Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to avoid any electrical shorts during the repair.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel covers (if applicable) and tires to access the wheel speed sensors.
Inspect each sensor for dirt, damage, or corrosion.
Clean each sensor with a soft cloth and appropriate cleaner; do not use abrasive materials that could scratch sensors.
Reassemble tires and wheel covers.

3. Check and Replace Brake Fluid

Locate the brake fluid reservoir.
Check the fluid level; if low, top off with manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4).
Inspect for any visible leaks around brake lines and connections.
If leaks are found, replace affected components as necessary.

4. Test and Update Software

Reconnect the battery and power on the vehicle.
Connect the vehicle to a Tesla service computer or use the Tesla Mobile app to check for software updates.
If an update is available, follow on-screen instructions to install it.

5. Inspect and Adjust Tire Pressure

Check the tire pressure using a tire pressure gauge.
Inflate tires to the recommended pressure listed on the driver's door jamb or in the owner’s manual.
Inspect tires for uneven wear or damage, replacing any tires that do not meet safety standards.
