Johnny’s RV Works, maker of the Rescue-Ranger and EZ Switch, has introduced its complete plug-and-play line of analog and digital DEF head sensor simulators and controller.
Rescue-Ranger is a patent-pending comprehensive analog and digital product line designed to work with 2010-2016 Freightliner, Spartan and PowerGlide diesel-powered motorhome chassis as well as 2017-Current motorhome diesel chassis. The EZ Switch controller allows flexible on/off use of the simulators, the company said.
The plug-and-play product line can be used as either a curative or preventive measure to address the effects of commonplace DEF head sensor failure. Once a DEF head sensor error code is experienced, coach functionality will become limited as the result of the built-in “derating” process. Once fully derated a coach will enter “limp” mode whereby maximum travel speed is 5 mph and recovery can only be accomplished at a Cummins service facility, Johnny’s RV Works said.
“This is a cutting edge product in the marketplace,” said John Getter, president of Johnny’s RV Works. “We have designed the Rescue-Ranger and EZ Switch to not interfere with any motorhome chassis emissions system. With the Rescue-Ranger simulator products in use, the motorhome remains 100% emissions compliant.”
The RV industry at large and diesel powered motorhome users are acutely aware of the frequency of DEF head sensor failure and its undesirable consequences, the company said. Additionally, the availability of replacement DEF head sensor parts remains costly and unpredictable.
Johnny’s RV Works owner, John T. Getter, is an authorized Cummins repair technician and recognized the need for a simulator that would allow coach owners to have full use of their motorhome even if a DEF head sensor error code was already present. “It was important that the coach retain its full functioning emissions systems and stay fully compliant and remain 100% drivable,” Getter said.
