About 5-6 weeks ago I was towing home from Disney, Ok and my truck said Service DEF system, see dealer, and started counting down from 200 miles until limp mode. It is my DD and I tow a 5th wheel toyhauler that weighs just under 15k loaded. What does service DEF system, see dealer mean?

What does it mean when your check engine light comes on?.

Where did the Def service warning come from?.What kind of car has a Def service message?.Can a service DEF system engine not start in 200 miles?.How many miles does dash say in 140 miles?.How to reset service DEF system its Sunday no deal?.What kind of service DEF system does Dodge Ram use?.Can a service DEF system go into limp mode?.Why was my service DEF system turned off twice?.What does service DEF system, see dealer mean?.Turn the ignition on and ensure that the DEF level gauge is reading correctly.Ħ8192659AC.Module kit, urea pump/level unitĦ8035704AB.Diesel exhaust fluid (1 gallon)Ħ8056278AB.Diesel exhaust fluid (2. Using wiTECH, perform a DEF Reductant Doser Pump Prime Override test a total of 10 times to ensure that the DEF pump has been sufficiently primed and that all air has been purged from the pump and filter. Ensure that the DEF tank is approximately one-half full. DTCs may be present, including P203B (reductant level sensor circuit performance), P203C (diesel exhaust fluid reductant level sensor circuit low) or P203D (diesel exhaust fluid reductant level sensor circuit high). The sensor translates this signal change into a fluid level and buses the information to the IPC (instrument panel cluster) via the DCU (dosing control unit).Ī manufacturing defect in the level sensor may have occurred if built on or after April 1, 2014, and on or before Sept. As the fluid level in the tank decreases, the level sensor becomes exposed to air which alters the signal sent out by the sensor. The DEF system uses a complex radio frequency type level sensor to detect the amount of fluid present in the DEF tank. A defect may be present with the DEF (diesel exhaust fluid) level sensor. This bulletin applies to 2014-2 trucks equipped with a 6.7L Cummins diesel engine.
