need help reading mcu

[ninja123]

Can anyone help me, trying to read HC05 mask 0D62J QFP64, with xprog, mcu is from 1998 mercedes sprinter.

xprog says device is silent, I try with power supply too.

Any diagrams or settings would be great.

Thanks in advance, ninja

Did you set oscilator to other value like 8000000?

[ninja123]

I tried that, it was set to 16mhz, i changed to 8 but still same :(

Remove MCU from board and solder to qfp64 adapter and you can read it without problem.Dont waste time to try read it onboard with xprog.

[elmassioui]

friend if you got message device silent on first time that mea your chip is errased.xprog not good tool for this mask.best tool is etl705

:)

[kelekele]

Last week had same immo box and just removed mcu from board and job done in few minutes.Xprog skip security bytes and dont erase mcu.

[igorr]

with that mask I have problem to when I tray to read it with xprog so I use etl clone

[king alie]

hello
xprog can do it 100%
but it better to buy adapter
I use it dailey

[ninja123]

i have removed mcu and soldered to adapter but still xprog will not read it, can anyone give connection diagram or any other info that i need to use xprog to read this bitch?

Did you solder xtal 8000 or 16000 MHz to adapter near mcu?Without xtal you can't read MCU.
Which adapter you use?
You must use this adapter

284185

[datapage]

284196 teted 10000 ops , 0d69j 62 ak400

[kelekele]

That is not solution for hc05.

where to solder xtal on this adapter, and where can i get this from?

Thanks for info, ninja

[kelekele]

You must get this adapter when buy xprog device.
Here is pic with marked pins for xtal,but soldering is from other side of adapter.Try and you will see what is magic of read/write hc05x16/32 with xprog.

And guys,if this helpful dont be shame to hit thanx button :D

Mask D62J ,D69J tested 100% successfull.

[obdsystems]

I always like reading your posts ninja cos your problems become my problems :)

[ninja123]

lol - so is that your admittance of being behind the times :)

Only joking mate - do you know where i can get the bloody crystal from? Ive stripped out a few immo boxes and ecu's to try to find on but no luck yet :(

ninja

[kelekele]

Man,vag comfort modules,some clusters with motorola mcu etc.
You can put 4000,8000 or 16000 MHz just set in xprog same frequency.

[ninja123]

ok, i find some but no markings on them, any way to test what is Mhz?

Here we go -

4Mhz should do

No bugger wants to help me with my posting OJ66D - not as popular lol

I think my Chryslers SKIM MC68HC908AZ32 is dead but i have plan to rewrite VIN on either replacement cpu or scrappy one.
So problem solved (i think!) with matching this way

yeah ninja i seem to be doing more ecu repairs than keys now. guess just the way the jobs go :)

Need frequency meter or osciloscope for that.Why not just remove xtal from immo box?

[ninja123]

remove it from the same immo box? ok, but what is mhz of this? 16 or 8?

Thanks for your help here mate :)

ninja

[obdsystems]

You want the 2 pin type. Not the 4 pin or surface mount type. go to my ebay link and u will know what to remove on the pcb :)

8Mhz should do. They are marked in MHz so 2, 4 ,8 20 MHz will be on top of chrystal

- so u may need one off another board

[nicocr]

buy a upa! never had any problem with merc immo on board

[MarkPRP]

Ian, Just bring it round to me. Ill read it in seconds and show you how!

If you in hurry,remove xtal from same immo box and finish job.First try with 8 and if not read try with 16 MHz.For next time buy somewhere spare xtal-s 4, 4.19,8 and 16 MHz and make stock .For this xprog adapter best is 2 pin xtal ,like member obdsystems say ,but smd with 3 pins also can be soldered just middle pin is not in use.
Many peoples from this forum helped me,and i just do same thing ;)

[kelekele]

Man,i have original upa and i think is too risky read this mcu on MB with she.Upa can't skip security bits and erase eeprom in that try of read mcu.If you have empty mcu ,upa can write dump without problem.Only problem is reading :)

[rivalryan]

I have UPA also, I use another programmer normally though. You can read mask J66D fine no security. L52H has security - enter security bytes F1 6A FA 04 E4 DA FA 04
and this will also read fine. wont do 0d62j as far as I know

did call you mate but no answer :(

And you know how I like to be independent lol!!

ninja

[MarkPRP]

Oh when mate?? Anyway if you want to learn.. Call again!

[obdsystems]

re-flow pads n change crystal settings as suggested and all ok. x prog is good kit
worked for me on this OJ66D

[p1et]

Hi,

Because of the topic, I found same immobox (same MCU) and decided to try read by Xprog and no problems reading on QFP64 adapter without soldering crystal.

[kelekele]

You are lucky guy.My advice is to buy and play lotary,winning is guaranted 100% :)

[tunertool]

Ive got xprog with qfp socket for hc05 reading... would love to see if it reads this... if your in wolverhampton anytime give me a shout and ill try it for you.

That's common it must be.

The HC05 adapter board by secured mode gets the clock signal out of the box through a pin on the long pin header.

[ninja123]

kelekele - worked with crystal, thanks mate :)

steve - this not od66j !!

mark - I hate coming around your neck of the woods - bit like bermuda triangle, once in cant get out!! (thanks for the offre mate:) )

ninja

ps - is there any software that i can load these dumps into, to manage keys etc?

is that wolverhampton in portugal???
