2009 Cadillac Escalade Hybrid problems

Hi guys,

We have a 2009 Cadillac Escalade Hybrid that won't start up. The 12V battery is OK, the high voltage battery is also OK, but we can't make it start the engine up...

I've read in other GM forums that sometimes after problem that occurred some modules have to be relearned or something. So, my question is can I do something like this with the HP scanner? There is no GM dealer here in Bulgaria and we don't want to buy GM scanners for one car only...

The error codes that we have stored are:
P0C76-00 hybrid battery system high voltage
C0895 device voltage malfunction

Do you, guys, have any idea what we can do to start that thing up?:pray:
