ODB Plug has no power

Yesterday I finally got my ECMLink package. Was so exited.

Went out and just got no connection error. /ubbthreads/images/graemlins/frown.gif Should have known it was too easy.

Did some readings on the plug. pin 1 pulses as it should. pin 12 is ground but there is no voltage on pin 10.

So is there a fuse connected to that I can change?

If not, where can I draw power from?

I have a spare plug. if I want to install that 1 at the Ecu, what pin do I draw power from there?

Hope someone can help /ubbthreads/images/graemlins/smile.gif

You will have to back probe at the ECU to see if there is around 4.5V coming out of it.

You will need to measure voltage at pin 2 of the large connector (of the three ECU connectors).

See this chart
click

Edit, just saw that you live in denmark. I don't have wiring diagrams for their ECUs.

You seem to misunderstand. Pin 2 on the ecu is the diag port. thats = pin 1 on the ODB, that is working. Its the flat 4.5 volt on pin 10 of the odb plug thats not working. thats afaik NOT pin 2 on the ecu?

And its a US VR4 so.. /ubbthreads/images/graemlins/wink.gif

Edit: Hmm maybe I misunderstood :p

Plug ECU
pin1 pin1
pin10 pin2
pin12 ground

Is that correct?
