Diagnostic Steps

1
Check the current tire pressures using a tire pressure gauge.
2
Inspect each tire for visible damage, punctures, or foreign objects.
3
Verify if the TPMS (Tire Pressure Monitoring System) sensors are functioning by using a TPMS scanner.
4
Inspect the valve stems for leaks or damage.
5

Solution

1. Preparation

Gather tools: tire pressure gauge, air compressor, TPMS scanner (if needed), and a jack with jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Sub-step 1: Remove valve caps from each tire.
Sub-step 2: Use the tire pressure gauge to measure the pressure in each tire.
Sub-step 3: Compare readings against the manufacturer's recommended tire pressures (found on the driver's side door jamb).
Sub-step 4: If any tire is under-inflated, use an air compressor to inflate it to the correct pressure. If over-inflated, release some air.
Tools Required: Tire pressure gauge, air compressor.

3. Inspect and Repair Tires

Sub-step 1: Visually inspect each tire for cuts, bulges, or punctures.
Sub-step 2: If damage is found, consider repairing the tire (plugging or patching) or replacing it if necessary.
Sub-step 3: Check for uneven wear patterns, which may indicate misalignment or suspension issues.
Tools Required: Jack, jack stands, tire repair kit or replacement tire.

4. Reset TPMS

Sub-step 1: After adjusting tire pressures, locate the TPMS reset button (usually found below the steering column or in the glove compartment).
Sub-step 2: Press and hold the reset button until the TPMS light blinks three times, then release it.
Sub-step 3: Start the vehicle and check if the warning light has turned off.
Tools Required: None.
