the F7945MC2200 is an integrated circuit that is mounted on a renault capture card. Since the card was not recognized by the car, I disassembled the card and re-welded the inductor which was causing problems. Now the card is being disowned. However, when disassembling the card I damaged some components around the F7945MC2200 and now the remote control doesn't work. If I could get the integrated wiring diagram I would restore everything.
