Tools Required: None
Safety Warnings: Ensure the vehicle is parked safely while updating.

2. Inspect Wheel Speed Sensors

Sub-steps:
- Raise the vehicle on a jack and secure it with jack stands.
- Locate the wheel speed sensors on each wheel hub.
- Inspect the wiring and connectors for any damage or disconnection.
- Clean the sensor area with a soft cloth if dirt is present.

Safety Warnings: Ensure the vehicle is securely raised and stable before working underneath.

3. Check Brake Fluid Level

Sub-steps:
- Open the front trunk (frunk) and locate the brake fluid reservoir.
- Check the fluid level against the minimum and maximum markers on the reservoir.
- If low, add the recommended brake fluid type as specified in the owner's manual.
Tools Required: Brake fluid (DOT 3 or DOT 4, as specified)
Safety Warnings: Avoid skin contact with brake fluid; it can damage paint.

4. Tire Inspection

Sub-steps:
- Inspect all tires for uneven wear, damage, or low tread depth.
- Use a tire pressure gauge to check each tire's pressure and inflate to the recommended PSI.
- Replace tires if the tread depth is below the minimum requirement.
Tools Required: Tire pressure gauge, air compressor, possibly a tire tread depth gauge
Safety Warnings: Ensure the vehicle is on a flat surface while checking tires.

5. Test ABS Functionality

Sub-steps:
- Perform a test drive in a safe, controlled environment.
- Engage the brakes firmly at a low speed to see if the ABS activates (you should feel a pulsing in the brake pedal).
- If the ABS does not engage, further inspection may be needed.
Tools Required: None
Safety Warnings: Always conduct test drives in safe areas away from traffic.
