Hi guys. I am trying to use the Torque Pro App to read realtime Block Voltages on my 2005 Prius. For some reason the 1st block shows the usual 15+ volts but Block 2-14 show -330v ???? What is up with this?
I have the same problem! I'm wondering if it might be the cheap elm bluetooth device I bought on ebay. What type of obd2 reader are you using? Did you ever figure out a fix?
I think I've found the answer on another thread in PriusChat: Best OBD reader, Gen 2 prius? | PriusChat Looks like you don't get all of the toyota-specific codes unless your adapter supports J2534 standard. That thread has a recommendation for a Panlong bluetooth adapter. I was hoping I could buy it from the PriusChat store, but it looks like I'll have to go to amazon. Not as ridiculously cheap as the one I bought, but still very inexpensive...
I ended up going with a bluetooth adapter from BAFX, also recommended on that thread. It works great, and was about $20. Torque pro now gives me all the cell voltages, and I see that my HV battery is still in good shape.
