My only suggestion is to test 12V. As it provides power supply to many electronics, so if 12V goes low, a lot may act up. Please.
Otherwise, no one can really remotely pinpoint what is wrong. Toyota uses Techstream as software that goes into the car guts to scope it. So dealership or good independent with that software and access to proprietary codes. As some things are released to dealership only.
12V you could test roughly at any parts store, just tell them it's deep cycle battery.

The battery was changed today, so this is occurring post 12v swap.

Ah huh.... Then the only way is to scope. Did it throw warning lights immediately after 12V swap? If yes, Toyota says to do 3 consecutive complete Start up/Shut down procedures. This si supposed to reset the system.

Yep, tried that, but it did not work either I am wondering if it could be a fuse or something . I am terrified of dealerships I have my daughters wedding in two months, a tax liability to pay so I really can't afford to pay the super marked up prices of Toyota dealership right now. Thanks for taking a stab at it though.

Well, USB to OBD2 port cable is $35 online and Techstream is free. Several owners here very successfully use that approach on their cars. Even a basic OBD2 scanner may reveal error codes.
I doubt it's a fuse. May need simple system reboot, which I believe is $90 or so at dealership (please, refrain from using derogatory term.) when they re-flash system with proper year software.

"P0A80" Replace Hybrid Battery Pack.

INSPECTION PROCEDURE


PROCEDURE

  1. CHECK FOR DTCS (DTC P0A1F-123 IS OUTPUT)
(a) Connect the intelligent tester to the DLC3. (b) Turn the power switch on (IG). (c) Select the following menu items: DIAGNOSIS / OBD/MOBD / HV ECU / DTC INFO / CURRENT CODES. (d) Check if DTCs are output.
Result:
DTC P0A1F-123 is output.
YES -- GO TO INSPECTION PROCEDURE RELEVANT TO OUTPUT DTC
NO -- Continue to next step.
  1. READ VALUE ON INTELLIGENT TESTER
(a) Ensure the safety of the areas in front and at the back of the vehicle. (b) Connect the intelligent tester to the DLC3. (c) Turn the power switch on (READY). (d) Select the following menu items: DIAGNOSIS / OBD/MOBD / HV ECU / DATA LIST / V1 to V17 BATT BLOCK. (e) Fully warm up the engine and turn the air conditioning off. (f) Firmly depress the brake pedal with your left foot. (g) Move the shift lever to the D position. (h) Record each battery block voltage from the data list (V1 to V17 BATT BLOCK) while fully depressing the accelerator pedal. (i) Compare the battery block voltages (V1 to V17 BATT BLOCK) between the even and odd number groups in each combination shown in the table below.

(j)
Check the voltage difference in the all 9 combinations.
OK:
The difference in voltage of all combinations is 0.3 V or more.
YES -- REPLACE BATTERY SMART UNIT
NO -- REPLACE HV BATTERY


This should be done with intelligent scanner. Like techstream.

Smile 2012 Camry Hybrid LE Check Hybrid System

Tuned off high-beam stayed on after car off and locked. caution triangle warning light stayed on when driving, ended up not starting, after sever battery drainage. CHECK HYBRID SYSTEM MAINTENANCE REQUIRED Came up when trying to start. Research has shown me this has been a problem for this year and car. Have to go to DEALER for diagnostic😞 Experience would be helpful
Update; Saturday 04/22/2017 Dealership just called, said a rodent chewed through to camshaft censer, they will repair and replace pins for $ 110.00 total. I'm happy it wasn't as bad as I thought.

That's about $4000 worth of relief!

Welcome to TN.
Did you disconnect 12V battery during removal?
To answer your question, Body Control Module totally knows seats were removed. This car has many computers that talk to each other. So it's plausible.
