This DTC + AFT Reset Tool is a plug & play tool that will reset your fault codes and aftertreatment (DPF / SCR) system. This product is used solely for the purpose of clearing “Active or Inactive” fault codes in the ECUs of the vehicle.
Specific trucks will display fault codes on the dashboard, and most of the time you will have a check engine light or a check module message. After this, a screen will appear stating that the error has occurred. Many of the codes that do appear on your dashboard fall into the category of “Ghost Code.” The phrase “Ghost Code” comes from the fact that the fault code activated was triggered by certain conditions that are near impossible to recreate.
Active fault codes do cause excessive downtime as you try to find a repair shop and after you finally find and arrive at a repair shop you are waiting possibly hours only to learn that in fact, you can make it to your next destination safely and with no problems – that the fault codes are not severe. Fault codes can mislead not only the owner and driver but also the technician into thinking there is a severe problem with the truck when there is not.
This will give you the relief you need knowing that you can make it to your destination safely while decreasing downtime. All you have to do is plug the DTC + AFT Reset Tool into the diagnostic connection and clear the fault code once. If the fault code does come back a second time, you do need to take the matter seriously. This product is used solely for the purpose of clearing active and/or inactive fault codes. Nowadays semi-trucks are plagued with fault codes, let OTR’s DTC + AFT Reset Tool be your solution to a seemingly never-ending problem.
OTR’s tool will also reset the aftertreatment system after maintenance work has been completed. Moreover, you can replace engine related sensors over the road and just plug in the DTC + AFT Reset Tool to clear and reset the system. The device will then send the proper communication data over to the specific network to perform these extensive resets.

The DPF filter was introduced in 2007 and then combined with the SCR filter in 2011. The DPF or DPF / DEF SCR system has a few components of the aftertreatment system that will need to be maintained and cleaned to ensure proper engine operation and reliability. The recommended filter cleaning for heavy haul is every 250,000 miles or 4500 hours. For regional hauling, this does get extended to every 400,000 miles or 10,000 hours. That estimated mileage is based on perfect world conditions when all component perform well.
