 Ford Focus III - 20 2.5 No communitcation to ECU from OBD2 port - colinod
I may have had the pins for high and low put back in the wrong place and have read somewhere that ford have been known to reveres the colour of these cables on some cars

Is this possible

Currently have pin 6 grey with red stripe and pin 14 is blue

I had someone make up a OBD lead that swaps the pins around so then you have to swap the pins around in OBD port to match so port is useless unless you use the lead as i have key-less starts and lots of my type of car are being taken using port to clone keys.

We never checked the layout of pins before moving and am now thinking that the two CAN pins may have been reversed as i have read but i cannot find where i found that information now.

Just thinking that if i swap the pins around in the OBD port would that cause a problem to test?

Is there a difference in voltage on the two wires that i could check with multi meter?

thanks
