Fiat 500 marelli MJD6DF ecu and mpps strange error on read

[pulsar2000]

Hi,
ealier today had a late 2009 Fiat 500 come in, Assumed was Marelli MJD8DF
and MPPS v21 says can read/write ok,
ECU ID ok
then on read, mpps crash out instantly,
Car cranks but won`t start, Has ABS and Fuel Cut error on dash,
I pulled Ecu and is labelled MJD8DF
but inside is exactly same as MJD6DF so i read bdm using Ktag all reads ok,
I`m puzzled as to whether its possible i corrupt on read ? but it crash intant before any read,
or does car think accident and i do fuel cut off reset, and ecu data is all ok,
i upload full backup, wonder if someone can take a look and see if all data appears ok,
I also upload "found backup" from another dk member for compare,

or is ABS and fuel cut same as immo ? i don`t think so as car cranks just no start,
thanks in anticipation,

Read first whit ktag it's better. More mj8 bricked from mpps. Restore flash whit ktag if not work immo off in flash.
You have kess? Kess can id?

Ok i will write back from my found file tomorrow,
and see where we are,
you think abs and fuel cut could be immo ? or just need reset using diagnosics

You can try proxy allign. But I think your ecu now have some part of file flash missing. Only restore whit good bench file you can restore your ecu

China Mpps 21 is sh.t tool, i had the same problem few years ago.....

When it try to read cut's power from ecu and when ends reading it set back on...

Bdm reading will not helping you....

The ecu is like have set to boot mode...

Try to id with other tool by obd, that will solve your problems....

ok so quick update, don`t use a shit MPPS v21 on this ecu,
appears to have corrupted eeprom area as soon as it attempted a read,
Flash and MPC areas all ok untouched,
MPPS crashed out immediately at start of read,
left vehicle with ABS and Fuel cut out error on dash and no start, cranks ok
i used bdm back up inc eeprom and then flashed immo off,
Car now starts and all ok,
