⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked on a flat surface and the engine is off before performing any checks.
•Avoid over-inflating tires; follow the manufacturer’s specifications closely.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Potential loss of handling or stability
•Uneven tire wear observed
•Decreased fuel efficiency
•Unusual noises while driving (if tire is significantly under-inflated)

Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect the tires visually for signs of damage, punctures, or wear.
3
Verify if the TPMS is functioning by using an OBD-II scanner to check for error codes related to the tire pressure monitoring system.
4
Examine the valve stems for leaks or damage.
5
Reset the TPMS system after inflating the tires to the recommended pressure.

Solution

Solution

1. Preparation

Gather necessary tools including a tire pressure gauge, an air compressor, and an OBD-II scanner.
Ensure the vehicle is parked on a flat, stable surface and the engine is off.

2. Check and Inflate Tires

Sub-steps:
1. Remove valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Compare the readings with the recommended tire pressure (usually found on the driver’s side door jamb).
4. If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
5. Replace valve caps securely after inflation.

3. Inspect Tires for Damage

Sub-steps:
1. Look for visible punctures, cuts, or bulges on the tire sidewalls and treads.
2. Check for uneven wear patterns, which may indicate alignment or suspension issues.
3. If damage is detected, replace the tire as necessary.

4. Reset TPMS

Sub-steps:
1. Turn on the vehicle without starting the engine.
2. Navigate to the 'Service' menu on the touchscreen display.
3. Select 'Tire Pressure Monitor' and choose 'Reset'.
4. Confirm the reset and wait for the system to recalibrate.
