Hi

i have an UCH from Renault Megane 2005 (UCH:8200309690 PDB:820326031)

Everything work fine in that car except the trunk, not open..........

the wiring is ok, i suspect the UCH, anyone knows if it is possible to repair it? What it may be the problem?

Update

i cant find anything in pcb.... (and i dont have the car....)

i talked with the owner, the problem starts after he discovered that the negative battery pole was loose.....

i suspect the eeprom is the problem......

if i read it is possible to repair? or i must make virgin and adapt it?

Thank you.....
