Default Help with pending fault code P1C07

Help with pending fault code P1C07.

Testing the status of a HV battery pack in my Karma.
Everything works fine, but I get an pending fault P1C07.

I suspect that the problem is related to a relay in the HV battery pack, but I hope that someone on this forum is able to shed some light on the problem…

Best regards from Sweden!

P1C0X codes deal with HV battery cell deviations.

Thanks for your swift reply Ira!
First chard sins storage and I suspect that one cell is weak.
Will now perform a few charge cycles and monitor the result …

Hi,


You have a problem in module 14

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:
P0A27
P0A29
U110F

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!
