hello, i'm having a difficult time understanding how to setup ground switched inputs. my ecu only sends ground outputs for my fuel pump and my electric fan. i currently have them setup as active low with the threshold voltage set to .1. i also tried setting it up with the recommended 4v, my output side is setup like this: Input 7 (fuel pump) status equals true
i'm probably missing something obvious but i havnt been able to figure it out. thanks
Just a little note to this i've found sometimes but not always that when using the DTA T series ECU the zero volt out puts (from the ecu) for the fan and fuel pump can fluctuate between 0 and 0.7 volts which if you set the trigger volts at 0.1 causes the PDM to think that there is no request from the ECU to run either.
