Diagnostic test points on the DPM have a voltage output range of -5…+5V.
Table 5
identifies test points on the DPM.
This table defines the states of LEDs D9 and D11 on the DPM board, which
uses D9 for the inverter side processor, and D11 for the rectifier side processor.
The other two LEDs (D6 and D7) are the watchdogs for the inverter and
rectifier code respectively.
