18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low
Possible Causes

Cables on the Battery were removed
Battery weak (voltage)
Generator Disfunction

Possible Solutions

Check Battery Cables
Check/Replace Battery
Check/Replace Generator

Special Notes

If multiple Control Module have Power Supply Faults stored, it's most likely to be one common Problem like the ones shown above. Otherwise when only one or two Control Modules have such Codes stored you better start searching at the individual Power Supply of these Modules.

Terminal 30 means unswitched battery power that is supplied even when the ignition is off. This is not referring to any physical terminal numbered 30.



Looks like the second code relates to the battery, which could explain the radio problems. Take a good look at your cables and make sure they're good. Also looks like you have an EVAP issue, based on the first code. Hopefully this helps. I got this info from: Ross-Tech Wiki in case you want to investigate more.
