Here's the text from the letter:
At Spartan RV Chassis, we continue to make improvements to our DEF system supplied by Shaw Development, with primary focus on the DEF sensor. In January 2021, we launched a DEF sensor with greater reliability which has a shield around the DEF sensor to protect it in its environment. This new sensor was launched for both installation in production units and for field service replacement. We have seen significant improvements in sensor reliability based on this design with almost zero field failures.
In April of 2021, alongside many in the auto industry, we were impacted by the global chip shortage. This global shortage impacted the supply of components utilized in the Shaw DEF system, significantly impacting our supply of sensors and complete DEF systems for both new vehicle production and service. We were placed on supply constraint and have been managing the situation as best as possible since that time to minimize the impact to our customers, which has included long hours from our customer service and supply chain teams.
We pride ourselves in exemplary customer service, and it is a core value for our business. The last few months have been a real challenge for our team and our customers alike. We apologize for any inconvenience the DEF situation has caused our customers.
We are beginning to see major improvements in our component supply base and corresponding parts/product availability. Our goal is to eliminate our DEF parts availability issues by the end of September. To that end, we will continue to work with our service centers and coach OEM partners to address all outstanding customer issues as they arise. While this DEF system and supply issues have not been specific to Spartan, we are working with our industry partners to address the situation. We have worked closely with Cummins, the RVIA and directly with the EPA to provide options for relief to RV owners experiencing DEF system failures. We are hopeful that if agreed to and adopted, these measures could lessen the impact this system failure has had on the RV industry.
We will keep you appraised of developments as they occur in the near term as we look to put this issue behind us.
Moving forward If you experience any of the following fault codes, please contact Spartan RV Chassis at (800) 543-4277 and we will help you through the next steps you need to take with your coach.
SPN 3364 FMI 9 (Cummins fault code 3868) - Aftertreatment diesel exhaust fluid quality- Abnormal update rate.
SPN 1761 FMI 9 (Cummins fault code 4677) - Aftertreatment diesel exhaust tank level - Abnormal update rate.
SPN 3031 FMI 9 (Cummins fault code 4572) - Aftertreatment diesel exhaust fluid tank temperature- Abnormal update rate.
Also, please see the Cummins Engine Lamp Identification Guide pictured below or visit their website at www.cumminsengines.com
. This is the process the engine will go through when the DEF sensor sends a fault code to the dash. Your motorhome is not equipped with a switch to perform a parked regeneration. If your engine aftertreatment needs a forced regeneration, please contact your local Cummins service provider, or contact Spartan RV Chassis @ (800) 543.4277 for assistance with locating.
