BCM Chevrolet Captiva

Hello everyone!

I have a problem with a Chevrolet Captiva 2.0D 150cv
I need help because it's driving me crazy!

The problem is the following. The car works perfectly, but when you remove the battery (or it runs out of charge) and put it back on, the car does not start again after 3 hours, 1 day, 1 week... when the car wants... Once it starts, it doesn't give problems again until the battery runs out of charge again.

When this happens, the communication diagnosis with the BCM fails. Could it be that the bootloader that wakes it up is corrupted? Does anyone know how to reprogram the software again? Has something similar happened to anyone?

La BCM es una DENSO TN232460



Thank you!!
