What is the fix for P3449 code?
I have been getting this code for over a year. One of the first
things I noticed failing on my Aspen was that it would not
remain on if I used the key(button) to start my aspen from a
far. Soon after the CEL came on. I finally took it to the auto
shop (not dealer) this month and received a diagnosis to
replace all 4 MDS. So i did. But with my own mechanic. The
scanner reads the code, erases it, but code is right back on
after we start the truck. The truck also does not remain on
if i start the truck with the button on my key...i was hoping it
did. Ive read about replacing the ignition coil to #7 and by
the sound of this thread, ECM may be next. Can anyone
relate? Any feedback would be appreciated.
