  Flash: Instrument Panel Cluster (IPC) Updates Customers may experience one or more of the following: ● **The IPC does not display the correct Tire Pressure Monitoring System (TPMS) graphic in the IPC (For dually vehicles only) Fig. 1.** ● 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.
