Gentlemen, my 91 M925 CTIS seems to be cycling but not actually filling tires. Upon starting the truck, the system builds up pressure on both gauges but once it reaches operating pressure the system seems to keep recycling. A relief valve or something under the dash seems to bleed off a quick burst of air every 10 seconds or so.
Also, I had a very slow leak on a rear tire at the valve which I repaired. I figured that starting the truck would get the CTIS to fill the now empty tire. The CTIS system had no effect on the flat. I had to fill the tire manually.
The CTIS on my H1 works much differently. It will fill tires from flat and is not "computer" controlled.
Any help on this would be appreciated. I know many just unplug the system but I like everything to work and work correctly.
