Default prius won't start.

so my 2004 prius has been through quite a bit lately. a few months ago I hit a car and bent up my fender and a little bit of the hood and bumper on the drivers side. aside from the cosmetic damage I don't think it did any significant damage. had a small tree fall on the back hatch and destroy the window in a storm, usaa covered the repairs. when i got it back the 12v battery finally died so I replaced it. then 2 days ago i drove it maybe 40 miles out of town and the triangle with the exclamation mark poped up on the dash and "problem" and a red box with an exclamation in it came up on the top left corner of the display. the next day driving home it disappeared half way home. now this morning I tried to start it to take it to the shop and instead of powering on to ready it flashes 5 boxes over the drive, neutral, park, ect. the battery gauge on the display is completely empty so I tried giving it a jump like when the 12v battery was dying before but it didn't help. I borrowed one of the obd scanners from autozone and it gave me a U0293 code. tried disconnecting the 12v battery for 5 minutes but it didn't change anything. I was considering replacing the inverter pump or picking up a usb can-bus adapter to get more details. Any ideas as to what might be wrong?

Default Re: prius won't start.

The battery ECU receives signals from the HV control ECU, ECM, and gateway ECU via CAN (Controller Area Network) communication.

The Controller Area Network (CAN) is a serial data communication system for real-time application. It is a multiplex communication system designed for on-vehicle use that provides a superior communication speed of 500 kbps and a capability to detect malfunction. Through the combination of the CANH and CANL bus lines, the CAN is able to maintain communication based on differential voltage.
• Malfunction in the CAN bus (communication line) can be checked through the DLC3 connector, except in case of an open circuit in the DLC3 sub bus line.
• DTCs pertaining to CAN communication can be accessed through the use of the intelligent tester II (with CAN extension module).
• Malfunction in the DLC3 sub bus line cannot be detected through CAN communication, even though the DLC3 connector is connected to CAN communication.
