Gauge is displaying a level not representative of what is in the tank. In some cases the level drops below the low level warning and customers gets an EVIC warning. When DEF level is too low the vehicle will be derated to 5 mph after 200 miles of dropping below the low level warning. From MY13 to MY24, the DEF pump had the level sensor integrated into the pump, but this changed for MY25+. In MY25 and beyond the sensor is now welded to the DEF tank. Technicians are replacing DEF pumps for faulty level sensor concerns. Replacing the DEF pump will do nothing to improve issues with the DEF level gauge. DEF pumps being replaced for level sensor/gauge issues has now become one of the most significant warranty issues for the DEF system as a whole. DEF system Eng. team is currently working with Cummins (who owns the PCM) to properly filter the signal sent from the DEF level sensor in the tank, to prevent the erratic gauge readings.

SYMPTOM/CONDITION: Fore-aft function does NOT work when actuating the seat switch. DIAGNOSIS: 1) Put seat in position for inspection. 2) Disconnect seat wire harness motor connector from the fore-aft motor on the seat adjuster, wait 10 seconds, and reconnect. 3) Verify function of the fore/aft adjuster. Step 1. Open 2nd row door and function rear seat cushions up to stowed position. Step 2. Adjust the driver front seat to the full up position. Use switches on the side shield to move power seat fully up. Step 3. Remove the 4 bolts that hold the seat to the truck floor and discard. The bolts have lock patch that is not reusable. Step 4.

prior to replacing seatbelt please inspect for debris and any build up on the webbing and DRing. If evidence of debris and build up, please clean seatbelt webbing or turning loop as described below. Seat Belt Maintenance: Do not bleach, dye or clean the belts with chemical solvents or abrasive cleaners. This will weaken the fabric. If the belts need cleaning, use a mild soap solution or lukewarm water. Do not remove the belts from the vehicle to wash them. Dry with a soft cloth. Sun damage can also weaken the fabric. Replace the belts if they appear frayed or worn or if the buckles do not work properly. NOTE: If the belts retract slowly, inspect the upper turning loop for soiling. If soiling is present, clean with a wet soft cloth until all residue is removed.
