Hey guys. New to the forum. I have a M923a2. We put 1600's on it. System worked fine, but one tire has a slow leak. I didn't drive the truck for a few weeks and the tire got pretty low (didn't check pressure). It would attempt to air it up for a few min, then I would get flashing lights. I read in this thread to press emer and run flat at the same time and it would pressure the tires down to the same pressure, then inflate them back up to whatever setting I choose. All the tires deflated, but now the system attempts to air them up, but fails to do so. I'll get a steady light on the emer and the mode I select. Anyone have an idea what is going on? Thanks in advance.
