MC68HC05B32 - Big problem - Scenic UCH

[LucasDChaos]

Hello guys,i have very wierd problem with this mcu(Scenic 1.9 dti 99'). I desolder chip from faulty uch and cloned it with xprog-m to another uch.Now after soldering them back to those two units they stoped to work.Nothing ,no immo led central locking etc. I understand that something could be wrond with that one witch was programed,but first one was just readed and solder back.Have you guys had same problems with renault uch? I was desoldering it using hot-air.Any clues? Cheers

But why that first one stopped to work only after reading and soldering? I'm wondering what was the reason...

[antwnhszr]

your xprog-m don't read well the mcu with result now you have this situation.....now you have lost all the data from your car and the one thing do you make is only immo off....

Ok i managed to start original uch to work(faulty resistor after soldering :( ).Problem with this unit is no led blibking and immo dont recognize keys.I will try to make the second one reprogram again.

[antwnhszr]

put the mcu from uch car without any modification on uch donor....and start your car

[LucasDChaos]

Mcu switched into donor uch - the same problem. No immo led,wrong key code,sometime showing antena power fault. So it looks like problem with dump inside motorola... :(

[rokibar]

put here dumps and will know is problem there

[gokart]

MCU is faulty therefore the dump is incorrect.

[elephantul]

original dump is faulty, i have exact same trouble, solved by put another uch, make new transponder, virginize engine ecu

I have 3 cases these Megane, Scenic 1PH2 without immo light.
All these case came when client lost all key 4D60. Renault tried recode with ID46 inside and UCH dump corrupted.
My first case solved: replace new used UCH like elephantul said (new key from uch, virgin ECU EMS3132)
Seconde case: Found used ECU + UCH + key EMS3132
And the last: Virgine Sirius 32 + emulator.
Also can put inside virgin UCH dump and recode with Clip (not tested yet)

Here is dump from Uch
351543
What you guys think?

[rokibar]

pin code: 67326425 transponder 4E
all keys eresed. if have key data put tham here maybe halp

[lion0304]

Just done another yesteday.
First i think replace by used new UCH (ihave one), make key and virgin Sirius 32.
But it take many time, so i virgin ECU, put in sirius immo emulator.
Car start the first time key turn.

[LucasDChaos]

Thanks rokibar your pin code is correct.But no key data so i'm gonna cut immo in ecu.Is there option to get 4 digit pin number from uch dump?

MEGANE / SCENIC UCH UNDER THE INFLUENCE OF LOW TEMPERATURE CHANGES CONFIGURATION TYPE 1 TO TYPE 2 OR with the 2 IN TYPE 1 ERROR IS ENOUGH DISH RECEIVER clip configure AND IS OK:stung:

[gokart]

This system uses 8 digit pin code. It's different from the 4 digit systems.

It's only a temporary solution.

[LucasDChaos]

After immo off in ecu car is running ok again.
