Fiat Chrysler’s U.S. division said Friday it is voluntarily recalling over 1 million trucks in the U.S. to reprogram computer modules that help control restraint-system deployment in rollover situations. The error has reportedly been linked to two injuries and one death from a crash.

The error code associated with the warning may temporarily disable side air bag and seat belt pretensioner deployment, which would then be unavailable in the event of a vehicle rollover. Pretensioners reduce seat belt slack during impacts.

The company said it has identified a number of vehicles equipped with modules featuring certain types of sensors.  If such a vehicle were subjected to a significant underbody impact, its module may erroneously conclude the sensor has failed and then activate an instrument-cluster warning light.

Affected vehicles are certain 2013-16 Ram 1500 and 2500 pickups, and 2014-2016 Ram 3500 pickups. Their occupant restraint control modules will be reprogramed with software that affords more robust sensor performance, said the carmaker.

The recall also affects an estimated 216,007 vehicles in Canada; 21,668 in Mexico; and 21,530 outside the NAFTA region.
