Core:

• 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.
