Renault Laguna III UCH problem

[fedez]

Hello everybody,

have big problem with 2x Renault Laguna III 1.5dci, after rewriting flash and eeprom to UCH with xprog, both car DIED! No feed, nobody works on car...
Tried another xprog but the same.

UCH: mask 1L15Y, MC9S12XDT384CAG.
These xprog's are clones, but no verify error...

Can't understand where can be a problem...

hi, did you solved problem with uch after flashing with xprog?

[fedez]

yes, need authorized xprog (I think clone xprog software can't re-lock mcu). These UCH (MCU) very sensitive to crash.

not good, and dump that I readed is ok or corrupted?

with clone xprog usualy reads fine, but if you trying to write UCH is dead

[dyc]

but can i repair with right xprog box when i get it or is uch dead anyway?

It's hard to say... if your clone xprog writes flash ok, no mater if was verify error, there is a hope :)

[fedez]

if you want, post uch dump, I will check them.

latest xprog software 5.5.1: XPROG-box (http://www.eldb.eu/index.php?route=information/information&path=1&information_id=4) flash dump from UCH is good, without error, I "think" eeprom is good too. If I understand correctly with new xprog your UCH start to work? power turns on? Maybe you made same mistakes when flashing?

[dyc]

uch not work, no power on flashed one , what you mean mistake by flashing?

[fedez]

I dont understand your situation... there is two different things.
1. I mean UCH not working when you connect battery to the car and nothing happens, no power at all?
2. when you connect battery car turns on (dash, lights...), but when you insert key and got key not recognized it means immo problems?

So, what situation you have?
