I’m testing a replacement HV battery in my Karma and the car drives beautifully down to the last mil / km of the battery and the ICE kicks in perfectly. However, I’m getting error cods then I chard the HV battery.
Seems like charging is not turned off properly … I’m getting a warning for malfunction in HV battery and the car cannot be driven. But when I connect and remove the charging cable, the contactors are making their rhythmic sounds, the warning disappears and the car works perfect. Could it be a faulty program version in the HV battery's ecu, maybe a faulty relay or is the module 14 problem as described by Ira and Peter the reason to the problem ...?
Error cods after charging:
In-spite of these error code the vehicle performs perfect after connecting and removing the charging cable (the error cods disappears after connecting and removing the charging cable).
I'm looking for ideals as to what could be the problem and would really appreciate any input.
Best regards from Sweden!
