⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface while checking or inflating tires.
•Use caution when handling tire changing tools to avoid injury.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible under-inflation of one or more tires
•Uneven tire wear observed
•Tire pressure may be lower than the recommended PSI
•Potential handling issues (e.g., pulling to one side)

Diagnostic Steps

1
Check tire pressure with a reliable tire pressure gauge.
2
Inspect all tires for visible damage or punctures.
3
Reset the tire pressure monitoring system (TPMS) according to the owner's manual.
4
Scan for error codes using an OBD-II scanner to check for TPMS-related faults.
5
Verify the battery condition of the TPMS sensors if applicable.
6
Check the tire valve stems for leaks or damage.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and turn off the ignition.
Ensure all tires are cool for an accurate pressure reading.

2. Check and Adjust Tire Pressure

Tools Required: Tire pressure gauge, air compressor
Instructions:
1. Remove the valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Compare the readings to the manufacturer's recommended PSI (usually found on the driver’s side door jamb).
4. If any tire is below the recommended pressure, inflate it using an air compressor until it reaches the correct level.

3. Inspect Tires for Damage

Tools Required: Visual inspection (no special tools needed)
Instructions:
1. Examine each tire for visible cuts, punctures, or bulges.
2. Look for uneven wear patterns which may indicate alignment or pressure issues.
3. If any damage is found, consider replacing the affected tire.

4. Reset TPMS

Tools Required: None (manual reset)
Instructions:
1. Turn the ignition to the "ON" position without starting the engine.
2. Locate the TPMS reset button (usually under the steering column).
3. Press and hold the reset button until the tire pressure light blinks three times, then release it.
4. Drive the vehicle for a short distance to allow the system to recalibrate.

5. Replace TPMS Sensors if Necessary

Tools Required: Tire changing tools, TPMS sensor tool
Instructions:
1. If the tire pressure light remains on after checking pressure and resetting, the TPMS sensors may need replacement.
2. Remove the tire from the wheel rim using tire changing tools.
3. Replace the old TPMS sensor with a new one, ensuring it is properly seated.
4. Reinstall the tire and check for proper seating and inflation.
