Tom,

I have an idea to make a special cable that will allow a laptop and a select monitor to be plugged in at the same time. Then we can see on the laptop screen exactly what commands the select monitor is sending to the car and what replies the ECU is sending back.

If I can build the cable and send it to you, would you be willing to give it a try with your select monitor? I just need to go to the Subaru breaker and get hold of three of the yellow female diagnostic connectors and one radio harness connector, then splice them together in the right way.

Phil.
