What is fuel leakage control & vida errors?

[02V70]

I recently got vida working with a knockoff JRL Mongoose cable. There seems to be a lot of codes for things that I fixed and things that seem to be working like the radio and steering wheel buttons. The codes that came back after clearing them were
CEM-3A08 Relay, heating leak diagnos pump Signal too low
CCM-001F Air quality sensor Signal too high.

The 3A08 error says that the likely cause is 2/143 relay has failed. Since I have had a relay for the high beams fail, it seems possible that this is the problem. I found a relay diagram and this relay is labeled fuel leakage control . What exactly does this do, and what problems would occur if the relay is failed?

For the other code, it seems maybe the air quality sensor has failed. Would anything bad happen if I don't replace it?

Hello! Were you able to solve this problem? I have a 2013 C30 2.0, it just shut off, I did the diagnostic with Vida/DICE and I have 2 error codes, CEM-3A08 and ECM-0232, both with a description of "fuel pump signal too high" according to the code it could be the relay or something related to it, do you have any idea about this? so I know where to start?
