New guy on this "Hardware not found"

[klaesson1989]

Hi.

I have built myself a test bench to be able to flash GM ecms. I am using an ELM327 Obd2 interface. I have the ELM327 plugin.

The problem is that TP RT says "hardware not found". When I press the connect button with power on ecm, I get about 40 Hz in the box down in the left corner. If I turn off the power, I only get about 5 Hz.


I know the ELM327 Interface works when I managed to get into ecm with other software.


Ecm I have is a 12200411 and will come from a 2002 Tahoe.


I'm new to this software but I would have been grateful for helping to get into my ecm.

Here is a picture of how it looks.
