failed connection can bus

[ballesterospiri]

hello. all forgive me for my ingles.haber if someone can help me. I already have the elm327 and the connectors in this case the yellow for my double type 263. I have the free version of multiecuescan and when I try to access the modules it appears error: ELM327 -ECUconnection failed
can bus error.check if interface is properly connected to the vehicle and correct vehicle model.
is it because it is for the free version? or I have something wrong configured
in a couple of days I will buy the paid version and I wanted to make sure before everything is correct. for more information the elm327 was asked to uk idiagnostic and I am very happy with the purchase. but it is costanto to make it work thanks in advance

Probably your interface is a fake elm. Resistor-related faults show the interface compatible, but can't connect to anything else than the engine ECU.

You can test your interface with an ELM compatibility tester software, that will show you which versions - if any - does your interface support.
