OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
Society of Automotive Engineers standard SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world.
When it was introduced in 1987, the Series 60 was the first heavy-duty diesel engine with fully integrated electronic controls. [2] Detroit Diesel prescribed overhaul intervals of 500,000 miles (800,000 km), then raised that to 750,000 miles (1,210,000 km) after more experience was gained with the new engine.
Freightliner expects that the locomotive's efficiency is 7% higher than contemporary models, with a further 3% increase in efficiency whilst braking; regenerative braking is used to supply the energy to power auxiliary motors. [5] [6] The locomotives were given the Class 70 TOPS code. [7] [8]

The Freightliner Cascadia is a heavy-duty semi-trailer truck produced by Freightliner Trucks.The Freightliner Cascadia was designed with fuel efficiency in mind, as well as improving upon several other features including the powertrain offerings, sound mitigation, safety systems, and overall mechanical reliability from its predecessors.
The Freightliner FS-65 is a cowled school bus chassis (conventional style) that was manufactured by Freightliner from 1997 to 2008. Derived from the Freightliner FL-Series medium-duty trucks, the FS-65 was produced primarily for school bus applications, though commercial-use buses and cutaway-cab buses were also built using the FS-65 chassis.
The Series 92 engines were introduced in 1974. [8] Compared to the Series 71 engines they were derived from, the Series 92 featured a larger bore of 4.84025 ± 0.00125 in (122.942 ± 0.032 mm) and an identical stroke of 5 in (130 mm) for a nominal displacement per cylinder of 92 cu in (1,510 cc), from which the Series 92 derives its name.
The M915 has a 855 cu in (14.0 L) Cummins NTC 400 developing 400 hp (300 kW) at 2100rpm and 1,150 lbf⋅ft (1,559 N⋅m) of torque at 1500rpm. The M915A2 had a 775 cu in (12.7 L) Detroit Diesel Series 60 DDEC II developing 400 hp (300 kW) at 2100rpm and 1,400 lbf⋅ft (1,898 N⋅m) of torque at 1200rpm.
