⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely parked and the engine is off before working on tires.
•Use caution when handling tires and maintaining proper pressure to avoid injury.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible decrease in vehicle handling performance
•Increased road noise or vibration during driving
•Flat or visually low tire(s)
•Inconsistent tire pressure readings on the vehicle's display

Diagnostic Steps

1
Inspect each tire visually for signs of damage, punctures, or low pressure.
2
Use a tire pressure gauge to measure the air pressure in each tire.
3
Check for any stored error codes using the Tesla's diagnostic system.
4
Ensure that the tire pressure monitoring system (TPMS) sensors are functioning properly.
5
Verify if there has been a recent temperature change that could affect tire pressure.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

Diagnostic Steps

1
Inspect each tire visually for signs of damage, punctures, or low pressure.
2
Use a tire pressure gauge to measure the air pressure in each tire.
3
Check for any stored error codes using the Tesla's diagnostic system.
4
Ensure that the tire pressure monitoring system (TPMS) sensors are functioning properly.
5
Verify if there has been a recent temperature change that could affect tire pressure.

Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, TPMS tool (if necessary)
Ensure the vehicle is parked on a level surface and the tires are cool.
Gather necessary tools and parts.

2. Check Tire Pressure

Sub-steps:
1. Remove the valve stem caps from all tires.
2. Use the tire pressure gauge to check the pressure of each tire.
3. Compare the measured pressure against the manufacturer's recommended pressure (typically found on the driver's door jamb).

3. Inflate or Deflate Tires

Sub-steps:
1. If the tire pressure is low, use an air compressor to inflate the tire to the recommended pressure.
2. If the tire pressure is high, press the valve stem to release some air until the correct pressure is reached.
3. Recheck the pressure after inflating or deflating.

4. Reset the TPMS

Sub-steps:
1. Turn on the vehicle and access the settings menu on the touchscreen.
2. Navigate to the "Service" or "Tire Pressure" section.
3. Select the option to reset or calibrate the tire pressure monitoring system.

5. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. If the warning light persists after pressure adjustments, inspect the TPMS sensors for damage or malfunction.
2. If needed, remove the wheel, and replace faulty TPMS sensors according to the manufacturer's specifications.
3. Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.
