Check Engine + Light Triangle + TCS+ P0AFA P3000 On

Most of the more capable scantool apps in the review thread (such as the autel) will only work with their own proprietary devices (and vice versa).

If all you want is something for DrPrius, then you have to look at a "generic" OBD2 bluetooth device for your smartphone. Most are for android, a few are specifically iphone compatible.

It is a little difficult as the list on the DrPrius site is several years old and what's available now has changed. So some recommendations are outdated (the BAFX device that I have works fine but doesn't seem to be available anymore).

The OBDlink MX+ is a good device but it's pricey for "just" DrPrius. (the OBDlink app isn't very good compared to a more capable app like autel's).

You need to take a video of the Dr Prius app data when you are driving the car. The best is to do hard acceleration and maximum regenerative braking during the drive. Then, post the new video.

 

The second pair of modules has values lower than the neighboring pairs of modules.
With a difference of 0.3V, the ECU records an error on the battery.
You need to find out why the voltage in the second pair of modules is lower.

 

It appears that the problem is in block #2 of the battery. One or both of the modules in that block has a problem.

 

$1450 doesn't sound like enough for a new Toyota HV battery from a dealer (even over the counter - no labor). If the receipt wasn't from Toyota, then it would (have to?) be a "refurbished" (aka used) battery.

Usually a "good" refurb lasts 2-3 years. 5 years is a lot. 7 years is way lots. (Bad refurbs have problems in a few months or weeks).

Also, if you click the red button on the right of the Dr Prius screen, it will record a datalog to a .csv file.

The first thing you need to do when working with high voltage is to pull out the orange pin from the high-voltage battery. This will not prevent an accidental spark from a careless operation, but it will save your life.

If you ever had an electric flashlight with a long handle, into which three cylindrical batteries were inserted, then you may have noticed that the flashlight began to shine poorly and it was enough to change one of the three batteries so that it began to shine at full strength.

The same story with the high-voltage battery. As soon as a weak or discharged element appears in a set of 28 modules, the internal battery ECU signals this with an error, a code on the scanner or an icon on the dashboard.

That is, to restore the battery, there is a way to replace these modules with more charged ones. Where can I get new modules? From sellers and it is better if there is a guarantee.

The replacement itself is available to anyone if the rules are followed. There is a video on how to disassemble and assemble the battery.
But after assembling the battery, a situation may arise when the high-voltage battery does not work. You will have to diagnose again and find out which of the units is weak.

Some hybrid drivers buy not one module but a whole set of 28 modules at once. This allows you to forget about battery errors for a long time.
