Once again, we can credit RVers for a solution that industry hasn’t come up with. And if that happens on the road, far from a Cummins authorized shop, well, you can see the problems that could come up.īut hang on, there’s yet another DEF head alternative, and one that may sound better. If we read the statement literally, if your DEF head hasn’t gone “gunnybag,” you’ll have to wait for it to happen. For those of you who have not actually “experienced this failure,” but have held back from heading out on the road for fear the “failure” might occur, your relief isn’t so brilliant. It’s a DEF head alternative that may offer relief for many RVers who are broken down with a bum DEF head. The Cummins statement came out Thursday, August 26.

The details are being finalized and once ready, customers will receive communication about when and where they can receive the software calibration and next steps once replacement parts become available.” Pending the outcome of discussions with regulatory agencies, we expect to begin introducing this calibration across several model years in the next few weeks. We have developed a software calibration for customers who have experienced this failure that will allow customers to continue (or resume) operating their vehicle. Here’s a quote from Cummins: “As we have shared we have been working closely with OEM and industry partners, and the regulatory agencies to find a solution that addresses the widespread shortage of replacement parts related to the DEF sensor failure. It looks like all your cries of despair may have been heard. Later, we suggested the campaign for relief include EPA officials, in addition to Cummins. RVers have been pleading with Cummins to negotiate with the EPA (Environmental Protection Agency) to allow a software change that would allow affected vehicles to continue to operate if their DEF head signals trouble with the system. In most instances, there’s nothing wrong with the DEF system, it’s just the sensors. When the control module gets a signal that there’s something wrong with the DEF system, it triggers a sequence essentially leading to the shutdown of the engine. Your pressure causes industry and government to actįor weeks we’ve been urging RVers to contact Cummins Inc., the company that has direction over the software that controls the ECMs (engine control modules) that have shut down scores of motorhomes and trucks. RVers solve problem that industry couldn’t.Your pressure causes industry and government to act.
