Volvo S80 2005 CEM and ECM Sync needed

[LOSTAGAIN]

Hi ,
I have a 2005 S80 2.0T with a missing ECM, I have gotten a donor ECM and need help to Sync the ECM eeprom. This CEM is a CEM-L with Serial Number 00004XXXXXX. Heard that this particular CEM-L Serial range is more challenging.

CEM-L Part Number: 30682981
CEM-L eeprom: 93c86
ECM Part Number: 30668478 (bosch 0261208289)
ECM eeprom: 95080

I have attach both the eeprom files.

Appreciate any help you can offer to help sync the ECM EEPROM.

maybe that's why it's unknown

can help if you will read M30835FJVGP

[LOSTAGAIN]

Thanks Unfortunately, I don't yet have the interface to read the M30835FJVGP chip. I only have x-prog v5.5 and the UPA programmer at the moment.
Are there any other programmers that can read this chip other than the E8A and Smok programmer ?

Believe this is due to this CEM-L having Serial Number 00004XXXXXX. Seems that most of the tools only do the CEM-L with Serial Number form 00005XXXXXX.

Cem dump look like crupto!

Clon tango not work with crupto cem !
About original tango .....:dontknow:

Any Veteran able to help? Pretty sure the CEM eeprom read is good.

eeprom is read correctly, for further work it is necessary to read the CPU from CEM (ori xprog, orange5, smok)

[LOSTAGAIN]

Thanks for the advice everyone.
I looks clear that I have to read the M30835FJVGP chip.
it will take me awhile to order a programmer that can read it. Some questions,

1) can it be read in circuit?
2) read in the forum that I need the CEM PIN to read it else i might end up erasing the data on it. Is there any special way to read the Renesas M32c chip?

here is a diagram from xprog...
don’t know anything about the pin (maybe there are shamanistic methods like in Chinese cars) I do these machines only by dumpsdon’t know anything about the pin (maybe there are shamanistic methods like in Chinese cars) I do these machines only by dumps

where is your dump?

[Ivan0rzz]

Hi guys, I need help, my cem got wet and it's my turn to change it. I don't have data from the old cem. The eprom was sulfated. I only have micro CEM reading. Can someone match this CEM with the original ECM of the vehicle?

1. dump CEM is damaged
2. eeprom ECU read wrong...

[kaponne]

cem flash is ok
cem eeprom have lost data , can be restored
you should read ECM eeprom: 95080 correctly
