CNH Electristeer fault

[Matt77]

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 think it may be because of change of satellites

I would happily take a club hammer to the GPS in our Deutz, Case system not much better, riddled with bugs and no one at the dealerships have a clue about them.

One is Trimble underneath one is Topcon, neither were properly developed or tested, Deutz one doesn’t seem to see enough satellites after about 5pm to stay connected. And for today’s party trick lost it’s wheel sensor and mounting bias calibrations.

I can’t recalibrate it because it won’t hold onto its rtk farming correction signal as it’s downed tools at 5pm like some unionised factory worker.

Anyway it’s made me go home and play games with my daughter instead so there’s something to be said for it.

I did wonder this but the tractors on the same mast/network work today?? But if this is the case what should I do about it, do you know? On the RDI screen it’s showing 98% which I always thought was how strong the signal was. I drive the section control out of port B into the sprayer screen and that’s all still working, well it seems to be, but steering just won’t.

No experience of it yet, was just told by new Holland dealers that last weekend the satellite systems were changing

So frustrating but I can see my wheelings so not holding me up so to speak. Never a bad thing if it allows family time though

I’ll make a call tomorrow then, see what they have to say for themselves

When were they changed do you know??? Zero RTK today when wanting to spread fert, had to do it on manual shut off/on, tried it on Egnos but wouldnt have that. Phoned my dealer and the GPS bod is on holiday............!!
So far I have lost 2 days spreading, one with a faulty actuator (buggered after spreading 1750 ha worth or 48hrs spreading) and RTK issues today. I do question the merits of some of this stuff at times.

 

[goodevans]

Last weekend I believe

 

[MrNoo]

Last weekend I believe

The one just gone ? 6th 7th April or the one before?

 

[goodevans]

Like I said I have no experience yet as only just moved into this territory but I think it was this weekend just gone,as yet it is all double Dutch to me

 

[Slick]

It was the 6th/7th April, in very simple terms (I'm very simple) the gps 'clock' resets itself to zero every 1024 weeks which was last weekend.

Things to check on diagnostics (very much in general, not colour or auto-steer type specific)...

1. How many satellites are acquired? You need sufficient satellites in clear view, with good geometry, satisfying minimum system HDOP.

2. Correction signal/service is present and converged. No dropouts, pauses or delays.

3. Gyro, wheel angle and steering angle sensors are communicating correctly, no error messages, and within expected range and position.

4. Field AB lines are present/correct and distance settings/angles to join the way line are being met

As I understand it, although the actual GPS rollover date anniversary was on the 6th/7th of April, quite a few receivers due to the way their software has been written will not “realise” the fault until later - I’ve heard November this year mentioned by certain manufacturers. Unless of course they’re up to date / patched already.

Fair to say not all receivers are affected by the GPS date rollover error either. Generally only quite old receivers.

Think I might put the sprayer receiver on the tractor that worked today, if the tractor still works that would narrow it down to the ecu-1 on the sprayer wouldn’t it, as the steering motor is obviously still working after my test calibration today. The book tells me I can only get a software update from my dealer even though you can connect that ecu-1 to the internet.

By all means, if the fault moves (or doesn’t) it’s going to narrow down where your problem lies.

We've had trimble/cnh guidance for about 8 years now and get on fine with it.

It’s better now than it used to be after several software updates, still wiggles occasionally but I think that might be more due to the Maxxums rather vague steering.

The chap who’s been driving our Deutz recently says the GPS always plays up late afternoon, he’s been mainly harrowing or rolling etc so he just takes over and steers himself.

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?

If you delve into the menus the tractor can actually see more satellites than it says it can, but I believe it has to have the same satellites in common with the base station in order to use them for correction?

 

[Wombat]

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