3250 FMI 14 EPA10 fault summary
It ties the fault to excessive idle time and hydrocarbon build-up, verifies the ACM software level, screens for related codes and checks the turbocharger inlet for oil before a parked regeneration. Every step is laid out as a Yes/No decision branch, so you can follow the same path a Detroit dealer technician would without guessing.
- Verifying ACM software level (v8.5 or higher)
- Checking for SPN 3250 FMI 0 and FMI 8
- Reading the FMI 14 occurrence counter
- Inspecting the turbocharger inlet elbow and outlet pipe
- Parked regeneration to clear the code
