Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery (negative terminal) to ensure safety during repairs.
Allow the vehicle to sit for a few minutes to discharge any residual electrical current.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a soft brush.
Check the wiring and connectors for damage; repair or replace as necessary.
Reconnect any loose connections securely.

3. Check and Replace Brake Fluid

Locate the brake fluid reservoir and inspect the fluid level.
If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated or old, perform a brake fluid flush:
1. Remove the reservoir cap.
2. Use a brake bleeder kit to remove old fluid from the system.
3. Fill the reservoir with fresh brake fluid.
4. Bleed each brake line, starting from the farthest wheel to the nearest.

4. Update Software

Connect the vehicle to Wi-Fi and check for software updates via the Tesla interface.
If an update is available, follow the prompts to install it, as this can resolve electronic control system issues.

5. Tire Inspection and Replacement

Check tire pressure with a tire pressure gauge and inflate to the manufacturer’s specifications.
Inspect tires for uneven wear; replace tires if necessary to maintain proper traction.
