EMU Black manual states to use “sensor ground” as ground input/reference for the digital SW inputs.
Is there any issues when using regular good chassies ground next to the needed switch?
I understand that there can be a possible ground potential difference to the sensor ground that might cause SW1-3 input false triggering and ideally correct way is grounding to sensor ground.
Theoretically how real is the problem when the vehicle has good and checked ground connections?
ECU grounds (PGND + ECU GND) are grounded to the engine and engine is grounded to chassis.
Any real possibility to distort the sensor readings that are connected to sensor ground while the SW1-3 is triggered when using regular chassis ground?
I’m asking because it is considerable amount of additional work/time bringing sensor ground wiring to the additional switches correctly/neatly that are now being added later after previously made ECU installation (all leftover inputs are brought near the switches before).
