Trying to read current from the PDP

[franktate]

We're having a similar problem with three separate PDPs, all with firmware version 1.37. Even the RoboRIO web page Self Test for the PDP only shows all zeroes for all 16 channels. At firmware version 1.30, we were seeing values between 1 and 2 on all channels (even those with no breakers installed), but now it's just zeroes. Does anyone have any ideas?

I've tried connecting the PDP CAN directly to the RoboRIO, or with the PCM in between them, with the terminating resistor in the ON and OFF positions, and nothing seems to make a difference.

Additionally, on the PDP Self Test screen from the RoboRIO web page, the voltage seems to just go between 11.85 and 11.89 volts, with the temperature mainly jumping between 21.97 and 23.01.
