DTC P2C85

Do I have to worry about this? No errors on dash but seen while I was in Forscan. Do I have a bad HV module?

That is not the DTC I got when I had a battery module go out of spec and require replacement. It was P0B24 in the BECM module. Could not AC charge and got the Service Vehicle Soon warning in the dash.

If you have CarScanner you can check your HVB Voltage module variation (as shown in my link above).

Thank you, not a lot of info on this code unfortunately.

Based on below, I would bring it to a dealership and if looks like a serious issue, send the "Lemon Law" paperwork to them in advance
