SPN 4360 FMI 15 is the Detroit Diesel diagnostic trouble code set when the SCR inlet temperature reads high on DD Series (EPA 2007-current) engines. This 1-page troubleshooting sheet lists the fault definition, the relevant monitor or note data, and a numbered diagnostic routine that ends in the correct wiring or component repair. It is drawn from TruckFaultCodes.com (© 2017) and applies to the GHG14 emissions calibration.

SPN 4360 FMI 15 table of contents
The technician first rules out SPN 3246/FMI 15 (DPF outlet over-temperature), which takes priority. Parameter AS095 SCR inlet temperature voltage is then monitored while flexing the harness to catch sudden voltage changes that betray a wiring fault. If none appear, the SCR inlet temperature sensor is disconnected, its connector inspected for pin damage, and the sensor replaced if the pins are sound.

Applicable truck models
This sheet is part of the DD Series diagnostic trouble code library and addresses the SCR inlet exhaust temperature circuit. The SPN 4360 FMI 15 procedure applies to Detroit DD Series (EPA 2007-current) engines running the GHG14 calibration, and the same code index is cross-referenced under the Detroit Series 60 (DDEC VI, EPA 2007) fault-code set. For engine identification and warranty details, see the Detroit Diesel official site.
Who needs this 4360 FMI 15 manual
It is aimed at technicians separating a genuine over-temperature reading from a wiring fault on the SCR inlet sensor of Detroit DD Series trucks. Monitoring the live AS095 voltage while flexing the harness is the key step for finding intermittents.
