Product Description
Dyno Diesels CAN Communication Plug Kit
Chevy / GMC Duramax L5P | 2017–2025
Required After DPF / DEF Delete
Stable Network. Clean Signals. Reliable Operation.
The Dyno Diesels CAN Communication Plug Kit is designed to maintain proper CAN bus integrity on 2017–2025 Chevy and GMC L5P Duramax trucks after emissions components such as the DPF and DEF system are removed for off-road or competition use.
Modern L5P platforms rely heavily on Controller Area Network (CAN) communication between engine, emissions, and vehicle control modules. When emissions modules are removed, the CAN network can be left open or improperly terminated, which may cause communication faults, warning messages, or drivability issues. This kit provides a clean, engineered solution to stabilize the network.
Why a CAN Plug Kit Is Required on L5P Duramax
After DPF/DEF deletion, the factory emissions control modules are no longer present on the CAN network. Without proper termination, this can lead to:
- CAN communication errors
- Warning messages or fault codes
- Limp-mode conditions
- Intermittent drivability or tuning issues
The Dyno Diesels CAN Plug Kit ensures the network remains properly terminated and balanced, allowing remaining vehicle modules to communicate normally.
Key Benefits
- Maintains proper CAN bus termination after emissions module removal
- Helps prevent communication-related fault codes
- Supports stable tuning, diagnostics, and data logging
- Plug-and-play design—no cutting or splicing required
- Clean, professional alternative to improvised wiring solutions

- (2) CAN communication termination plugs
- (2) 6-foot CAN extension cables
