Hi,
I bought a elm327 btclone on Ali to activate rearcamera on my fiat 500l. In MES I have all passed test but when I try to go in can bus I habe the error "can bus error.check if interface is properly connected to the vehicle and correct vehicle model". I just removed the 120ohm resistor (my board is like this https://www.youtube.com/watch?v=-tsSYDv-dSA) and connected with yellow cable. I just tried the low latency flag in MES but nothing is changed.

Do someone have suggestions? Thx u

Lately I bought this OBD2 Wireless unit and the yellow cable (checked this with multimeter).

4 - 4
5 - 5
6 - 1
7 - 12
14 - 9
16 - 16

Canbus can be read, buty with Proxi Alignment I receive the error unreliable connection.
Do I need to specify speed or something in MES (official version, for € 50).

Measured between pin 4 and 14, 60 Ohm

Do I need to remove something or is 60 Ohm allright?

Bom dia, estou tentando conectar a ECU do meu FIAT STILO 1.8 8V, o elm327 1.5 está comunicando como pode-se ver no teste abaixo, porém quando eu conecto na ECU, não aparece nenhuma informação, e simplesmente não responde aos comandos, mas a conexão é feita com sucesso, sem falhas. Simplesmente não atualiza as informações. Estou sem cotas para anexar arquivos de imagem para que seja possível um melhor entendimento do meu problema. Peço gentilmente a ajuda de vocês.

This interface is compatible with ELM 327 1.4! Should connect properly with all CAN modules.

Hi,
does anyone have experience with this ELM 327? Which resistor needs to be desoldered to work on the Lancia?

hi, this tool connects only to the engine control unit, I have another modified tool where it was easy to locate the 120 ohm resistor, please can you tell you how to unlock these new models .. thanks
