Solution

1. Preparation

Tools Required: Tesla diagnostic tool, torque wrench, tire pressure gauge
Safety Warnings: Ensure the vehicle is in park and turned off before starting work.

2. Update Software

Connect the vehicle to Wi-Fi.
Navigate to 'Software' in the vehicle settings.
Check for available updates and install them if necessary.

3. Inspect and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as per Tesla specifications).
Ensure the cap is securely closed after adding fluid.

4. Check Wheel Speed Sensors

Lift the vehicle securely using a jack and jack stands.
Inspect each wheel speed sensor for damage, dirt, or disconnection.
Clean any dirt or debris around the sensors and reconnect any loose connections.

5. Verify ABS Functionality

With the vehicle in a safe area, perform a brake test to activate the ABS system.
Listen for the activation of the ABS pump and check for any unusual sounds.
If the ABS system does not activate correctly, further diagnostics may be needed.

6. Tire Inspection

Check all tires for proper inflation using a tire pressure gauge.
Ensure all tires are of the same size and tread pattern.
Replace any damaged or uneven tires to maintain traction.
