i'm working on a bobcat t550 and i'm getting a D7501 code. this is a communications error code and it is linked to the can bus so i started with the basics checking the wiring and i cant find any bad wiring. i then swapped out the left joystick with another t550 that is working fine because i got the H3928 code and that is a internal can failure. and it still wont fix the issue. the unit will move 10 feet and then stop like if you lifted the safety bar then you can press the operate green button and move again and it locks out again. i also swapped out the switch on the safety bar as well and that did nothing.
so here i am reaching out for some help has any one else had this problem?????
