As recognized leaders in world-class product support documentation and systems, O'Neil & Associates has expanded its core capabilities to include a team of recognized leaders in the creation and delivery of EMS (Electronic Maintenance System) IETMs (Interactive Electronic Technical Manuals) and intrusive diagnostics authoring. The team includes military platform maintenance experts with extensive experience in the development of Class V-authored applications (intrusive diagnostics), related software and peripheral hardware, training, technical services, product development, and future program activities for weapon systems equipped with IETMs.
EMS-2 IETMs are already developed for the following systems:
- High Mobility Multi-Purpose Wheeled Vehicle (HMMWV)
- Palletized Loading System (PLS)
- Heavy Expanded Mobility Tactical Truck (HEMTT)
- Heavy Equipment Transporter (HET)
- Family of Medium Tactical Vehicles (FMTV)
- Light Equipment Transporter (LET) M915, M916, M917
- Medium Tactical Vehicle Replacement (MTVR)
- M900 Series 5-Ton
- Field Artillery Ammunition Support Vehicle FAASV
- Armored Personnel Carrier (APC) M113A3
- Hercules (M88)
- Stryker
- LHS Compatible Water Tank Rack HIPPO
O'Neil offers value-added qualities that set us apart from the competition:
- Subject Matter Expert (SME) authors have unparalleled expertise with regard to mechanical and electrical military systems maintenance and vehicle data bus communication.
- Extensive knowledge of military vehicle test equipment and peripheral hardware and software.
- Coordinated working relationships and communication with suppliers of peripheral hardware and software equipment, including U.S. Army, PM-TMDE (Test Measurement and Diagnostic Equipment), and ARDEC.
Vehicle subsystems that have been authored using EMS intrusive diagnostics for SAE J1708/1587, J1850, J1939, MIL-M-1553, RS-232, and DCA include:
- Engines
- Caterpillar C3126A, C-3126B, C7, and C-12
- Detroit Diesel DDECII, DDECIII, DDECIV
- Transmissions
- ATECI, ATECII
- WTEC III
- GM4L80E
- Antilock Brake System (ABS)
- Eaton
- WABCO
- HALDEX
- Central Tire Inflation System (CTIS)

The U.S. Army Electronic Maintenance System (EMS) Interactive Electronic Technical Manual (IETM) and associated vehicle computer displays with point-to-point wiring and signal tracing significantly improves operational readiness and reduces the total cost of ownership of U.S. Army tactical and combat war-fighting vehicles.
The real-world application of EMS reduces the No Evidence of Failure (NEOF) and Mean Time To Repair (MTTR) for globally fielded systems. It provides a unique "intrusive diagnostics" design approach that distinguishes it from other classes of IETMs. EMS provides real-time interaction between the system and the user/maintainer by sending and acquiring data from embedded sensors and data busses.
The malfunctions and associated repair information are quickly displayed, accelerating the troubleshooting and repair process. Taking maintenance to the next level, EMS enables maintenance prognostics by collecting maintenance data for transmission into a Predictive Maintenance Module (PMM) via a Global Combat Support System. Additionally, online instructional videos are provided to guide the technician through diagnostic troubleshooting and repair procedures to automated parts ordering.
The EMS IETM is a portable maintenance expert, containing a comprehensive, easily updated database. Extensive user testing has proven its effectiveness in the field and at the maintenance depot. The EMS IETM uses a comprehensive authoring environment to populate, manage, integrate, and communicate with the vehicle systems and logistics personnel.
EMS runs on a Microsoft Windows-based portable computer with hardware interfaces that connect to the vehicle/aircraft/ship for quick, interactive diagnosis. EMS provides the technician with the ability to correctly conduct real-time, comprehensive maintenance at all levels.
- The PC connection to the vehicle enables EMS to access the vehicle or aircraft's electronic built-in test information.
- The data is instantaneously passed to EMS for analysis.
- EMS begins diagnosing the problem by automatically taking electronic measurements or providing the technician with measurement instructions. Based on the results, the system determines the next diagnostic step.
- If no fault is detected, the technician can enter a symptom from a master list to begin troubleshooting.
- Once the real problem is isolated, EMS accurately accesses the appropriate place in the online IETM to begin troubleshooting.
- EMS guides the technician through repair procedures with text, graphics, audio instruction, and video clips. Required replacement parts are displayed with National Stock Number (NSN) and necessary electronic ordering information.
- A history of tests, adjustments, results, and procedures is automatically recorded.
- EMS can be used off-vehicle to provide training in the field or classroom.
EMS significantly improves field operation on systems by providing:
- Rapid Turnaround
- Reducing time spent seeking and retrieving maintenance information
- Reducing No Evidence Of Failure (NEOF) and Mean Time To Repair (MTTR)
- Improving troubleshooting with the EMS built-in knowledge model
- High Quality, Low Price
- Replacing more expensive processes that are far less effective at diagnosing and solving real-time, unit level maintenance problems
- Replacing traditional methods of electronic troubleshooting that require significant logistical support
- Better Performance, Fewer Errors
- Reducing the need for highly skilled technicians to support the system
- Significantly reducing repair and supply costs by greatly improving the probability of finding and fixing the real (rather than the perceived) problem
- Verifying that the repair fixed the problem
