DRB displays BATTERY DISCONNECT. Condition is: Direct battery input to Powertrain Control Module (PCM) disconnected within last 50 key-on cycles.
DRB display will be blank. Completion of trouble code display by MIL light.
I would start by checking the battery posts and terminals. Make sure they are both free of corrosion and tight connection. Then go to your PCM (on driver side front corner of engine compartment) and make sure that the plug has tight connection and also check the ground for the PCM, as well.
I understand that the battery has nor been disconnected (on purpose), but the PCM somehow doesn't receive power from the battery intermittently.
Let me know what you find out.
