I have a 2020 Bobcat T770 that is giving us a couple of intermittent codes. They don’t always come on at the same time but most of the time they do. M4404 aux no communication and also main controller no communication. I can’t remember the code number right off hand with the main controller. When they come on I have no rabbit on the left joystick and the horn won’t blow as well on the same stick and of course no aux power. We have visibly checked all the fuses, relays, connectors, and the harness and don’t see any obvious issues. Does anyone know what might be the cause of this and would the joystick have anything to do with it? Sometimes the aux no com code will come up by itself but the main controller code only comes up after the aux code comes on. Thanks for any help you may have.
