Changing hours on JD tractor

[crowbareight]

Hi can anyone help with calibrating the hours on a John deere tractor.
Have changed on varous other makes except these.
Need it as we do exchange units but need to zero the hours or at least lower them.
:pepsi:

post your dump and mcu /eeprom type

[crowbareight]

Opps forgot to add its in a NEC processor
I have a lot of programmers here but this is a 52pin QFP
Here is the numbers on it
All I am looking for is the pin outs as may be able to read it with a nec programmer
Motorola ZC86538CFN
Any help ?

And the Mask Number mate .....Looks like a 908 maybe....
Need the Mask ....

Motorola/NEC ......? sounds strange mate...

Sorry to screw up somebody elese thread, would you be kind enough
to explain in thick peoples terms what the 'mask' is and why you need to know. Somethings i'm ok, something no scooby doo.

thanks

Its a five digit number and letter combination for Motorola Proccessors mate ... Lets you ID them ..when the Processor type is not on the MCU .. like the one above ....

I posted these a couple of days ago...

*CONFUSED* Without meaning to be totally stupid, or anything
then where does crowbareight find the number you want?

*EVEN MORE CONFUSED* Why are you asking for the mask number
when you have these awesome usefull looking PDF files?

Sorry to ask stupid questions

(If you feel the need to tell me to FRO feel free)

No probs mate ...eg..ZC86538CFN Means Diddly Squat.
Below it there may be 0H56A....telling us thats it a 908az32 processor ...Simples....

so if i walked into a pub and said 'my laptops better than yours'
untill closer inspection, pointless saying anything, thanks.

so you now have the mask number, what is your next plan of attack?

if i'm boring you just so.

[crowbareight]

Ok chaps here is the rest of the info on the chip
ZC86538CFN
UHER 248030
OF62J
ZZGG9507

Also on a newer ecu the following
ZC99124CFN
UHER 248186
OD60J
QQCK9808

Hope you get me some info on guys !
Cheers !

Hi!

Look it up mate on the Nice pdf's... HC05 B16...mcu ...Now we have a starting point....

Do you have a HC05 programmer mate....? ETL ..or UPA ?

If so then read it and post the dump...

[crowbareight]

I have various programers for dashboards etc,
But looking for a Bee+ programmer from Santa !! lol
But will have to surfice with my basic william programmer & a few china specials !!
Have the software ok but looking to see if my nec dash programmer might have read it.
Its more for the 78's
But its one of the wire on type.
& of coarse the Big magnifier & the specs on to see the correct pins !
prefer the adapters & just set the chip into them though !
Alot lot easier !

[cammy25]

He is still talking about NEC:hmmmm::hmmmm::hmmmm:

Its motorola not NEC.

Use UPA or Xprog to read HC05 friend. Now we know its HC05, then calculation of hours should be easy (4 bytes maximum).


@Kareszka
where did you get the mask id program from? i mean from the screenshot.
nice one

[kareszka]

Hi!
If the program is needed I upload it.
Regards.

[PremierD]

That would be handy mate....Save me looking up My sheets...

[crowbareight]

Ok chaps have got a new x progammer T on its way to me !
As soon as I get it I will load a dump on here of the Dear John so you Guru's can have a play with it (Should have payed more att in Electronics )
Anyhow have any of you looked at the chap looking the hours sorted in a dump of a Deutz Agrton ?
Its got a load of + & - 's that has me lost !!
But :stupid:me seemed to have missed this bit in class !!
Anyway take a look at it as I would like to have these on my list of machine hour checkups !!
Thanks again for the info & heres one I found when hunting
Pdf file on the very chip I was hunting down !

Its in progress mate ....
Have read the Mcu chaps but is any one good at working out the hours from my dump
Not sure what the hours was on this one though but will see can i load up another one
Only programmer to read it was ETL's as two others were not able to get past the security lock
in file attached

Ps any one out there got a buddy that can repair HDD by removing disk to an other after head is screwed???
All my automotive software on it !!!:dong:

You need to read it again mate ... And change the jumpers ... the dump is shit....

[Meat-Head]

Ah, that's good timing, got confused last night and accidently typed www.93c46.com (http://www.93c46.com) whilst looking for franky vorn, and it links to some us site
that sell the kit to do this. Will mean something to you, but there are model numbers on their homepage, which you mite abale to use

Quite expensive kit mate ... to do A few Tractors ..And mostly American Shit .. But Thank-you for the thought ...

Second dump file of JD BCU in BIN format

[PremierD]

Second dump file of JD BCU in BIN format

Hate to say it mate ... but its the same shit ...but in Binary....You need to read it again ... But Change the jumper settings on your programmer ....Untill you get somthing that is NOT like the attached Dump

[crowbareight]

Have checked the Jumper Pd, but seems to make no differance,
also other chip reading the same.
I am going to try another board as these first two chips may be buggered.
Will try this other one and i will see what it reads.
Wonder is the desoldering bit station putting too much heat into the components ? 275 C ??
Will they still read if the ETL unit has got a red led(ie the security led) on all the time even though the green/yellow read light (middle led)is flickering indicatng it is reading
Power one is also green & ok
Or will it have to be unlocked with the software
Ie to give full access to the buffer file?
:help::stupido2:

Red means it is sucure... and will give you the shit that you have been getting ....The heat 275.. is not hot enough to damage them ....You did select the second option down ...? then Highlight the second column option ....? ... If so .. if you look at your table and you have the correct MCU jumpers set ... make sure that the connections are clean ....

It needs to unlock ...before you will see the correct dump mate ,,

[Meat-Head]

Unless i'm confusing you guys with other users, can't you both stand on the cliff edge and throw the circuit board across the sea and let PremierD have a go himself

[stasgr]

hello friends.
is possible to send you the bcu box and to change the hours

[stasgr]

im from greece

[stasgr]

any interest?

[crowbareight]

Hi stasgr
I am still trying to get these blighters sorted but work in progress !
When I get the hours cracked I will PM you where to send the BCU
for the 10's

[crowbareight]

Anyone want to have a go at cracking this one ??
Hours are 9614
And the dump is loaded below !

[Sheer]

Hello Guys!

i'm currently working for finding the code...i've been searching a way to read the ?P (ZC99124CFN) all i know is that ?p could be a 68HC705B16...but when i try with a full compatible programmer,it seems that the device is protected!

Is someone able to give me All the explications (?p?, bin...) with the *.bin in order to start to understand how JD have protected the hours.

i've been cracked the hours For JD 6100-6400...

thanx.
Have a nice day

[Sheer]

you've done a nice work....i'll try to programa 68HC05B16 with the last programm (9614h)...i will post the result as soon as possible...
Stay tuned

[Sheer]

Well, before tested it, i think all the program you've put on the web are just the "EEPROM" part, it missed the "main part" of it in order to test it under a BCU...Is anyone be able to post ALL the program...PLEASE..
and i will tery to understand the hours...


Thanx....

[crowbareight]

Hi Sheer !
Well I have tried to read the 68hc mcu but with locking & unlocking I get the same result.
Have tried 3 differant programmers to read & only one can give me what you see so far,
But however the hours may seem to be locked in this section as I have tried four different units now (all with 9900 odd hours) & the eproms give different readings in certain lines of the code,
Now I have been looking at the Alfa cars dash & they use a simlar chip but the miles are spread across the same section as the hours on the JD BCU.
So I have been trying to find the hours amongst the lines & which code changes with the hours,
Now I have two units with only three hours of differance & I am going to see what has changed,
Now maybe I have not read the whole unit to find out ,but have you been able to read it ?
And with what programmer & how ?
Have used ETL unit & only way have found to unlock is by setting the whole eprom to 00 00 00 etc & reprograming it as so.
Yes beleve it or not but this unlocks the bugger, & the chip reads as before as though it was never unlocked !
But yet etl board states unlocked chip.
By this stage I am getting More grey hairs per day !!! lol
:dontknow:

[chupete]

As it's all about the change of hours? I've been tinkering and have not succeeded so far

[neptune1]

Hi, just letting you guys know that I sent 3 6410 Bcm's to Prospeedo and no problem any number you need, this Guy is Good.
He charges $600 a piece if you need any done. Hope this helps you out!

[crowbareight]

They still have not cracked the 6600 68,69 series yet !!
Anyone can do the others as he had even been asking me for inside info !


As all the info is logged on the BCU unit & not the standard eprom on the back of the clocks as on the smaller models.
