Are you testing it on bench or in the vehicle?

Measure voltage on your 20 pin plug (terminals 19 & 20) and see what the voltage readings are when it is plugged in and plugged out.

Yes red and brown.
What voltage readings are you getting on these 2 wires when the plug is in the unit and out of the unit?

What voltage readings are you getting between red and brown wires when the plug is in the unit and out of the unit?
