What this fault code covers
The reference confirms the code as the Top 2 Shift Solenoid circuit showing an open circuit on pin 8 of the CPC4 #3 connector. It carries the standard advisory that the Common Powertrain Controller (CPC4) digital outputs share the same SPN as some Motor Control Module (MCM2.1) faults, and that the diesel diagnostic tool separates the MCM2.1 from the CPC4 when diagnosing. For wiring detail it refers the technician to Original Equipment Manufacturer (OEM) literature.
Applicable Detroit truck models
This page applies to Detroit DD Series (EPA 2007-Current) engines, and, where the fault is shared across platforms, Series 60 (DDEC VI – EPA 2007) engines. The same pin and connector references hold across engines built around the CPC4 and MCM2.1 architecture. Confirm the wiring layout against the manufacturer’s own documentation before opening the harness; official engine information is published by Detroit (Demand Detroit).
Who needs this SPN 702 FMI 5 manual
Fleet technicians, mobile diesel mechanics and workshop owners diagnosing a lit dashboard warning or a logged Top 2 Shift Solenoid code on a Detroit engine will use this sheet to confirm the circuit, pin and connector before touching the wiring, and to decide whether the CPC4 or MCM2.1 raised the fault.
