Please help us help you by providing the year of your Volt. Is it a 2011 or a 2015? What is the mileage? Where are you located? How did these errors start? Do you have a check engine light or any other messages on the screen? What happens to the light on the dash when you insert the charge plug?

I don't think you tried very hard.

Based on the link to the diagnostic code PDF's I posted above,

U1838 = Lost Communication with Battery Charger Control Module on Bus H. Detects that CAN serial data communication has been lost with the Battery Charger Control Module on Bus H

P0D39 = Battery Charger Input Current Sensor Circuit Range/Performance (AC Input Current SensorRationality). DTC Fail Sets when the AC Current zero offset value is greater than or equal to a current threshold.

It sounds like you have a faulty component that needs to be tested and possibly replaced. This process is detailed in the other link I directed you to in the Similar Threads section below. https://gm-volt.com/forum/showthread.php?327347-DTC-U1838-CHECK-ENGINE-LIGHT-ON-PLEASE-HELP
