load this and post the result

[giuseppe1374]

ivan have you solved it?

[carmageddon]

my problem I found to be the ecu, UCH, the one that receives the code key, handle the boost to the motor d start-up, the block immo etc etc.

the ecu works perfectly with the original file, I want to clarify that in the boot fgtech works why? well, but writes to***** the area and the car is not starting (tested pi? times with the original file, then I unsoldered the eeprom and I have written to the table with the programmer and all ok).

returning to the UCH, there is a repair/modification/intervention HW or SW to do to fix it or ? from replace?

most of the times, the behavior of the light ? one of the following

- the led flashes slow (bollard), key to on and indicator light is blinking fast (the car that is not allowed? start why? without the consent of the UCH, and then l pulse to the electric motor d start-up)

- the led flashes slow (bollard), the key-ON and lamp fixed (the car that is not allowed? start why? without the consent of the UCH, and then l pulse to the electric motor d start-up)

sometimes instead of the login ? exact and everything works regularly...when the car works regularly in the light behaves so? light blinking slowly (bollard), fixed when you turn the key to on and then off (a sign that ? everything is ok and consent starting, start-up ok).

if I switch off the car starting after a regular and appearance 5 seconds for the light to return to flash not c ? pi? the consent on the part of the UCH, and then the starter motor d starter does not turn, this with all and two keys supplied

the via ir? simple according to me ? to replace the uch with a used one and try it out, depending on the league you need to replace or clone the micro, or replace the eep if you post a photo of your pcb uch maybe we see, otherwise the new uch and alignment which contains special equipment.

summary of the situation :

I found a UCH identical in the codes, I unsoldered the mpc and e2p I moved to the new UCH (from the collapse of an identical car and working perfectly, tested this morning), and nothing to do, is the fault ? the same gi? described....sometimes it goes and often does not go.
I have changed all the fuses and relais in the box next to the battery and checked the internal ones on the side of the dashboard, I have changed the antenna on the block but nothing... the car has always the same defect

[guidotacco]

controls on the rear lights if the mass ? good otherwise, get a cable and try to take it from the battery to do the test

[carmageddon]

and everything perfectly in order on all the lights, controls, internal and external, arising from the uch...gi? controlled

ok,I'm on a clio dci I solved as said
