Has anyone ever had this code?

 

I had just finished driving about 100 miles, highway except the last 10 miles were super slow crawling through neighborhoods. I had stopped for lunch, and when I turned the car back on, I had a check engine light on (both the little wrench and the engine light). Message said to check the manual. I did that and really only found something about bad fuel or catalytic converter problems. (I did indeed get gas on this trip).

 

So I stopped in at an Oreillys and they plugged in the Bosch OBD2 scanner. It gave me the P0DE1 code but no details ("No DTC definition found. See service manual."). 

 

Car was driving just fine, so I drove home and didn't plug it in. Today, the CELs are gone. 

 

Anyone have any experience with this?

 

I found these results online:

So something related to the balancing circuitry, maybe as a result of some bad cells?

 

Any thoughts? Thanks everyone.

The service manual says:

 

This DTC indicates cell balance circuit N is stuck closed for 2 consecutive power cycles. CLEAR the DTCs and REPEAT the selftest. If the DTC is still present. INSTALL a new BECM.

 

Sounds like something in the electronics. Just wait and see if it happens again.

What does BECM stand for?

Battery Energy Control Module

 

A common name for that system would be BMS (Battery Management System)

Yes, colin21, I got this code yesterday.   At the time it happens, my battery was down to 0, even the hybrid battery is empty.   Charged it up, and the code was gone.  

 

Still I am a bit uneasy about this.
