Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Tire Inspection and Replacement

Sub-steps:
1. Inspect each tire for tread depth using a tread depth gauge; replace tires if tread is below 2/32 inches.
2. Check tire pressure using a tire pressure gauge; inflate or deflate tires to the manufacturer’s recommended PSI.
3. If tires are worn unevenly, consider rotating or replacing them as needed.

Tools Required: Tire pressure gauge, tread depth gauge, jack, jack stands, lug wrench.

3. Suspension and Alignment Check

Sub-steps:
1. Visually inspect suspension components (shocks, struts, bushings) for any signs of wear or damage.
2. If any components are damaged, replace them as necessary.
3. Perform a wheel alignment using an alignment machine to ensure proper handling.

Tools Required: Alignment machine, basic hand tools for suspension components.

4. Traction Control System Test

Sub-steps:
1. Reconnect the battery terminal.
2. Use an OBD-II scanner to check for any fault codes related to the traction control system.
3. If codes are present, follow the manufacturer’s troubleshooting guidelines to address specific faults.

Tools Required: OBD-II scanner.
