Hey all, My 1012 Prius developed a P0A80 code some months back. After playing whack-a-mole a few times with my older Prius' modules years ago, I decided to purchase the NexPower lithium pack for this one. After driving it a few months in this condition, I'm finally getting around to installing the new pack, but have noticed a potential secondary issue: the SOC appears to be always at 6 bars. The "check hybrid system" dialog is always on display, but every time I hit the display button to bring up the SOC, it's always the same: 6 bars, no more, no less. As I understand it, a failing pack causes the SOC to swing wildly. Is a constant SOC indicative of another undiagnosed issue?
If you still have time to edit your thread title to change the "PA080" to the correct P0A80, more people may be likely to find your thread. (One quick check that a trouble code has been spelled right: the second character is never anything but 0, 1, 2, or 3.) It may be pretty common to see SoC swinging around on a tired old battery, but that's not exactly what the ECU is looking for to make the P0A80 judgment, so it probably doesn't need to be overthought.
i have the similar issue on 2012 camry i checked with obd app and it shows the small "aux battery voltage as -24" and also the HV battery "chg ctrl -24kW" and it also shows "battery block number with max voltage: Latest value 1" (but flickers from 1 to 17 ) "battery block number with min voltage : Latest value 10 " (steady) i checked the battery with multimeter and it shows around 12v anyone have any idea what might be the issue ?
Bisco, because I'm driving it while it's throwing the code, the "check hybrid system" dialog is obscuring the SOC. So I need to hit the display button on the steerimg wheel to see my normal display info In a few seconds, it reverts to the trouble dialog. So, I can't really see changes in real time (though clearing the code would get me by for a while). But SOC never changes from 6 bars when I do check it.
Brian, it's got about 227k miles on it. I'd been expecting a traction battery failure, as my 2006 Prius ran into this issue at about 185k.
