When a tire has low air pressure, it can cause the wheel to be out of balance, which can lead to vibrations and other issues. The wheel balancer will detect this imbalance and display the "lpg lo" code to alert the technician that the air pressure needs to be adjusted.
It's important to address low tire pressure as soon as possible, as it can not only affect the balance of the wheel but also compromise the safety and performance of the vehicle. The recommended tire pressure for a specific vehicle can usually be found in the owner's manual or on the sidewall of the tire itself.
