GM Duramax LM2 CAN BUS Plug Kit (2020-2022)

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 replaces 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.

Installation Notes

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 helps prevent check engine lights and communication errors between the ECM and your truck's modified systems.
