Solution

1. Preparation

Gather tools: tire pressure gauge, Tesla diagnostic tool, and a socket set.
Ensure the vehicle is parked on a level surface and the tires are cool before proceeding.

2. Inspect and Replace TPMS Sensors

Sub-step 1: Remove the tire from the vehicle using a jack and jack stands.
- Tools required: jack, jack stands, and lug wrench.
Sub-step 2: Remove the tire from the rim to access the TPMS sensor.
- Tools required: tire lever and bead breaker.
Sub-step 3: Inspect the TPMS sensor for damage or corrosion.
Sub-step 4: If damaged, replace the TPMS sensor with a compatible new sensor.
- Torque the sensor nut to the manufacturer’s specified torque (usually around 3-5 ft-lbs).

3. Reinstall Tire

Sub-step 1: Reinstall the tire onto the rim and ensure it is properly seated.
Sub-step 2: Inflate the tire to the recommended pressure stated on the door jamb sticker.
Sub-step 3: Reinstall the tire onto the vehicle and tighten the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

4. Reset TPMS

Navigate to the vehicle's settings menu and select the option to reset the TPMS.
Follow on-screen prompts to complete the reset.
