HELLO,I heard that anything was ok with the car until it blows the turbo then after installing new turbos a technician was called to clear the faults but while clearing the faults with Launch x431 anything shut down, no ignition on when you press the start\stop button. checked all fuses they seem ok, diagnostics was not possible since there was no ignition on so i gave direct power to fuse 19 and i was able to diagnose some modules and i get no communication to the Body Control Unit in all the modules i diagnose, please help where to start from.
