  Summary

  Flash: Instrument Panel Cluster (IPC) Updates Customers may experience one or more of the following: ● While driving, resetting the Diesel Particulate Filter (DPF) gauge causes the IPC to freeze on that screen. The left-side steering wheel controls (used for navigating the IPC) becomes unresponsive while the right-side controls for cruise control remained functional. ● Power Take-Off (PTO) Password feature not able to reset. ● The IPC may incorrectly display an airbag warning light. ● Opening the driver door while the IPC is in sleep mode may cause the analog gauges to momentarily flutter. ● The navigation option does not appear in the main IPC menu. However, it can still be accessed through the Favorites screen. (When cycling through the main menu, option #5 is listed as Audio, but in the Favorites menu, option #5 correctly shows as Navigation). This bulletin involves updating the IPC with the latest available software.

  Summary

  On Cummins diesel applications that are for 2019 and newer the bpro part 1BP00507AB can on occasions create a check engine light. In these situations, it is recommended to use the appropriate Mopar air filter (57008652AA). The "AC" level of the part is in development to resolve this issue. 1BP00507AB should still be usable for 2018 and older Model year Cummins engines.
