I'm trying to check all the signals from my ecu. I have a problem - when i switch the ignition ON my immobilizer indicator is flashing and the ECU indicator firts lights on but after few second it's slowly dissapearing (i hope you understand me). My immobilizer isn't locked. The problem is that the ecu is acting strange and can't communicate with the immobilizer. That's why i want to check all my ECU signals (like earths).
I hope you understand me
