Default 2008 honda civic 1.3 hybrid ima charging but 12volt isnt

I have a 2008 honda civic hybrid ima battery seems to be charging but the 12volt battery isnt. No check engine codes only thing showing up is the battery light. I turn over the ignition and i hear a clicking noise coming from the back. I already got the seats taken out of car to try and diagnose. Could this be a fuse problem or something else? The car has 136000 miles on it.

Never a bad idea to check fuses.

Assuming IMA battery is good.

Bad 12V
Bad DC-Dc converter

The code for dc to dc converter is showing up. It says dc to dc malfunction. Is there a fuse for the dc converter?

The diagnostic code for P0A94 does not reference a fuse.

Diagnostic steps until resolved:

Terminal lug in under-hood fuse box, tighten 7.2 ft-lb or repair if damaged.
Terminal lug in IPU compartment (under red plastic cover), tighten, 7.2 ft-lb or repair if damaged.
Replace DC-DC converter.

Also, while in the IPU, good idea to remove and reinstall all accessible connectors to insure good connection.
