The Detroit SPN 713 FMI 7 fault sheet is a single-page DTC reference that identifies a top2 shift failure condition on the DD Series (EPA 2007-Current) powertrain. It describes the open, short to ground, or short to power on pin 7 of the CPC #3 connector, names the controller connector involved, and explains how the DDDL 7.X tells powertrain-controller outputs apart from engine-controller faults that carry the same code.

Applicable truck models and engines
This reference applies to Detroit DD Series (EPA 2007-Current) engine platforms fitted with the Common Powertrain Controller, and the code is catalogued for both current DD Series and Series 60 (DDEC VI, EPA 2007) installations. Because harness routing varies by chassis, always confirm pin assignments against the Original Equipment Manufacturer (OEM) schematic before testing. For engine and emissions-system references, see Detroit’s official powertrain resources.
Who needs this SPN 713 FMI 7 manual
This sheet is written for heavy-duty truck technicians and independent workshop owners who pull the code on a Detroit-powered unit and want a fast, accurate description of the failing circuit before they open the wiring harness or condemn a part.
Troubleshooting the SPN 713 FMI 7 fault
The document notes that CPC digital outputs share the same SPN as some MCM faults, so use the DDDL 7.X to confirm whether the code originates in the powertrain controller or the engine controller. Once confirmed, repair the open, short to ground, or short to power on pin 7 of the CPC #3 connector and verify the CPC #3 connector terminals, referring to the OEM wiring schematic for pin routing and expected values.
