You need to fix this short first as it can give you false readings for other pinpoint test. You can run a new wire which is sometimes easier the then locating the bad section of harness.
Ok, I will try this. What I don't understand is how I can have the appropriate voltage at the actuator connector if there is a short in the wire; as well as how I can have a short in both the 249 and 250 circuits which are essentially the ground and the hot wire coming from the EATC. Makes me a little nervous to start cutting wires, but I will give it a try. I will get back to you when complete.
Just create a jumper for 249 to begin with.
