Haunted by the Red Triangle

Which modules did you replace?

Did you balance the modules you put in along with all of the other modules?

Just swapping out modules doesn’t give a lasting fix .

Reconditioning and balancing does.

Good luck and keep us posted .

 

Battery temps seem really high. Are you sure your fan is working?

 

Block 12 is about 1.3 volts lower than the average of the others (post 3...at idle in driveway). One of the modules in block 12 has a bad cell.

Easy Squeezy...replace the bad module in Block 12. There's some other issues with your modules that may need to be resolved later, but that should at least get you running again and give you time to make a long term plan.

 

Call me strange, but I would first want to know which codes are setting, and which of the three icons in the touchscreen are lit up.

 

ok, You're strange...………..

 

It wouldn't surprise me if Dr. Prius and Torque Pro haven't been fully checked out on 2001 Prius. If you really want the best diagnostic data, you'll have to use Techstream.

But module 12 has a problem. A module that is 1.2 volts or more less than the others has a defective cell in it.

 

Or, IDK, if he's not actually connected a meter to the cell to confirm, it may have a defective harness or ECU?

 

No, Strange. Block 12 has a bad module. All that's needed to confirm that is the graphs he provided. Under load it goes lower than the others. Under charge it is going higher than the others. On the low side, it's right at 1.3 volts down, which is conveniently the voltage difference caused when 1 of the 6 internal cells fails inside a module. All are classic signs. There could easily be other issues to go along with it, tho. I'm sure there are other weak modules that will pop up.
