The dealer said that the problem was either a bad hybrid battery ($6000 to replace) or a bad transmission control module (also $6000 to replace). The local mechanic tried to charge the battery because the scan showed 0 Soc. , but I'm skeptical of the technique used because over period of a week I kept calling him and he kept telling me that the battery was on the charger and the Soc was gradually coming up. He was unable to get the car running. So I decided the battery was suspect even though Forscan shows 314V. I have installed wire leads to the interlock relay as shown by SKeith (Thank you very much Steve. You are my hybrid battery mentor) and I have verified battery voltage at 314V. Let me add the codes that I'm getting:
a) P1A10 Disable HV battery
b) P1A14 Disable transmission
c) P0A0A High Voltage system Interlock Circuit
d) B2141 Non-Volatile Memory (NVM) configuration failure — No PCM ID stored in PATS

Here is screenshot:


So I have more or less ruled out the traction battery and am looking into the "no PCM ID known to PATS module" code (P2141). Using Forscan I looked at pids in IC (instrument cluster) module and there was indeed no PCM ID stored. I also scanned the IC module in a fully functioning 2010 FEH and it showed that a PCM id is present. I show screenshots below:

I have attempted erasing and reprogramming keys, initializing and resetting PATs module with no success. I'm wondering if anyone has experience with this problem. I am thinking that the PCM may be corrupted. The "Module Experts" https://moduleexperts.com, will recondition my PCM for $200 and I'll probably go that route, but am looking for second opinions. Thanks in advance for consideration and help with this problem.
