Liberty 2011 Code B210D

Hi,
i had issue with my jeep alternator’s rectifier damaged and I changed it but still doesn’t work probably. It doesn’t charge the battery.

carshop says it’s problem with the computer always happen to Jeep cars and i have to replace the car’s computer. Is this right? Or is there another solution?
error code B210D

The PCM sets the B210D OBD2 code when the Battery Voltage is less than 9 volts for more than 15 seconds.
I would likely suspect it's an alternator fault and finding a shop that can bench test it would be recommended.
Check battery terminals to be tight, free of corrosion, and charge the battery, then load test it.

I second a bench test.
