Prius Plug In P1A00, P1A61, P1A64, P1A67, P301A, P314A, P31AB

Amazing not much info on the Plug In Lithium packs. I finally ran, and tried to run away from and, across one.

Throws the Prius Plug In P1A00, P1A61, P1A64, P1A67, P301A, P314A, P31AB and typical three ABS ECU codes I'm used to seeing with the other gens when the HV pack is having issues.

Appears the recall for the fuse was never performed to begin with. Not sure if related or not as I've not found a reference for what codes get triggered in the event fuse goes bad. Still reading into NHTSA info.

P314A is hopefully straight forward regarding a connection or the inverter pump needing swapped. Will see when get to if not more as per the Service Manual of which I've not read into in detail yet. Still researching online sources prior.

However, the rest of the codes found appear to be resolved per replacing the HV pack with a known good one per:

1. The titled "Hybrid Cell Voltage" thread. Hybrid Cell Voltage | PriusChat
2. The Youtube video comments by Best Car Fixes titled "Toyota Prius 2012 No Starting Diagnose Codes P1A64-P1A67 P31AB-P1A61 _ Step By step part 1"

Per the not exact same code Hybrid App video titled "Prius Plug-In battery error code P1A05, P1A0A, P1A63, P1A64, P1A67", appears there are issues with the BSU. Purchase a used or new "battery smart unit" AKA: BSU and "the glass unit" from trusted source, parts number 89892-47011

I am wondering if the 2016-2022 Gen 4 Lithium option pack that uses the same looking case as the NiMH hv pack case uses the same BSU since looks the same per this Weber Auto video titled "2016 - 2022 Toyota Prius Li-Ion Battery" at this time 31:48.

I am also wondering as well about cells interchange between 2012-2015, 2016-2022 gen 4 Li-Ion and 2016-2022 Prime HV packs. Anyone familiar with and know about options regarding?

Removing the 2012-2015 Plug In pack can be found here at the Youtube video by Fully Charged Zone titled "Prius Plug-In Hybrid Battery Removal 2012-2015"

Two other videos I found on Youtube for the 2012-2015 Plug In are regarding cleaning the fans:
1. Toyota Maintenance titled "2015 Toyota Prius Plug-in Important Maintenance"
2. Marshall Goldberg titled "Prius Plug in Cooling Fan Clean"

 

Hi @Jjacktheripper,

Thank you kindly, definitely helps for certain.

Confirmed the BSU's are close looking from a distance, so I am only just a little crazy and hopeful overly optimistic. 2012-2015 Plug In Prius followed by Gen 4 Li-Ion HV pack option shown below for the curious.


I saw two sellers on eBay noting "2012-2022 Toyota Prius Plug-In HV Hybrid Battery Cell Lithium 3.5V OEM" with photos of what looked like 2012-2015 Pip cells and that alone boosted my confidence of dreams of interchange. Especially seeing more cost effective Prime packs online, so ideally newer cells.

Reminds me I can use a full version or two on my other dedicated Dr. Prius smartphones. Next pension payment.
