This vehicle was driven on a street and bounce on a bump and it off. I try to start it and it fails to start.I try to diagonize it and it was not communicating. I replace the ECM with code-free type and diagonize again and it was given only this code. I try to relearn the injectors and it says I should input 4-digit injector code. I loosen the injectors to see the injector 4-digit codes but I didn't see, so how do I get the 4-digit injector code to relearn the injectors?
I attached the screenshot of the diagnostic report below
