Vehicle Make, Model, And Year
The code U1111-1206-8250 maps to a 2016 Nissan Rogue Sport (known as the Qashqai in some markets). Nissan uses this internal part-numbering scheme for wiring harnesses, control modules, and calibration files, so the string identifies the exact vehicle configuration the module was built for.
Production of the Rogue Sport began in 2017 as a smaller companion to the full-size Rogue, but the 2016 calibration files were created during the pre-production validation phase. These files are sometimes flashed into early-build vehicles or service-replacement modules, which is why the 2016 date appears in the identifier.
| Model Year | Market | Engine Options | Transmission Choices |
|---|---|---|---|
| 2016 (pre-production) | North America, Europe | MR20DD 2.0L I4 | Xtronic CVT |
| 2017 – 2023 | North America | MR20DD 2.0L I4 | Xtronic CVT |
| 2017 – 2022 | Europe, Japan, Australia | MR20DD 2.0L I4, R9M 1.6L diesel | 6-speed manual, Xtronic CVT |
“The 2016 calibration identifier is a red herring. Nissan’s pre-production modules were stamped with the planned model year, but the actual hardware was identical to the 2017 production units. If you’re replacing a module, match the part number on the label – not the year in the software string.”
– Nissan Master Technician, Nissan Technical Bulletin NTB18-045
Vehicles equipped with this calibration file will also carry Nissan’s VIN prefix “3N1” for North American models or “SJN” for European and Japanese markets. The 8th character of the VIN decodes to “C” for the 2.0L gasoline engine, confirming the powertrain match.
