Clicking from HV batter area when attempting "ready"

Thanks for the info Chap, informative as always. Agree re NiMH SoC. The point where these batteries do the rapid drop is ~192 V (1.14 V per cell/6.8 V per module). From my graphing of the voltage behaviour while discharging it is reasonably linear above this until ~220 V (1.31 V/7.86 V per module).

 

Oh hi again! Anything changed with your issue in the last couple months?

At the time of that post, it was looking like another choice of scan tool might be in order, to get status from the HV ECU.

 

That adapter should be fine, which 'app' are you using, some will use Hybrid Assistant, Torque, or Dr Prius. There are others Apps as well.
