hello everyone. I have a 09 Tahoe hybrid and while I was driving the vehicle engine power disabled and it sounded like it went into hybrid mode but wouldn't move. I shut down the truck and restarted and it drove but super slow just enough for me to get into a parking lot and died. I got 8 error codes. P0016 p0106 p0068 p0ac4 p0ab9 and then repeated 0016 0106 0068. 12v battery didn't hold a charge and was dead so we replaced it but now dealership is saying I need entire hybrid battery pack. 214,000 km on it so it's not under warranty. Can I test individual modules to see if there are a couple bad modules and how would I do that because I can't afford the 5600 bucks they want.
