Hi,
392-650 it is a hardware failure of ADC sensor shutter. ADC sensor is a part of MOB sensor. You need a tech for clean, unblock or replace MOB sensor.
Good luck!
We have been getting engine failure with red light. The code is 392.650.00. I can't find any information when I google that code. When the machine is turned off then on it's ok for a while. Any info or help regarding this? Thanks in advance.
