I'm wondering if anyone has any info on 03 Cummins ECM issues.
My son's truck has them.
It has already ruined the SD card with all the custom tunes, and we don't have a backup because it was installed on the truck when we bought it.
The ECM has been refreshed several times, and our research says this was a common issue.
My question is if anyone has information on how to correct it or if anyone has experience with it.
