This is Genuine GM Duramax Diesel replacement electronic control module (ECM).

Additional Services:

  • Vin Assignment: DHD can bench flash your vin into the ECM for $150.00. This covers both the Service and MDI license required to do so.
  • Security Disable: DHD can disable the VATS security and make this ECM plug and play for $125.00. The security relearn procedure can be cumbersome and time consuming, especially without a Tech 2 scan tool. Disabling the VATS will make the install process much easier.


  • DHD does require cores on all ECM's New and Used. Your core must be physically intact, with no connector, terminal or case damage. The core you return must match the model and type you received. Cores do not need to function electronically and can smell burnt.
  • To avoid paying the core charge up front, you can select the "Return Core First" option in the menu above. When this option is utilized we will hold your order until the core is received.
