Flash for UCH N2 X76

[Col19]

Hi friends

I wanted to add a Kangoo 4x4 key, and as luck would have it when I was learning the battery my battery died, so the warnings stay on permanently and I no longer have communication with uch.

UCH-N2-X76 / P8200094768

I had read the eeprom before launching so normally it is intact, I think the flash is stuck in boot mode. Is there a brother who has flash + pinout please, that would be a big help to me.

Thank you in advance, Respect.

Did you disconnect the battery for about 10 minutes?
It could have crashed. I don't think there's anything wrong with flash.

Thank you dear friend, I haven't tried it but I dismantled the module and put it on the bench and still no communication, I thought it was perhaps stuck in startup mode, no alarm, thank you again for your support, respect to you

Disconnecting only the UCH may not help. I repaired Renault Fluence and after calibrating the ECU, it stopped starting. Disconnecting the ECU power supply did not help. Only when I disconnected the battery did the engine start. Do you have Renolink? What microcontroller is soldered there?
