VCSEC_a221: Air pressure below recommendation for tires

Symptoms

["Add air to maintain the recommended cold tire pressure. Although drops in tire pressure are expected in colder weather, the recommended cold tire pressure should be maintained at all times.", "The alert may clear as the vehicle is driven. This is because the tires will warm up and the tire pressure will increase. Even if the alert clears, the tires should still be refilled with air once they have cooled.", "The alert will clear once the Tire Pressure Monitoring System detects that each of your tires is inflated to the recommended cold pressure."]
