Hybrid battery overcharging after ABS issue

Full charge in Prius OEM is ~80% You got nothing to worry about, especially with NiMH electrolyte, even at 101% charge levels!

 

It is not 100% fully charged. To reiterate what PriusCamper said in post #2, The graphic on the Energy Monitor screen only displays the 40% (the bottom purple bar) to 80% (the top green bar) range of the battery.

You should also understand that when the top bar lights, it does not mean your battery at 80% charge as this will light when the SoC is 75% and continue to accept charge until it reaches 80%. Furthermore, the second bar has an approximate range of 64% to 77%. From this you can see that the battery can never reach 100% from in-car charging.

The change in behavior you describe is typical after the battery has been reconditioned, or sometimes after the 12 V battery has been disconnected (or gone flat). If that has not happened, I'm not sure what could explain the change in behavior. In any case, it is nothing to worry about, as Camper said.

 

Because "reset the ABS system" is not a thing, a post like this is a lot more useful if you link exactly what "online hack" you found that made you think it was—that way, other people reading have the best chance of knowing what you actually did.

 

If the OP can read the pack voltages with Techstream or some OBD2 dongle that might (but probably won't) show something interesting.

If the sense voltages stick at 16V or higher, in normal driving on a flat surface, that would indicate that the car is charging the NiMH pretty much all the time. But if that was the case the display on the MFD should also show arrows directed into the pack, possibly even when accelerating with all green bars, which really shouldn't ever happen. Normally any acceleration on a flat surface will have the arrows moving away from the pack, with the exception of when the pack is nearly depleted, in which case the car may charge the pack even when though the driver is calling for it to accelerate.

But I'm getting ahead of the data, which in all likelihood will be unremarkable.

 

This is also the method you use to read the blink codes... As in count the cycle of short blinks and long blinks and that count points to the problem your brake system is having. This "hack" is the last step in the process after you get your blink codes and you clear the error codes, but it doesn't prevent the error codes from coming back soon as the computers/sensors notice it again.

 

Depending on the error codes certain systems may be disable until the error codes are cleared. Eventually they'll come back. As for the jumping the pins "hack" and pushing brake pedal 8 times to clear codes after getting blink codes that's standard across most car designs: Blink (a/k/a Flash) Codes – How to. | PriusChat

 

Oh yeah, that "hack". That's a code clear; just makes the brake/skid ECU forget what brake issue(s) it was trying to tell you about, and also forget what fail-safe measures it might have been taking because of them. This is not guaranteed to make the braking safer than it was before you did it.

I see PriusCamper has pretty well covered that already. But other people do now and then come to PriusChat and read old threads, so this is worth emphasizing:

If you're reading this thread and thinking about trying this "hack" to reset a brake issue, please start by reading this page:

Blink (a/k/a Flash) Codes – How to. | PriusChat

and be sure to scroll down to the "About clearing codes" part.

 

When the time is right let whoever buys it know about this PriusChat thread and we'll do our best to help them out.

 

It wouldn't hurt if some of those other internet resources out there that keep sending people here thinking there's a "reset hack" (and probably sending other people with other cars to other car forums the same way) could have comments added—maybe even linking to the "about clearing codes" section on our wiki page.

I can't easily go comment on that youtube video myself 'cause I don't have a youtube account. (I started creating one some years ago but got a few pages into reading their terms and conditions and said 'Nope.') But somebody who does have a login there could.

 

Clearly you don't understand the social media nightmare we're living in. It's not based on what's most honest and most accurate, but on what gets people to spontaneously click even if they don't watch all of it or even have a problem with there car.

For example, let's say we did A/B testing and we got:

A: How a paperclip can allow you to count blinking lights to find out your car's error codes so you can read up on how to fix it.

B: This easy hack with a paperclip will fix your car's brake problems.

GUESS WHICH OF THESE TWO OPTIONS WILL GET THE MOST CLICKS?

 

Or maybe I do understand the social media nightmare, but still imagine complete defeat doesn't actually come unless everybody gives up and acquiesces.
