As a result, an air leak may occur, causing the warning light to illuminate. If use continues, the air pressure will drop, leading to emergency braking…
Component	Braking system (air dryer regeneration control valve)
Remedy	For all vehicles, replace the air dryer regeneration control valve with an improved part and rewrite the control program to prevent moisture in the compressed air from freezing when the outside temperature is low. Additionally, designate the air dryer regeneration control valve as a regularly replaced part and affix a sticker to the maintenance note indicating the added regular replacement period (1 year).
