I kicked on my CTIS to make up for the typical 3 psi per day loss in the rear tires. After about 3 minutes the rear tire pressures had dropped about 10 psi and was continuing to drop. The CTIS compressor was running, but there was a fair amount of air coming out of the dust excluder on the CTIS manifold.

I'm assuming the dust excluder blew out? Anyone have any experience on this?

And, as a side note, does anyone know a reliable H1 mechanic located in the Southeast Tennessee area?


Thanks

 

I took apart my middle valve apart cleaned and and worked, inside gets debris and shoot out more air then takes in to fill

 

Stuck deflate valve. It's the middle valve on the CTIS manifold. Sometimes you can tap on it and it will spring back, but most of the time you'll have to isolate your CTIS system, then open up the valve and clean it out. It is pretty easy to do yourself and should only take about 30 mins. Doing it yourself will save a lot of money since CTIS repairs are expensive. I know places here in Michigan will charge over $200 just to clean the deflate valve.
