I received a wifi connector and noticed in the instructions that you have to put the car in diagnostic mode. I was trying to use my laptop to do E-Sys coding but not able to get the car to communicate with the laptop. I am using a connector with a Cat5 cable.
Does anyone know if you have to put the car in diag mode to get E-Sys to talk to the car properly? I have never had to do this before.
