Hello
I got clio II 1.4 16v,2003 with problems on its UCH (main problem with lights blinking,flashing and relays clicking in UCH).When I move black 40 pin connector, sometimes relays starts or stops clicking, so I decided to squeeze all pins,sprayed with contact spray,I also soldered all 40 pins on pcb and all relays..nothing helped
I read on the net, that is this common problem with decoupling capacititors under 40 pin black plug, so I must repladed UCH with anoter one(I didnt find it yet)
My question is;
It will UCH work if I solder 93c66 eeprom from original to donor?
Can I read eeprom(16bit or 8?)
Whats the procedure(step by step) with clip to reprogram the donor UCH if somebody of you make me eeprom virgin?
UCH-N3 P8200272302A
Thankyou
