Applicable truck models
Detroit DD Series engines (DD13, DD15 and DD16) from EPA 2007-Current, with equivalent coverage noted for Series 60 (DDEC VI) applications. Fault code SPN 191 / FMI 9 is diagnosed with a diesel diagnostic tool such as DDDL or DDRS. For factory procedures and the latest module software, see the Detroit Diesel official website.
Diagnostic steps and checks
A note warns that this fault sets during Eaton transmission module reprogramming and can be cleared and released if it occurs while programming. Otherwise the technician checks for CPC SPN 168/FMI 0/14/18 battery-voltage codes and MCM SPN 625/FMI 9, repairing those or the Controller Area Network line first, then asks whether the CPC was reprogrammed; if not, ServiceLink lists the configured modules and their communication status for module-specific troubleshooting of the affected controller.
Who needs this Detroit J1939 ETC1 message manual
This troubleshooting sheet suits Detroit-certified technicians and independent heavy-duty workshops that read SPN 191/FMI 9 on a scan tool and want the factory decision tree, pin references and component checks before replacing parts.
