FCA 3.0-litre EcoDiesel engine

Fiat Chrysler Automobiles (FCA) has updated its diesel emissions software to clear up an emissions investigation from earlier in 2017, and has applied for certification from the EPA and CARB for select new Jeep and Ram models.

The company updated its software due to emissions cheating allegations that came to light in January 2017, affecting about 104,000 diesel Jeep Grand Cherokees and Ram 1500s from 2014-16 model years. Shortly after the US government indicted Volkswagen officials for emissions cheating, the Environmental Protection Agency and the California Air Resources Board issued allegations that FCA installed and didn’t disclose software that could have been used to fool emissions tests on the company’s 3.0-litre diesel engines, though nothing was ever proven.

FCA worked with the EPA and CARB to clarify the issues surrounding the FCA emissions control technology, including extensive testing of new diesel vehicles, to come up with the updated software that will allow the company to market the two models for the 2017, using the 3.0 turbodiesel.

FCA intends to install the same software in the previous model years’ vehicles, believing it will address the environmental agencies’ concerns about the company’s emissions software calibrations, and also facilitate a resolution to ongoing discussions with US government departments of the environment and natural resources. FCA is also claiming the new software will improve emissions performance without impacting performance or fuel efficiency.

Following confirmation from all government sources, FCA is hoping to start calling owners of 2014-16 Jeep Grand Cherokees and Ram 1500s to dealerships to update the software.
