I've had this issue since late last year. I've taken it to two different shops. The last being the closest Bobcat shop. After spending months and thousands they still have not fixed this issue. The same issue it went in for. You turn on the skid steer, no problem. Then after you release the parking to operate, it shuts off completely. I've attached a list of items that they have looked into. But, after getting new sensors, swash plates, bushings, cleaning out the fuel tank etc., they have not been able to identify the cause. And throwing money at it is not what we want to keep doing. It's so frustrating. Some things not included on the attachments from the first shop. But, I thought if anyone would know it would be the actual Bobcat shop. But nope. We are now looking into the Cab wiring harness. Any ideas?
Wow thats a hefty amount of work and and one expensive car wash. Sounds like they cleaned it up good for you. Are these places bobcat dealers or just shops that work on whatever rolls in ? The electrical system, gateway, etc can all be tested with software. Everything they listed like swash plate sensors , charge pressure would all trigger a DTC. Odd they rebuilt it but say nothing of the test readings. They BICS system and bobcat controllers really work separate from engine ecm. They pull select information from ecm but turning off parking brake and machine shuts off is not on that wave length. Does it die soon as you turn off switch ? Motor just shuts off? No lag no loading up nothing but brake switch off and it just turns off same as shutting off key ?? Does it restart right after and it stays running as long as you don't release parking brake ?? No codes no nothing ? Only real common point between the two is the harness. But even a bad harness would feed to the gateway and controll group controller. The gateway then interfaces with the engine ecm to send/receive data. You could possibly have an issue on the OE supply side but again I would suspect you would get a DTC. No fuses blow no nothing ? I have replaced tons of can harness over the years but not one caused a machine to die like yours. When it dies does the display stay On? Once it dies can you turn the key and try to restart it? They key switch stays on its not dead no power ?? Does it do it if you try it in override ?? Do you know if the remote start tool yielded the same issue??? Sorry a lot of questions but this is one where the more information the better. Your going to need someone like a bobcat dealer with dealer level software to handle it. You need to see the data to truly understand whats going on. You need to be able to access the controllers etc. To get to the bottom of it. Cab harness maybe maybe maybe maybe. But I would say any electrical issue that bad would have gone down in smoke and that good burning plastic smell already
