Fault Code Taxonomy — SAE J1939 / OBD-II Mapping

PHASE I DELIVERABLE

Phase I deliverable: extend KYR's 12,196-code OBD-II taxonomy to Army J1939 platform codes.

J1939 SPN	J1939 FMI	Description	OBD-II Equivalent	Platform
SPN 91	FMI 4	Throttle Position Sensor Low	P0122	LMTV/FMTV
SPN 100	FMI 1	Engine Oil Pressure Low	P0520	HMMWV/LMTV/FMTV
SPN 110	FMI 0	Engine Coolant Temp High	P0217	All platforms
SPN 190	FMI 0	Engine Speed High	P0219	All platforms
SPN 3563	FMI 18	DPF Differential Pressure	P242F	LMTV/FMTV
SPN 5298	FMI 18	DEF Level Low	P203F	LMTV/FMTV

J1939 SPN (Suspect Parameter Number) and FMI (Failure Mode Identifier) are the military equivalent of civilian OBD-II DTC codes. Phase I maps overlapping fault categories across both taxonomies.

Prognostic Health Model — Vehicle A-03

FAILURE PROBABILITY FORECAST — 30/60/90 DAY

Model basis: 1,171 documented failure patterns cross-referenced against vehicle mileage and maintenance history.

Component	30-Day	60-Day	90-Day	Basis
Air Brake Seal Assembly	12%	34%	67%	847 pattern matches
DPF / SCR Assembly	8%	19%	41%	Mileage + fault history
Engine Oil System	73%	89%	95%	OVERDUE — immediate action
Fuel Filter	5%	22%	38%	Approaching interval
Coolant System	3%	11%	28%	No recent fault history

Phase I research will validate these probabilistic models against government-furnished 5988-E maintenance records under the research agreement.
