CNH Electristeer fault

[Daniel]

Have you tried going into the settings and just turning off Glonass as a test when it has the issue?

Doesn’t Glonass add extra satellites?

 

[Wombat]

Yes but just might help to isolate the issue. If it still shows 6/7 then the drop is in the Glonass sats. How long is the distance to base you are using. I assume the screen shows it somewhere

Ah! I’ll try that thanks.

It’s ntrip, it used to say about 28kms from base but now it seems to set up a new base station point each time you start the tractor?

I’ve got the Case version on my sprayer, been fine up until Sunday, used Friday with no problems, Sunday it didn’t want to know. Comes up with a fault warning saying can’t engage and if problem doesn’t clear reset system.
I’ve not reset it yet as I’d rather not lose all settings, I’ve done some test calibrations today and it operates left and right itself but ask it to engage on a A-B line and the fault reappears, it does this on RTK and egnos so I’m not suspecting signal, also the tractors all work fine on our RTK mast at the moment. I don’t hold out much hope that my dealer will know. Any thoughts appreciated.

I've been having a nightmare with my sprayer.
New screen fitted, wouldn't start up properly.
4 months later it's diagnosed to the steering wheel motor interrupting the can messages on startup.
New motor £3100!!
Since discovered if I isolate the steering motor with the emergency kill switch it all starts up fine, and once running I can let the motor be seen by deisolating it, all works perfectly.
4 bloody months of nearly setting fire to the damn thing.
Could have happily murdered it.

My motors a little different to yours, it’s a wrap around motor not a replacement wheel but I’ll give it a try, by emergency kill, is that just turning it off as my motor has it’s own on/off switch, never needed to touch it before, just leave it on.

 

[Pheasant Surprise]

I had it on the drill today, 11-13 satellites all day, sure enough at about 5pm, satellite numbers drop down to 8-9, and the RTK drops out constantly. How do you stop it doing this?

Let me know if you want to test using my base. I can set you up an NTRIP login. Then see if the problem persists.

When they fitted it, they put a red isolator switch on the line to the wheel motor.
Safety reasons.
Try turning it off, see if it starts up OK, then turn it on.

 

[Badshot]

Should say I have to isolate before starting the screen or it doesn't work.
Once the screen is up and running then turn the wheel on.

 

[MrNoo]

Ha, found the issue on mine!!! My mobile phone had the "hotspot" icon clicked as I use it for t'internet connection at homw as it's speedier than my steam driven t'internet. Turned that off and my Trimble 750 logged straight in no issue at all, guess the modem was trying to log onto my phone.
To be doubly sure I turned it on again on the phone and the 750 wouldnt log in at all, so that was the reason why mine wasnt working yesterday.

 

[Matt77]

Tried starting it with motor off and then turning on once screen set, no joy.
Put the receiver on the tractor and that works fine, I’ve got as far as loading the settings on to a USB, took well over an hour and have reset it, now it needs settings loading back up, when I’ve a spare hour or two!

 

[Matt77]

So it’s looking like the pro 700 screen might be the problem, went to get it updated but it’s already running v31.6 so we left it, the ecu can see the receiver, I can log onto it via a tablet, it’s showing speed and RTK age, the sprayer screen can see the receiver and functions properly, the pro 700 can’t see the receiver, well it can but it’s not working, showing 98% on the RDI screen and 18 or so satellites but non tracked, the GPS page doesn’t show anything on coordinates etc, the speed (or lack of) is showing “speed (wheel)” and when it was working it said “speed (gps)” I’ve reset more times than I care to do and no improvement, I don’t have a functioning laptop these days but will try and borrow one and connect to the ecu via the Ethernet cable, just in case that’s any better, after that I’m out of ideas.

Have you an old version of firmware?
My Puma worked on a 4 year old version, put the latest on and nothing, didn't recognise it.
That was due to a bit of heath Robinson wiring.
Worth a go maybe.

I don’t have anything, Andy was going to update it last night but said v31.6 was more recent than my tractor screen, which is working fine, so he felt it would be a mistake to change it, he’s off next week too so it’ll have to wait if I try any dealer update. I still think there’s too much of a coincidence that it stopped working after the date that this so called satellite roll over happened?? Yet both tractors are fine

 

[Badshot]

Sent you a link on what's app

Most gps in this area is cutting on and off this week last few nights satellites drop down around 6 o'clock then come back later. Can't map fields with my topcon system as it says date and time not recognised Supposed to be back to normal next week if not system update is required

Your not the first to report that @Daniel. Also with Topcon based receivers, in his case AgroSky

What other symptoms are you seeing? Have you made sure the system is running the latest firmware and isn’t affected by the GPS week date rollover issue that affects receivers since 6/7 April?

Not checked firmware just assumed its to do with the date rollover and would hopefully be back to normal next week not using it much last few days but last two nights lost steering about 6 o'clock when satilites dropped to 6 but within an hour was back to normal but still couldn't map fields Had a friend have problems with his trimble today no steering and map lines jumping about

If it is a date rollover issue, then unfortunately no it will require a software update to resolve the issue as it won’t get better or go back to the way it was...

In effect the GPS network “week” which is broadcast has rolled over from 1023 back to 0, therefore without the software patch your receiver may think it’s in 1999.

 

[Badshot]

Why does it matter if the screen thinks its 1999?

 

[Pheasant Surprise]

Why does it matter if the screen thinks its 1999?

Quite important for accurate system time, not just for reporting accurate time, but to do with position information and its calculation as I understand it.

For example it may cause the receiver issues with interpretation of the GPS satellite almanac which the receiver downloads, telling it where to expect to “see” the birdies and which ones are healthy or out of service.

Very accurate system time is also needed to calculate absolute position, so the actual calculated position may be significantly out. It may cause issues with correction services for the same reasons.
