Have a 287c ser# mas00685 right bucket control not working have yellow ! Flashing if I turn left with left stick park lite comes on and stops machine. Have a bunch of codes 444-5 ,91-3 ,2686-8,2685-8,2686-2 ,2685-2 ,2688-8,2687-8,2688-2 , 2687-2,2471-3,2476-3,2476-4,2474-3,2474-4,2475-3,2475-4,358-5,190-8,444-3, please help
Need a bit of basic information first like Serial Number. Is your machine MAS or SSB-prefix.? Next, which of that long list of Codes are Active (Service Mode 1) and which ones are Logged (Service Mode 2).? See attachment. Once that's all figured out we can move forward.
My ser# is at top of thread the codes are from holding down function button and up arrow for 3 sec then pushed down arrow and got these codes
2475-3 and 2477-3 are the codes that has the book open in top left of screen the rest of the many codes was with flopy disk showing
The travel motor speed sensor Codes (268x-x) could be the issue. I can see both LH & RH sensors in your list of Diagnostic Codes Have you inspected any of the electrical wiring on the machine yet.? If not the wiring to both the motor speed sensors would be a good place to start. Also please take a look at that attachment I posted earlier. Get the monitor into Service Mode 6 (Page 4) and take a look through sub-modes 2, 3, 4, & 5. These are for the LH & RH joystick X- and Y-Axis signals. Note the results in the centre and full movement in every direction and post them here please.
So do I go to sub 2 thru 5 and each sub move Joy sticks
And is this all done with key on only or running
yes. Three readings for each sub mode - centre, full one way and full the other. Without the key on your display won’t power up. The engine must be stopped because you don’t want the machine to move when the controls are moved.
Thanks for all the help the first time I went to sub 2 it was 0.0 then I moved the right stick it went thru different numbers that I did not get now it is 100 and does not change
You should see 0 with the lever in the centre, -100 with it all the way in one direction and 100 with it all the way in the other direction. Try all of the other sub modes one at a time and see what results you get.
Ok and 1 more question 2 and 3 for right stick 4 and 5 for left stick ?
Other way around. 2/3 are LH stick, 4/5 are for RH.
Ok will go check thanks
in 2 started 0.0 no change forward nothing back right 100. Left same now all 2 thru 4 is 100 and don't change
And also just found right side in between the track is hoses and a wire bundle and the wires look like they have been pulled on when in mud will check them out in morning and make sure they are making I ng good connection looked like 4 white going into some colored wires thru a connector
Did you ever resolve the right joystick issue? What was the end result?
