So what would happen, wondered MarkвЂ™s team, if they could construct a device that took the place of the DEF head, and simply told the engine control module вЂњwhat it wanted to hearвЂќ? You might think this would allow folks to cheat and not use DEF at all. If not, the ECM (engine control module) is programmed to start the dreaded de-rating process, which leads to an eventual maximum speed of 5 miles per hour. As long as the engine control module вЂњhearsвЂќ from the DEF head that all these parameters are in range, all is good. This part also reports the temperature of the DEF is in a safe range. It relates that there is, in fact, DEF in the tank (quantity). The DEF head communicates the quality (or concentration of urea) of the fluid is within spec. Essentially, the DEF head monitors the DEF system. With two DEF heads in hand, one that was working, the other that had failed, they were able to determine just what a working DEF head does. Soon Mark and others of interest formed a development group, bent on coming up with a DEF head alternative. A bit of Internet research soon revealed the scope of the problem of bad DEF heads вЂ“ and it yielded some other RVers interested in solving the problem вЂ“ even if industry couldnвЂ™t. Happily, a dealer was able to replace his DEF head in short order, but the whole experience left Mark with a bit of anxiety вЂ“ what if it happened again? He had an 8,000-mile journey planned, and having the DEF head give up the ghost again could leave him in a bad spot. In Florida, Mark, like loads of other RVers, got that dreaded DEF check engine light. Mark and his motorhome found themselves on a two-month trip. RVers solve problem that industry couldnвЂ™t Mark is deeply immersed in all things tech, and shortly after he got his coach, started making a host of modifications to the thing, and now can вЂњvoice commandвЂќ a whole lot of things the rest of us mortals would have to get up and push a button to do. is a smart guy who got into the RV lifestyle when he bought his first rig, a Newmar diesel motorhome. Once again, we can credit RVers for a solution that industry hasnвЂ™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.Д«ut hang on, thereвЂ™s yet another DEF head alternative, and one that may sound better. If we read the statement literally, if your DEF head hasnвЂ™t gone вЂњgunnybag,вЂќ youвЂ™ll have to wait for it to happen. For those of you who have not actually вЂњexperienced this failure,вЂќ but have held back from heading out on the road for fear the вЂњfailureвЂќ might occur, your relief isnвЂ™t so brilliant. ItвЂ™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.вЂќ 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. HereвЂ™s a quote from Cummins: вЂњAs 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, thereвЂ™s nothing wrong with the DEF system, itвЂ™s just the sensors. When the control module gets a signal that thereвЂ™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 actДЇor weeks weвЂ™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.
