Suspension

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure that the vehicle is parked safely and the engine is turned off before performing any tire work.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible tire pressure readings showing low or high values on the display
•Uneven tire wear visible on the tread
•Handling issues such as pulling to one side or vibrations during driving
•Reduced fuel efficiency or range indicated on the display

Diagnostic Steps

1
Check the tire pressure using a digital tire pressure gauge for all four tires.
2
Compare the measured tire pressures to the recommended levels found on the driver's side door jamb sticker.
3
Inspect the tires visually for any signs of damage or punctures.
4
Verify that the tire pressure monitoring system (TPMS) sensors are functioning correctly by checking for error codes using the vehicle's diagnostic screen.
5
Reset the TPMS system if the tire pressures have been corrected.

Solution

Solution

1. Preparation

Gather necessary tools: digital tire pressure gauge, air compressor, TPMS reset tool (if needed).
Ensure the vehicle is parked on a level surface and the tires are cold for accurate readings.

2. Check Tire Pressures

Sub-steps:
1. Remove the valve cap from each tire.
2. Use the digital tire pressure gauge to measure the pressure of each tire.
3. Record the pressure readings and compare them to the recommended values.

3. Inflate or Deflate Tires

Sub-steps:
1. If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
  - Ensure to check the pressure again after inflating.
2. If any tire is over the recommended pressure, release some air until the correct level is reached.
3. Replace the valve caps securely on each tire.

4. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. If the tire pressures are correct but the warning light remains, inspect the TPMS sensors for damage.
2. If faulty, remove the tire from the wheel using a tire changing machine.
3. Replace the TPMS sensor with a new one, ensuring it is compatible with the Tesla system.
4. Reinstall the tire and balance it properly.

5. Reset TPMS

Sub-steps:
1. Access the vehicle's settings through the touchscreen.
2. Navigate to the tire pressure monitoring system menu.
3. Select the option to reset the TPMS.
4. Confirm the reset and monitor the dashboard for the warning light.

Tools Required:
