Have questions?

Let us know if you have any additional questions

In order to determine if we can help you we need the following details: 1. Year, make and model of your truck 2. Error code image from your dashboard 3. Make sure that your engine is warm prior to our arrival in order to activate the forced regen.
When a failure occurs, this will prompt you a “Exhaust System Failure” notification on your dash and will derate your vehicle to seek service. You’d need to take the filter off the vehicle and send it to an approved DPF cleaning shop so they can assess how badly it’s clogged. If the filter is a good candidate for cleaning, then you’d perform that service and reinstall the filter on your vehicle.
A forced DPF regen is performed when a diagnostic scan tool, starts the regen process. The DPF soot load could be too high for a passive or active regen to occur, meaning you’ll need to perform a forced DPF regen.
Absolutely not. We are emergency service, and will only erase the active, and inactive error codes to reset the derate mode and return you back on your route.
