Is there a way to tell if the differential lock is engaged when the switch is engaged. The light on mine does not illunimate so I do not know if the differential is locked and the light burned out or if the whole system is not functioning. I am in two wheel steer with front and rear pointing straight. No error codes show.

Thanks for the help.

On two of my TC's the iluminated swith (for diff lock) in the center dash behind the joystick came loose and would no longer iluminate. You might try pulling off the palm/arm rest, remove the two bolts, then pull the rubber cup holder liner and remove the torx screw which will allow you to pull the entire plastic center out and check to see if the wiring plug to the switch has come loose.

Thanks for the help. I checked the connection and it is fine. I reconnected to ensure it is firmly seated.

Interesting find though, I can lock the differentials if I am at idle and in park. Will remain locked when forward is selected and throttle is increased. If I release the differential lock it will not reengage unless I lower the throttle and place in park.

Any idea what safety sensor may not be functioing?
