Multiply the engine hours by 33 miles or 53 km.Record the total engine hours indicated on the DIC.Use the following steps to aid in determining the equivalent mileage (kilometers): Some vehicles may spend a lot of time idling.
If there is a concern about the DPF Soot Accumulation, perform a regeneration enable and return the vehicle to the customer. Only perform a service regeneration if instructed in the appropriate Service Information. It is not as effective at lowering the soot accumulated in the DPF as a Regeneration Enable followed by a drive. If either of these reaches the threshold, a regeneration will be performed.Ī Service Regeneration is designed to lower the soot accumulation in the DPF in a very controlled way. One uses the differential pressure sensor to calculate the soot in the DPF and the other uses other engine data. There are two soot level readings in GDS2. If the DPF Soot Accumulation increases to 140%, DTC P2463 (DPF Soot Accumulation) will set and a service regeneration will be required to clean the DPF.

If the DPF Soot Accumulation increases to 115% and the system has not been able to regenerate, the “Continue Driving” message will display on the Driver Information Center (DIC). The ECM will not try to perform a regeneration until the DPF Soot Accumulation increases to approximately 100%. However, there may be circumstances that require a service regeneration to be performed.īeginning with 2017 Silverado and Sierra models, the DPF Soot Accumulation is measured in percent instead of grams in GDS 2. Under normal driving conditions, the DPF cleaning occurs without any driving involvement. 1) requires an occasional Diesel Particulate Filter (DPF) cleaning. A minimum of two and a half gallons of approved Diesel Exhaust Fluid is added to the tank to eliminate the 5mph derate.The diesel exhaust system on 2017-2018 Silverado and Sierra models and 2019-2020 Silverado 2500/3500 and Sierra 2500/3500 models equipped with the 6.6L Duramax diesel engine (RPO L5P) (Fig. The system will arrive at this level with approximately 0.7 gallon of fluid left in the tank. The customer will hear a chime and get an EVIC message reading "5 mph Max Speed Refill DEF". The customer will hear a chime and get an EVIC message reading "Speed Limited to 5 mph in XXX MILES Refill DEF". The second warning level will occur when the tank level is at approximately 1.5 gallons. The customer will hear a chime and get an EVIC message reading "DEF Low REFILL Soon". The driver warning and inducement strategy for a low fluid condition is as follows: The first warning will occur when the tank level is at approximately two gallons.

There are a series of three warning levels to indicate to the customer when the fluid is low or incorrect.
RAM DTC P203F Make: RAM Code: P203F Definition: (Diesel Exhaust Fluid) Reductant Level Too Low Description: The Diesel Exhaust Fluid (DEF) system holds a total of 5.7 gallons of fluid on a regular cab and 9.2 gallons of fluid on a chassis cab vehicle.
