    Congratulations on the scanner! Have you got your techinfo.toyota.com subscription yet so you can see the service manuals and look up what those codes mean and how to work them up?

    Cheers,

    DTC U0100 is the main code to figure out. This means there is a communications problem between the engine ECU and the hybrid vehicle ECU. Those ECUs are mounted right next to each other, behind the glove compartment. I suggest you remove the lower glove compartment so you can inspect the wiring harness that connects to the two ECUs, looking for obvious damage.

    If you see obvious damage then repair it. If you don't see a problem then you'll need to inspect the wiring more carefully. Subscribe to techinfo.toyota.com to obtain specific instructions about the terminals which provide power and communications - those need to be inspected for corrosion, etc. If you have an oscilloscope then you can look at the waveforms for the CANH and CANL terminals, which should be digital pulses.

    Same can line is connected to the battery ecu as well. Damaging the wires going to battery ecu seems to be way more realistic in rear end collision that this car had if I remember correctly. Problem in can line anywhere could create problem everywhere since its only one line.

    If these lines were damaged would it still be possible to ready up occasionally and have the car move? But by all means I will disable the HV battery and check the under body channel for wire damage.

    also what manuals should I get from techinfo.toyota.com for the codes etc. I don't see a good overall repair manual.

    Hope you don't mind if I link to an earlier post that already covered how the manual is organized. That post was for the Gen 1, which had two main volumes (plus wiring, NCFM, and body); in later generations the number of main volumes may have increased, without changing the overall organization as far as I know (diagnostic info in Volume 1, etc.).

    The only one that might not be of use to you is the body repair manual, which is for hardcore sheet metal wranglers and covers the kinds of repairs you use grinders and welders for. (All the repairs you can do with wrenches and screwdrivers are in the main manual volumes.)

    The New Car Features Manual is solid gold, because it's the one that tells you the whats, hows, and whys of all the stuff the other volumes try to tell you how to diagnose and fix.
