SPN 714 FMI 5 is the Detroit DD Series diagnostic sheet that explains vehicle power shutdown open circuit on GHG14 engines. This code flags a vehicle power shutdown caused by an open circuit on pin 10 of the Common Powertrain Controller (CPC4) #4 connector. Detroit notes CPC4 digital outputs share an SPN with certain Motor Control Module (MCM2.1) faults, so the diesel diagnostic tool makes the distinction between the MCM2.1 and the CPC4 when it reads the code. Wiring schematic detail is taken from the OEM literature. This DiagTechPro library page outlines what the 1 page PDF contains before you download it.

Applicable truck models and engines
This fault sheet applies to Detroit DD Series engines built to the GHG14 emissions platform. It is used with the Detroit diesel diagnostic tool, and with ServiceLink where module configuration must be confirmed. Detroit publishes these fault codes through TruckFaultCodes.com, and the same SPN can appear on more than one module, so confirm the reading before ordering parts. For engine coverage and official service literature, see the Detroit official support site.
Who needs the SPN 714 FMI 5 sheet
Fleet technicians and Detroit-certified workshops troubleshooting this CPC4 digital output fault need this sheet to follow the correct checks instead of guessing at parts. It suits technicians confirming the reading belongs to the CPC4 output before tracing the open on the pin 10 circuit.
