Default Karma not charging and driving

Hi,

my Karma refused to drive, having READY blinking and red HV Battery icon.

From looking at the system, we figured the codes:
P0AFA00 Pack voltage fault and
P1E2700 Upper half pack fault
P0D1700
P0A0C00


(I'm translating, what I understood from the shop):

HVIL-Charge OBCM seems to be OK up to the OBCM, but there is no outgoing HVIL signal from the OBCM.

The assumption was a bad OBCM and a bad CSM. Shop exchanged OCBM and CSM temporarily and everything runs fine.
The EDM also aged a bit and they advise to exchange this one too.



This raises some questions:
- do OBCM and CSM often go bad at the same time?
- are these parts (OBCM, CSN, EDM) to be repaired or do they have to be exchanged?
- are there used parts available or do I need to get them new?


I'd love to get PMs with any offers for the 3 parts.


Thanks.

I never had to replace the EDM or CSM I’ve had to replace the BECM only for the reason it stopped showing the correct percentage of battery life. More common to replace the OBCM .

Thanks Adam,

as mentioned, they exchanged both the OBCM and the CSM temporarily and it worked fine. So, in first place one would think they are broken.
But before replacing them, I want to explore my options.

Is there a chance that these components are not broken but only need some new software?

@all: If software won't help, where to get used or new OBMC and CSM?

Thanks.


PS: For the EDM, I found a thread, where some have replaced the internal Tyco relais by a stock one https://www.fiskerbuzz.com/forums/13...nt-charge.html... which is by far the cheapest option...

Not a software problem its a hardware fault
