Urgent help needed.
I have lost serial communication on OBD. Have tried my Openport cable and a diagnostic tool with no success on OBD. No Ecu´s are available.
The car runs fine though.
I think i have damaged the Communication gateway when I had my laptop connected to the car and disconnected the battery.
Could it be a blown fuse somewhere'?
A schematic on the MUT serial OBD circuit would be a great help.
my car is a Evo 7 JDM
Thank´s , Lars
