I recently installed an edge monitoring system. My truck was giving me some signs that the FICM was needing replacing. However on my Edge monitor it shows that my FICM is running between 48 and 49 volts. How reliable is this? Has anyone had what the monitor say one thing but in actuality there voltage was signicantly lower? Thank you.
well it has a puff of greyish blue smoke when it starts in the morning. It also has an erratic start up. Sometimes it is Bang and it fires right up and the next it kind of grumbles to a start. I have no egr. Here are my codes.
