Hi all,
Managed to get another 4e0 unit but am a bit worried about plugging the thing in after the first unit didn't power up.
With the unit off the car can I simply apply 12v to pin 1 and ground to pin 2 and check the red light blinks on the MOST output first?
Also am I correct in thinking that pin 10 and pin 2 should have continuity as they are both off Terminal 31?
Lastly how does the diagnostic wire work? What sort of signal does it send to the Bluetooth unit or does the unit send a signal back. I'm sure when I was checking with a digital voltmeter between diagnostic wire and ground I was getting 12v. Is that correct?
Many thanks for all the help
Ben..
