Hey guys I'm looking for some guidance. My 2016 T770 has been throwing error code M4404 (aux no communication) for a month or so. The machine has never missed a beat. Until the today. Thru the code an my aux switch went dead. Zero movement in the grapple. Also the aux/high flow button seems non responsive. The aux light is lite, but I can not switch to high flow or off.
From my research today I found a few people with the same problem. And the Aux Controller Module seemed to be the fix for them. It was either a bad connection or just a bad module.
Where do I find the aux controller module? An has anyone else dealt with this or a similar problem?
TIA!
