| The skid steer wont unlock the controls to allow you to use the bucket. The park brake and seatbelts light flash and the light next to the button you push to unlock the hydraulics flashes. Any idea where to start.the machine starts and moves just no bucket controls.

Seat belt switch or seat switch..
Seat belt switch. If the board lights up when you sit, the seat switch works. |

NE Iowa | I've had to replace the seat switch in mine twice already. It acts like that when it goes. You can disconnect the seat sensor and take a little 3" piece of wire and loop it between the 2 terminals and get by today until you get a new sensor tomorrow. |

Wi | How does it act in service mode?
Seat belt switches go bad enough as do seat switches, safety interlock and the boards themselves. Then there's the occasional rubbed wire.
I'm not at the shop but do have a service manual for them with the wiring diagram and specs if you want to avoid swapping parts and would prefer to test them instead |

| Not sure what its suppose to do or how its suppose to act in service mode. I jumped the seat switch and that didnt seem to have any affect. Cant seem to find the seat belt switch but with the seat belt unbuckled it dosent start with it buckled it starts. It shows there is suppose to be a fuse for the bucket in the fuse panel in the cab but there isnt even a so I for a fuse there. |

Service mode just allows you to start the machine by overriding the interlock. It will not allow you to run the hydraulics. Check the position of this switch because even if everything is working properly, if you accidentally bump the switch to service it will not allow the boom/bucket to unlock. The switch must be in run for them to work.
If it starts, then the seat and seatbelt switch are both fine providing the switch is in the run position and not service position, its possible its in service position and your seat belt switch is bad but due to being in the service position its allowing the machine to start. It shouldn't start with either of those not working normally. The seat belt switch is inside the buckle, somebody found one at radioshack that you can fix it with, otherwise you can buy the entire assembly (they dont sell any of it seperate). If the board is lighting up when you sit down, the seat switch is working. If the seat belt light is not going out when you fasten the seat belt, there is likely something wrong with it. If it is going out then your issue is somewhere else. The seat belt switch gets power from the seat switch then sends it to the interlock and EIC.
Make sure the EIC (Electronic Instrument Cluster) is getting power from the seat belt switch (Light green wire, pin 11 of connector 2). Make sure the EIC is sending power out to the lock solenoids. You can test the lock solenoids by removing the cover between your feet. Sit down in seat with key on and buckle seat belt. Service switch in run. Unplug them and test for voltage, black wire is ground purple/blue is voltage. If no voltage, check against a good frame ground. If that works, repair the ground. If theres still no voltage yet the EIC is sending voltage, you have found your issue, start following the wires.
If there is voltage and its not unlocking you can check the solenoids, they should read 15-18ohm's.
Remove the fenders so you can follow the wiring harness. I do rememeber having an issue with one on one of the sides because the hoses rubbed through the wiring harness.
I just noticed you have an unlock button meaning you have a later one with a different EIC. We had a later one as well and most of it is wired very similar but there may be some differences on your machine.

|
| Is there any way to make sure EIC is sending power out. I have voltage on the green wire but no voltage at solenoid |
|
| |
|
Wi | Yes, it should be sending voltage out to the solenoid. Pull the EIC out and see if you can figure out which wire is going to the solenoids. I don't know which one is should be specifically and your display is probably different anyways.
You can unplug both and use you DMM to find which wire is running from solenoids to EIC then see if EIC is putting voltage onto that line. If you can't find a wire make sure the wire going away from solenoids isn't shorted to ground. If you still can find it you may need to start pulling more stuff apart to trace it. If the EIC is sending voltage the wire is your issue. If the EIC is not sending any voltage but it's receiving voltage from seat belt then it's likely a fried EIC. Don't know how the newer ones are, older ones failed a lot but did not have the unlock button.
The only other thing is the service/run switch did you check it's position? I'd have to look back at how it interrupts the lock solenoids when it is in service mode. A bad run/service switch could possibly be your issue as well.
Just to be sure, you did check all of the fuses correct? Regardless of what they say they are for? There aren't a lot of them, just the few up top on right in cab which is where service switch is at and the two banks in the engine compartment behind cover with wingnut.
Just read the original post again, are you sure the service/run position switch is in the "run" position? What you're describing is exactly how it's supposed to act with it in service position. The lights are supposed to flash like that even if the sensors are working. If you are getting power to the EIC from the seat sensors then they are good. The service/run in service will not allow controls to be unlocked even if you have seat belt fastened. Try the switch in both directions to see if it makes a difference. |

northeast SD | My LS180 gave me fits with that same issue. After two weeks in the shop and three service calls later, a new board fixed it. |

Wi | The easiest thing to do IMO is try starting the machine without buckling seat belt. If it starts, service/run is in service. Flip the switch the other way and try to start it. If it starts then something is wrong with switch or wiring causing machine to be in service mode. If it doesn't start, service/run is likely working properly and thus the issue is further down the line.
With the older display you could run a diagnostics test through the display to see if everything was working right but I know the newer ones had far less features.
Attached is the wiring for the service/run switch on the earlier LS machines.

When everything else is fine, its time for a new board, they were not an uncommon failure. However many people test all of the components, then replace the board only to not find an issue because it was a wiring issue all along. |

| I've tried the service switch in both positions. Still cant get power to the solenoid. I checked all fuses twice with a test light. The only thing I cant figure out is wether there is suppose to be another fuse in the panel in the cab. It shows a 5amp with a bucked and lock next to it but there is only a 7.5 on that side when the diagram shows two a 7.5 and a 5. I feel like it should be something simple as it was working fine and got out and got back in and it wouldn't work. But iv double checked everything that I can see. It starts runs and moves and wont start when the seatbelt isnt buckled or your not in the seat. Seems both switches are working properly. All fuses check out. Maybe a faulty EIC but no way to really check that. Cant even think of another skid steer in the area to swap one with just to try. |

Wi | Bucket lock fuse is likely for the hydraulic locking plate which you must not have hence no fuse. Those were another set of headaches lol. If you ever get one, rip the solenoids off the plate and mount them inside the right fender under cab. Rewire and replumb the hydraulics to allow this and you'll be good. Out front those things cause all kinds of headaches especially in manure.
Go Bruce the machine around a lot. If everything is testing good it points more towards a bad EIC or wire. What does the back of the EIC look like?
I would at least follow the harness to see if you can see anything obvious. Jump in the seat and use a jumper to send power to the solenoid so you can unlock boom and get it in the air. Rule #1 of owning a new Holland, don't break down without boom in the air lol. Then raise seat and Remove fenders so you can follow the harness to look for any obvious abrasions.
I don't miss fixing all of our LS170s (still have one with a 10,000hrs though) but I do miss how simple they were to work on and diagnose. Especially electrically. |

ok | Check your battery ground really closely. I had one doing similar things and finally I traced it down to a bad ground cable. Replaced and everything works as it should now. |

Positive too. Both cables give issues, positive is very common we couldn't get two years out of them for some reason. |
