Fixed the plugs to make it an easier task once I started. I taped it all up nicely as well so wires wouldn't be all over the place. I read up on the pdf file of the instructions and also followed the color coded wires to know where they were supposed to go. Taking it out of the donor car also helped me out as well. Well I went thru the functions of the obc and 1 option has me puzzled what it is. Option 4. It just has an "M" and a number. Don't know what it means though. My mpg is almost on point. I went for a drive and it was about the same read out as my mpg gauge on my cluster (mind you I have a swap and swapped in the cluster as well). Can anyone enlighten me what option 4 is please? Option 1: clock Attachment 15215 Option 2: temperature Attachment 15216 Option 3: MPG Attachment 15217 Option 4: unsure what this is?? Attachment 15218 Option 5: MPH Attachment 15219 |
Did you not get the "PPP" screen?
