How can I recognise an EEPROM CHIP and can I use bench programming through EEPROM to program or register key in NISSAN ALMERA N16 that uses NAT 5 and 6,even using other scanner the Nat immu don't communicate, I connect to Nissan and they gave me a waveform using an oscilloscope and the result will prove if the Nat immu or ECU was malfunctioning but the signal was quite different but can't tell if the Nat immu or Ecu is bad
