Right SJC doesn't work S750

[TB]

Not too long ago I had the right joystick start to throw a code. Now we're up to>>> bobcat s750 codes h4016 w3276 d7501
I can switch from H to ISO pattern to move the machine around but the right stick doesnt perform correctly. Are there any known values across wires to help with diagnosis? I'm not into just swapping parts. cleaned ground terminals at battery, checked fuses, need to lift cab next and see if any pinch points caused issues but would sure like to be able to test components or wire loom at some known point to verify issue before throwing money at it. Anyone else have this issue that can recommend point(s) to check?

Thanks for the offer.. in the event it is the joystick, what would cost be to repair it and ship it back?

Is there a way to isolate whether the issue is from the joystick or controller? If I switch from ISO to H or the other way around, the issue remains with the right hand. I can sometimes go very very slowly and get the control to function, (right wheels forward/reverse in H for example) but move quickly and it triggers an error. I can then shift to ISO, use the left joystick to drive, but if I have to move bucket up/down, it triggers error again. and so on.. help or direction appreciated
