I have a 2012 john deer 318d. Recently I started blowing the fuse on the lab bar sensor circuit. So I replaced the lab bar sensor checkd the wiring for a short and replaced the parking brake sensor for good measure. Now when I start the machine, cycle the lab bar and cycle the parking break both indicator lights go off as if it's ready to operate however the foot pedal locks don't release. Oddly enough, my wheel locks started not locking a little while back and still dont. I also have a hydraulic fluid temperature light that turns on at initial start and doesn't seem to go off. I don't see how that could be related. But hey things are complex these days. I replaced my oil filter then the indicator light started.
