Did a diagnostic code read through the head unit. Does anyone have a decoder ring?

48BNCON for example

 

48B is the physical hardware address number. Normally the device name is shown for known devices, but if a device is unknown to the system, it shows the 3 digit physical hardware address instead.

NCON = the device was previously present, but does not respond in diagnostic mode. Check power supply wire harness of the device and check AVC-LAN of the device.

 

Is there somewhere I can see what all the codes mean. Will Tech Stream see all of these?
