Hello, 

Has anyone ever used transtron module 70, for flashing Case  excavator with 4HK1 over OBD?
I managed to read without any problems, but I  have some people telling me that writing tends to fail, which is why people do them with KTAG in BDM.
Any truth behind that or just false stories?
Since I dont have KTAG at my disposal I would rather not take the risk, if the mmc obd solution is still rather in beta development stage.


 

Hello , you can have problem only if you write BAD EDIT SOFTWARE. In other cases all be ok!

Thank you for such short notice.

looking for ecu pinout transtron M3SC for isuzu 4HK1 it has 60 pin connector and 94 pin connector. Thanks

 

i asked support few days back,support tell me to ask "Bruce Willis' in forum. It's exact same ecu as "4KH1 safe" thread

I guess i can try support again

5 days back you don't send ECU photo and i gave link how need to ask pinoout, i gave you th same link as in my last post on this theatred. And i don't write you to ask any body, just link how need ask pinout in support, with ecu photo and connector photo.  Don't need write here, write to suport 1 good request and wait answer.

Hello 

mid it possible to recover if bad edit software was flashed and now no coms ?

Hello yes, but only with Ktag, dim sport, piasinin etc 

Hi 

I tried with ktag, trasdata and no good can’t get coms, I tried read procedure and write procedure and can’t get id on ktag or trasdata 

please advise

thanks 

We support only mmcflash, advise you need get from support ktag and trasdata

my mmcflash worked great reading and writing this transtron without open ecu,hopefully you haven't damaged ecu already

Some examples of tools I've made

very successful

case cx300c-350-370 transtron ecu sh7059  reading 1h 50 min write 30 min

isuzu novo 4hk1e6 transtron sh72544 1h 30 min reading write 10 min

isuzu dmax 4jk1 reading 1h 30 min write 10 min

 

 

who has a pin out ( bench) of the ECU.

have a hitachi excavator do not know where to connect obd.

https://mmcflash.ru/forum/topic/1811-request-ecu-pinout/

Isuzu transtron M3SC Support pin out for read write ecu via CAN BUS on table. this pin out 100% with mmcflasher i have tested my hand 

Ground - Black 

12V / 24V - Red 

Blue - CAN L

Yellow - CAN H 

Today I tried to write the same ecu in eobd, it has been read perfectly, but when I went to write the mod file, it told me correct checksum and the writing has finished, it showed write ok, but the machine does not start, now I can not communicate with the ecu in eobd, what has happened?  How can I recover the ecu?

Hello I can Help you. please tell me more details. what is engine model? what is ecu? post some ecu photo too i can help you. first at all write ori file back. and check ecu communication ok or not. 

Hello friend, the ecu is the following, it is a case cx300c machine, now I cannot write the ori file, I do not have communication with the ecu, what can I do?  Do you need more info?  Thanks

You write bad bin file. Now recovery only piasini, k-tag etc

I have to admit that the mod file was wrong, I wrote with transdata the ori file read with mmcflah in eobd and the ecu came back to life, later I re-wrote a new mod file with mmcflah in eobd and the write was correct, mmcflah works on this ecu correctly

I report a new news, today I have written modified file in case cx300d in the obd diagnostic connector, I have read and written and everything worked perfectly,

Good day  i have a 4hj1 isuzu transtron ecm and need pinout for mmc read see attached pics thanks
