Fixing Codes P0A1F & P1E25 in a dead car using BPCM

[Scotty]

I was at a mechanic shop today and they brought in a Fiat 500e with error codes P0A1F and P1E25 and it couldn't read the full BPCM system status, even after disabling the humidity sensor, doing a 30-hour 12V/HV reboot, clearing codes from 17 modules, and cycling the key over 10 times.

But the problem was fixed by replacing the BPCM with a used one, confirming it was the cause of the issue. I just thought to share with everyone.

So in other words, a bad BPCM can show as a persistent P0A1F and P1E25 error.

Thanks for sharing Scotty,
But what exactly does the BPCM do, and how does it affect the car's performance if it starts failing?

So the BPCM basically keeps an eye on the battery's health and power distribution. If it starts to fail, you might notice sluggish acceleration and potential overheating, which can seriously affect your ride.
