly with a lug wrench but do not remove them completely.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheels.
Inspect each tire for tread depth using a tread gauge; replace tires if tread is below 2/32 inches.
Check for any bulges, cuts, or other damage to the tires that may warrant replacement.
If tires need replacement, install new tires according to the manufacturer’s specifications and torque the lug nuts to the recommended value (usually 76 ft-lbs).
Reinstall wheel covers or hubcaps if applicable.

3. Suspension and Brake Inspection

Visually inspect all suspension components including control arms, bushings, and struts for wear or damage.
If any components are worn, replace them as necessary using appropriate tools and techniques, ensuring all bolts are torqued to the manufacturer's specifications.
Inspect brake pads and rotors for wear. Replace pads if they are worn below 3mm thickness.
Bleed the brake lines if necessary to ensure proper brake fluid levels and air removal.

4. Traction Control System Check

Reconnect the battery after completing physical inspections.
Use an OBD-II scanner to read any diagnostic trouble codes (DTCs) related to the traction control system.
Clear any codes and test drive the vehicle to see if the traction control warning light reappears.
If codes persist, consult a professional for further electrical diagnostics.
