Connecting with ECU with OBD2 ELM327 device

[atharishaque]

AOA, I have a vitz 1.3 2006 japanese model. While trying to connect with OBD2 elm327 device it gives error that it could not connect to ecu. Can any one help me in how to connect using customize PID and how to enter PID for vitz in application and what to enter.

either ELM327 Is Not Supporting Car OBD Protocol Or Device Communication Is Faulty

hope your ecu is on genuine wiring with no jugaars

I have checked the same device on another vehicle and it works fine. The Vehicle was previously checked by mechanic using similar device. That means the car ECU has no issue. I think the issue is PID. OBD2 and m-obd difference may.matter, because JDM vitz is M-obd. I also used a plugin with Torque app specifically for Toyota vehicles.

Entring a PID manually will work or not?
