I also have two adapters for elm 327, yellow and green. After connecting the elma without an adapter, you have access to the basic functions, to the extended body type, pillows, abs, air conditioning, the computer asks you to connect the appropriate adapter. This applies to Fiat group cars and the full MES version.
There are no markings on my adapters, only colors. As far as I know, there are only swapped pins in them. It's best to hook up to the car and you'll know what you have, if it's from a Fiat at all.
The discussion centers around the use of the ELM327 adapter with the full version of MultiECUScan (MES) for connecting to Fiat group vehicles. Users confirm that while basic functions can be accessed without a special adapter, advanced features such as airbag and ABS diagnostics require specific Fiat adapters. One user mentions having two ELM327 adapters (yellow and green) and notes that the software may only allow access to engine parameters unless the correct adapter is used. A link to the supported vehicles list for MultiECUScan is provided, and there is a query about identifying the type of adapter based on physical characteristics.
