    So we recently replaced a engine that decided to make a rod salad in the oil pan. Car runs beautifully now except it has recently decided to flash a battery main symbol. And the battery display goes completely charged. We did run a reader and got for HV Battery: P0A80, P3013, P3019 and for Hybrid Control: P3000 and ABS/VSC/Traction Control: C1310 and C1259. Can anyone explain what we're looking at here

    Generally you're looking at a hybrid battery that's starting to fail

    How many months did the car sit before the engine was replaced and running beautifully?

    3-4 months. The original engine blew up at the end of April. The first replacement was installed mid June but when we ran it we found out it was a dud with a misfire and a rod knock. So we warrantied that one and got the second replacement and that was installed early to mid July. It was run in park and driven and seems to be acting normal other than a little overheating, which we know the issue there. But this battery main light is a new development.

    If you have an OBD2 reader you can clear these error codes and keep driving... Dr. Prius app is a good one for this. You can also use it to monitor battery temperature so you don't keep clearing codes on a pack that's starting to overheat.

    I would wonder if the HV battery is am "old" reman assembly. Sitting and not getting used is tough on old batteries, but having 2 blocks go south at the same time?

    P0A80 is "replace the HV battery", P3013 and P3019 are "battery blocks 3 & 9 are weak". P3000 - "go look in the HV battery ecu for codes". The other 2 ABS codes are "something's wrong with the hybrid drive system- PS, you have no regen braking".

    If you have a scantool or app (Dr Prius + a compatible OBD2 bluetooth adapter) then you can confirm wonky battery block voltages. When a cell fails in a module, the voltage for that block will usually be lower than the others by 1.0-1.5V when under load (moderate to heavy accel).
