Gen 2 P0420 P0446 C1259 C1310 HV charging problem?

I later had charging problems with the rebuilt pack. I attribute this to having an older version of the HV ECU, which is on board the pack assembly.

I had the Denso part shown in on the Red label.

If you have such, just do some preventive maintenance and get the newer design, with the black label.

Since my post on Feb 4th, I have not read the wonderful comments by Panicos and Tombukt2 (is there a pun there? is he from "Timbucktu"?)

More soon.

Panicos - No, I did NOT follow that protocol. I used the guidelines found at

I had used the Hobby King charger, and went down to 1.2v for the MODULE. that's 0.2v per cell.

Now I use a Tenergy 180T, which can do 16 cells at once, so I can do the whole "block"-- 2 modules.
I can even leave the orange busbar in place.

Now, previously (#21), I said that I thought the black label was the newer technology. But upon checking the label, the red one says 89890-47092, while the black one is 89890-47090.

When I went to eBay, someone says that that ECU monitors voltage and temperature.

My symptoms right now are that it charges great, into the green bars, then suddenly drops into magenta. (!)
It is almost like there is a short.


I am not get very useful codes from Techstream, and I cannot seem to buy a bluetooth ODB2 unit that I use with my Dr Prius app. I had a Panlong, but it failed. I sent it back, and the 2nd one also failed. Lately I tried a brand from Amazon, but it says "socket closed".

Someone suggested a dongle that runs about $60 as being more reliable. I will have to get more data.

 

ChapmanF, thank you again. Your comments are esteemed by me, and I'll keep everyone posted.

Folks, there are a dozen or so members whose advice is just invaluable. ChapmanF is of this calibre, IMHO.
