What does ‘SCR NOx conversion efficiency low’ mean on Detroit Diesel DD13, DD15, DD16? Fault codes associated with Selective Catalyst Reduction (SCR) NOx efficiency low are the most dreaded codes you will find on the Detroit diesel application and can drive your costs high. Long story short, these fault codes mean that the efficiency in the aftertreatment system, aka the 1-Box, is not operating within the required threshold (70%). This measurement happens between your inlet and outlet NOx sensors and it’s called your SCR NOx efficiency. If the SCR NOx efficiency goes below 70%, then these fault codes get set “Active.” The only way you can clear these codes is by doing a forced regen with the SCR NOx efficiency above...

Owner-operator - IG TransCraft Express LLC Ilya has been driving across the United States with his dog, “Diesel.” When Illya first used the reset tool he said he had to wait until a check engine light appeared to see if it’s an actual problem with the truck or if it’s a Ghost code. Ilya was left shocked when he plugged it in and it actually cleared the codes. Ilya wanted a tool to keep him on the road without any added downtime due to fault codes coming from the Engine & Aftertreatment system. Ilya is now in control of his system and will continue to use the reset tool when something comes up. Ilya is a proactive owner-operator who takes the...

If you have a paccar powered truck that is 2011+, then you need to be aware of your emission system. Learning about this system will ensure you are prepared before a breakdown occurs. The paccar emissions are complicated. The reason we say this is because there are two aftertreatment ECUs for paccars. One is used to control the DEF system and the other one is used to control the DPF system and keep the aftertreatment in sync with the engine ECU. There are many different components that make up the DPF & DEF system. So it is best to understand the limitations so you are not stranded over the road.  5 MPH DEF derate explainer: If you have an emissions related...

Parked regen light flashing?  This light is only available when the truck is requesting a parked regen. Every truck manufacturer designs this feature to appear when the soot level in the DPF filter reaches a certain level in order for the truck to keep operating. What does this “soot” look like? When your truck is requesting a parked regen it means that the passive regen your truck already went through was not enough to burn the soot in your DPF filter.  Do you actually need to do a parked regen when the truck is asking for it?  The short answer is, Yes! If you keep driving your truck without doing a parked regen your truck will enter a derated mode....

Electric trucks may not be a thing in the distant future any longer. Volvo announced a statement saying that they will release 15 electric class 8 semi-trucks in Southern California and that by 2020 fully electric trucks will be available for purchase by the public.  Not only this but Volvo plans on releasing a fully autonomous, fully electric class- 8 semi-truck with no cab and no emissions, which they named Vera. Volvo does believe this will help the transportation industry in various ways. Volvo also believes it will help ease the shortage of drivers and foster faster, more efficient deliveries based on the fact that an autonomous, fully electric truck can be operated at all times of the day or night with no...
