Citroen C3 VALEO J34P original software

[miki18]

Hello,

Can someone please help me with this?

I suspect I have crashed processor software....

Can someone give me original processor software for this ecu:

Valeo J34P
21586048-9 A
SW9664127180
HW9651696680

For engine TU4A (PSA 1.4 8v)

This is processor ST10F275 and it has 832Kb file.
I can read file with KTAG with no problems but I cant find original file to compare it.


I can connect to ecu and PP2000 can see ecu but when I open ecu properties I can't see any DTCs or any parameters there only this: ???? ???? at all parameters (voltage, temp, rpm....)
I also removed IMMO so that is not the reason for this problem.

Car doesn't crank at all.
I tried someone elses ecu and car cranks normaly just doesn't start because of IMMO. I can get in diagnosis normaly...

Please help me with this.

Best regards

you can take eeprom chip from your ECU and put in another J34p and start car if cannot find original flash files

Thanks dorofteius.

Car started the first time :-)

Looks like mcu software got screwed-up by bad alternator...

Thanks again for help.
