Toyota Prius 2007 (2ND Generation) Let's repair it together ABS VCS Brake RED TRIANGLE Engine Issues

I will go straight to the main point, don't expect from me to tell you or read the bible because your time and mine is Very Valuable.

scenario/Place where Prius started giving me issues: I bought the Pruis on January 7, 2020, with 156000 Miles and excellent cosmetic and mechanic conditions in an AUCTION. On February 2, 2020, the temperatures in Las Vegas reached 29F degrees during the night. The next day, I went to work and the car drove as normal as always. Lunch Time, I went to my Prius to take a nap and 3 minutes later the RED TRIANGLE, VCS, ABS, BRAKE, (( ! )), ENGINE LIGHTS CAME OUT. I turned the engine off and on, and the engine did not turn on, at all. People helped me to jump-start the car but did not work. After I watched YouTube for 4 hours, it says that I have to unplug a sensor or cable from the 12V battery located in the trunk, right side. after I waited for 30 seconds I plugged-in back again and BOOM the engine turned on. No Light came out, until 5 minutes of driving my Prius back home. I bought in Amazon Bafx Products Wireless WiFi OBD2 / OBDII Code, I was only able to remove temporary the lights mentioned above, and the Prius was able to drive with no problem. But every time that I was turning the engine on, I have to reset the codes again to drive the car.

Purpose: I will repair my 2007 Prius by myself + your experience advice, so in the future more Prius drivers can take advantage of this regular mechanic issue with the Prius.

1. Changed oil and filter, BRAND: Amsoil Signature Series 5W-30 Synthetic Motor (Bought it in the Amsoil Warehouse)
2. Optima Batteries 8171-767 (DS46B24R) YellowTop Prius Battery (O'Reilly Store))

Once I get home I will post all the codes that I got from the techstream software, also I found in my car a receipt of parts purchased before the Prius was sold to me..

Thank you SFO,

the Gallon of AMSOIL oil and filter + Membership for $10 buck for 6 months = ~ $67.00 and yes there are a big warehouse who distribute the product to the dealership who will charge you for the regular amsoil oil $97 or $110+, with the membership the oil cost you
$38.55 and filter 15.60. good price versus Amazon or any other location.

 

Hi TMR_JMA, to be honest, I remember I saw that code P0AA6, I am ready to start working with this repair. I only have Windows 10 and 8. my laptop used to be Windows 7 but Windows updated the whole system. every time that I drive the Prius, the battery seems to recharge very quickly, it takes less than five minutes to get recharge (Green Battery). But today I will start doing this. In case I need to replace a battery cell, which website do you recommend to buy parts of the Prius?

 

UPDATE: The Codes that I am getting are Hydrid COntrol - P0AA6/ 156 , ABS/VSC/TRAC C1259, C1310, C1345, Air Conditioning B1421
I already removed the HV Battery and I cleaned up the chain of corrosion BUS BAR (with Vinegar, Salt, and Baking Soda, bus bar looks newer again ), I tested each battery Cell and it got between 7.80 to 7.96 and driving got a score of ~7.6 each cell. so I don't believe the batteries' cell is bad. I put it back the HV battery and everything was working ok until the codes came out again and I cleared out the DTC codes and I drive the car with no problem, even the fuel gas consumption improved a lot, I turn the engine on and off and drive a few miles, lights never came out. Today I was coming from home to work and when I turned to the right side to enter tot he parking lot of my work site and less than a minute the RED TRIANGLE, TRAC, and VSC light came out again. That action looks like the same action that I did the first time when the warning lights came on the dashboard. Any advise?

Im sorry is 526 ONLY
and C1310/ 156 Only
I am using Techstream Toyota System 14.023.30., basically, when I click on the Data list, the code shows up on the system with all other Prius mechanism or sensors that you can test as well.

 

Once I get home I will post pictures and Data Freeze, Also I am got a feeling that the wheel sensors are the problem, based on what I have been reading and the way I drove the Prius and then the lights came out. but I will keep you post it about this issue today.

 

I just tested the car this is are the results...

 

From the bottom to the top, that's the way I inspected this HV Battery, I did not see anything looked like wet or leaked around the case, battery cell or cables, of course, I cleaned up the bus bars and look like a new bus bar. yesterday I tested the car and I cleared all the codes and then I drove 3 miles around my home. today in the morning, I turned the engine on and the ready mode showed up (weird, because usually, I have to clear out the codes if I want to drive the car) I've driven12 miles away from home and work and the red triangle, VSC, ABS, brake, Track lights haven't come out yet, but I know pretty soon it will come out lol any advise how can I start expecting once again the HV battery? Chapman mentioned used the megger, on Amazon, there are a lot of those, which will be best but cheap lol. Thank you, guys.
