Memory device is serial eeprom 93c86 SMD8 package or NEC MCU. For serial eeprom 93c86 expected file size is 2048 bytes. You can read Fiat BSI by OBD2 using Immo tool with Fiat software activation.
For files read by OBD2 expected size is 21 or 32768 or 65536 bytes. Use PCF7936 or Silca T14 – JMA TP12 or CN3 transponder or remote key with PCF7946. Software shows 5-digit PIN code.
Note: for files read by OBD2 from NEC MCU software shows PIN code and prepares keys but does not create new file. You must program prepared keys by OBD2 and PIN code.
IMPORTANT when you want to program remote key : open key and look on PCB. You will find 2 SMD chips – PCF7946 (SMD 14 pins) and smaller SMD chip, which can be with 8, 10, or 16 pins. If smaller SMD chip is with 10 or 16 pins, PROGRAM KEY AS TYPE 1. If smaller SMD chip is with 8 pins, PROGRAM KEY AS TYPE 2.
IMPORTANT: if buttons of remote operate, but not work properly, for ex. button for locking opens trunk, this is NOT A TMPro SOFTWARE PROBLEM. Use other type remote.
