Hi Yani, please help, I tried to connect to my Grande Punto 1.4TJet with elm327, but failed. It can connect to my Punto mk2 perfectly, and also AlfaOBD connects to my Grande Punto with the same ELM327. Please help solve my problem
Error message: ELM327 ECU Connection failed.
No response from module. Check if interface is properly connected to the vehicle and vehicle key is ON!
