P1B770 High Voltage Precharge relay Fault

[Thara08]

Hi,

I have a Kona electric 2020. After a unsuccessful fast charging incident, my car had 12 V battery error, when I replaced new 12 V battery a new error "Check EV system" (Yellow triangle and EV sign) showed up. My Hyundai garage is not looking yet.

After a research I suspect Power Relay Assembly is defect and the High Voltage battery pack has to removed and PRA needs to be replaced.

Anyone have any inputs?

I'd give the dealer a chance to do their job and only mention this if they can't figure it out.
