Solution

1. Preparation

Gather tools needed: OBD-II scanner (compatible with Tesla), tire pressure gauge, and a multimeter.
Ensure the vehicle is parked on a level surface and the ignition is off.
Safety warning: Always engage the parking brake before working on the vehicle.

2. Tire Inspection and Maintenance

Sub-steps:
1. Inspect each tire for damage, such as cuts, bulges, or foreign objects lodged in the tread.
2. Measure the tire pressure using the tire pressure gauge. Inflate or deflate as necessary to match the recommended pressure (typically found on the driver’s door jamb).
3. Check for uneven tire wear that could affect traction. If found, consider rotating or replacing tires.

3. Brake System Inspection

Sub-steps:
1. Visually inspect brake pads for wear. Replace if less than 3mm thick.
2. Check brake fluid level and condition. Replace fluid if it appears dark or contaminated.
3. Test brake sensors and connections using a multimeter to ensure proper functioning.

4. Software Update

Sub-steps:
1. Go to the vehicle’s settings menu on the touchscreen.
2. Select 'Software' and check for available updates.
3. If an update is available, follow the prompts to download and install it.

5. Reset Traction Control System

Sub-steps:
1. Power down the vehicle completely.
2. Wait for at least 5 minutes before restarting the vehicle.
3. Check if the traction control light turns off after restarting.
