FCA or Fiat Chrysler Automobiles, has announced that it has formally filed an application for diesel emission certification with the US’s Environmental Protection Agency (EPA) and California Air Resources Board (CARB) for its emission software calibrations. Vehicles like the Jeep Grand Cherokee and Ram 1500 will feature such a system, which will govern emissions of the various diesel engines. This is an attempt by FCA to clarify issues related to the company’s emissions control technology that are incorporated in its software.

FCA is trying to avoid the diesel gate scandal that has plagued Volkswagen these past few years by coming clean regarding it’s software’s inner workings and the resultant emissions from the diesel engines that use it. The company says that by doing this, it should put to rest the EPA’s concerns regarding the hotly discussed topic of emissions software.

Besides the new vehicles, FCA plans on installing said software in 2014-2016 model year Jeep Grand Cherokee and Ram 1500 diesel variants, provided that it receives the green light from the EPA and CARB. Owners of said vehicles will be able to have the software updated at their nearest FCA dealerships. Once done, owners could expect better emissions performance that should not impact performance or fuel efficiency in any way.
