About a week ago the check engine light came on. My Karma is running fine and there does not seem any problem in charging the battery. I check the comments on the forum and I ordered a OBDII code reader from Amazon. I checked it out today and got two codes- POA80 and POA7B. It seems that both these codes have to do with some problem with the battery. Since I have the codes I attempted to erase the CEL so I would have my speedometer back. It erased for about 2 seconds and then the CEL icon came back. Should this be checked out by someone who has the Fisker software or is this another quirk in the Fisker software? Would it be advisable to do a hard reset? Thank for your input and help.

The faults originate in the battery control module which commands the engine module to throw the light. Erasing only the engine codes will not clear the battery module of codes so it will keep commanding the light to come on unless the battery codes are cleared with fisker software ot hard resset but then you losethe data of what went wrong so I'd say get it to someone with a Fisker scan tool for diagnosis.

Thanks FiskerPhilly. I'll get in touch with Lormax. It's about a 80 mile drive but that is nothing compared to Toronto and other owners!

POA80 and POA7B Codes

I have the same codes (POA80 and POA7B) on my car.
They popped up when I intentionally let the battery run down to 0% remaining. I did this because I wanted to cycle through some of the gas that was in the tank before it turned to lacquer.
As soon as my power meter reached 0% the CEL light came on.

And like others that have tried to clear it ...mine just keeps popping back up.

I am nowhere near a Fisker mechanic :-(

I've tried the hard reboot, at least I think I have. I disconnected the plug under the hood and waited a while before plugging it back in.
Didn't help.....

Are these codes something I should be concerned about?

Just a FYI...I'm at about 6,500 miles on my car.

Thanks,
Special K

According to google search results, P0A7B is "battery control module requested MIL" (i.e., "I, your Check Engine light, don't know why I'm on, except that he asked me to come on" with finger pointing to BCM).

P0A80 (note, these are all zeros, not uppercase Oh-s) is "weak cell fault" and on a Prius means "replace battery pack". On a Karma, I suspect it means "word-that-forum-software-replaces-with-stars, if only I lived closer to HarleyGuy or FiskerPhilly" :D

The root code is in the BECM and it will not clear with a reset. Becm maintains its memory, thus the ecm code clears w the reset but instantly the Becm recommands the MIL light. Im not that far relatively speaking and have serviced several VA / DC owners.

It will be a while before I can travel up your way.
But.....if you happen to be coming down to Northern Virginia I'd be happy to have you come over to my place or I could meet you somewhere.

I had this code P0B8C for 6 months
Turn on in only when range drop to zero and engine start. Usually come on when I turn the car off then on
.. We checked it before on Fisker tools... Travis ,, said one cell reading 200 less than the rest . The 35mile range 5 hours charge time the didn't change.. So I'm not worried

Just got this and P0B80 today. Will not clear with hard reset. Is there any way to clear it without having to pay a tech to come here, i.e. a way to clear the BECM memory? Biggest pain is not being able to see the Digital Speedometer readout because of the stupid check engine light. Is it possible that if left plugged in, and it is a cell imbalance that it will rebalance it and clear the code? or do BECM faults latch until cleared by a Fisker tech device?

You Can get an ODB reader with reset function. There are several threads about this.
You can then reset the code to get the speedo .

But gone is gone. The tech visit is not always a bad thing and wiping out the codes doesn't help him a lot.

Stefan, I have an OBD-II reader and reset the ECM but as mentioned earlier in this thread, it does not clear the Battery ECM so the fault returns in two seconds.

How do you fix it then? CSP? A hard reset didn't work or did he not wait long enough? Curious how you fixed it?

It really depends on the fault if you have one or two bad modules the code won't always clear if you charge the battery to full then try resetting . If the HV battery looses its SOH that can only be repaired with software which consists of reflashing the BECM.
The car really needs to be scared with the Fisker scan tool to see what's causing the fault.Im working on getting a laptop back working that FiskerPhilly and myself can send out to customers for a fee and do a remote takeover and see what's going on.
