⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is secure on jack stands before working on tires.
•Avoid over-inflation of tires; always adhere to manufacturer's specified pressure.

Symptoms

•Tire pressure warning light on the dashboard
•Possible loss of tire pressure in one or more tires
•Uneven tire wear observed during inspection
•Change in vehicle handling or stability
•Low fuel efficiency due to increased rolling resistance

Diagnostic Steps

1
Verify the current tire pressures using a tire pressure gauge.
2
Inspect each tire for visible damage (e.g., punctures, cracks).
3
Check the tire pressure monitoring system (TPMS) for error codes using an OBD-II scanner.
4
Ensure that all tires, including the spare, are inflated to the manufacturer-recommended pressures.
5
Examine the TPMS sensors for proper function and battery condition.

Solution

Solution

1. Preparation

Gather tools: Tire pressure gauge, OBD-II scanner, jack, and tire changing equipment.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Inflate Tires

Remove Valve Caps: Unscrew the valve caps from all tires.
Check Pressure: Use the tire pressure gauge to measure the pressure in each tire.
Inflate Tires: If any tire is below the recommended pressure (found on the driver’s side door jamb), inflate it using an air compressor until it reaches the specified pressure.
Replace Valve Caps: Ensure all valve caps are securely replaced.

3. Inspect and Replace Damaged Tires

Visual Inspection: Examine each tire for punctures or damage.
Repair or Replace: If damage is found, repair the tire using a tire plug kit or replace the tire if necessary.
Recheck Pressure: After repairs, check and inflate to the correct pressure.

4. Reset TPMS

Turn Ignition On: Without starting the engine, turn the ignition key to the ON position.
Reset Procedure: Depending on the model, either use the TPMS reset button (if equipped) or drive the vehicle for a short distance at a speed over 50 mph to trigger the reset.
Check Warning Light: Confirm that the tire pressure warning light turns off after the reset.
