⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is on a stable surface when lifting with a jack.
•Wear safety glasses when working with pressurized air.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible noticeable drop in tire pressure
•Uneven wear on tire treads
•Vehicle pulling to one side while driving
•Decreased fuel efficiency

Diagnostic Steps

1
Visually inspect all tires for any visible damage, punctures, or signs of low inflation.
2
Use a tire pressure gauge to check the pressure of each tire against the manufacturer's recommended levels.
3
Check the TPMS sensor status; if equipped, use an OBD-II scanner to check for any stored error codes related to the TPMS.
4
Inspect the TPMS sensors for proper installation and functionality, especially if the tires were recently changed or rotated.
5
Reset the TPMS system according to the vehicle's owner manual after addressing any tire pressure issues.

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, OBD-II scanner (if needed), and a jack.
Park the vehicle on a level surface and ensure the engine is off.

2. Tire Pressure Adjustment

Sub-step 1: Remove the valve cap from each tire.
Sub-step 2: Use the tire pressure gauge to measure the tire pressure.
Sub-step 3: If the pressure is below the recommended level (check the sticker inside the driver's door), add air using the air compressor until it reaches the recommended pressure.
Sub-step 4: Recheck the pressure to ensure it is accurate.
Sub-step 5: Replace the valve caps securely.

3. TPMS Sensor Check

Sub-step 1: If the pressure is correct and the light remains illuminated, check the TPMS sensors.
Sub-step 2: If using an OBD-II scanner, connect it to the vehicle's diagnostic port and scan for TPMS-related error codes.
Sub-step 3: Address any issues indicated by the error codes, which may involve replacing faulty sensors or wiring.

4. Resetting the TPMS

Sub-step 1: Follow the manufacturer's instructions to reset the TPMS (usually involves turning the ignition on/off or using a dedicated reset button).
Sub-step 2: Drive the vehicle a short distance (15-30 minutes) to allow the system to recalibrate and verify that the warning light turns off.
