The Duramax LM2 CAN BUS Plug for 2020-2022 Silverado 1500 and Sierra 1500 LM2 diesel trucks is an essential upgrade for anyone performing delete tuning. It ensures proper communication between the ECM and modified components, preventing common issues like error codes or limp mode after removing emissions systems.


Why You Need It

This kit is designed for trucks equipped with aftermarket exhaust systems or delete pipes. When removing the DPF/DEF systems it replace the NOx and DEF modules. It sends a closed signal back to the ECM to ensure proper vehicle operation. Unlike some others that only supply two NOX plugs, we supply 3 NOX plugs and a DEF tank plug.  Your specific truck may use a different NOX module in the engine bay and the provided plugs will not fit.  In this case you will leave the factory module plugged in and only remove the two NOX modules located underneath the truck, leaving you with an extra NOX plug.  If your truck's engine bay NOX module uses the same plugs as the ones underneath, you can use the CAN plug in the engine bay as well.


Key Features:

  • Compatibility: Perfectly engineered for 2020-2022 Silverado 1500 and Sierra 1500 LM2 diesel trucks.

  • Delete Tuning Requirement: Vital for vehicles undergoing delete tuning, ensuring smooth ECM operation after emissions system removal.

  • Aftermarket Ready: Seamlessly integrates with aftermarket exhaust systems or delete pipes.

  • ECM Signal Management: These plugs replace NOx and DEF modules, sending a closed signal back to the ECM for optimal function.


The Duramax LM2 CAN BUS Plug provides a hassle-free solution for maintaining vehicle performance when modifying exhaust systems. It's crucial for ensuring that your truck runs smoothly, even without the factory emissions components.

For the best results, install the kit professionally, especially if you are new to tuning or emissions modifications. This prevents check engine lights and communication errors between the ECM and your truck's modified systems.


Note: This product is for off-road use only. Make sure to verify local regulations before installing.

Save money by installing yourself
Size: 9.5" x 10.9" x 2.1"
Good price and easy to install in a 2019 Honda CRV. Instructions can be found on YouTube. Much less expensive than having a service center install them.

Always fits and is easy to install
Size: 9.5" x 10.9" x 2.1"
We've bought these for years and they always fit and are easy to install. Easy to see when they are dirty and need to throw away. Embarrassed that we let the car dealership do it for so long. We set on six-month subscribe and save so that we know when to replace it - change it whenever it shows up!
