If there seems to be something wrong with our newly sent ECM upon arrival, be sure to call us first to see if there might be a quick fix. There are a few common hiccups that can occur during initial installation that are easily remedied with a little phone support. And sometimes what seems like an ECM failure later in the Warranty Period can be something else. We can save you time and energy getting to the root of the problem quickly. 

When we’ve agreed the best course of action is to for us to send you a replacement, please complete the following form and click on Submit. The more detailed information you provide about the problems, the better. After completing the form, you will receive an email with a Return ECM Authorization (ERTA) Number. Ideally, just print that email and pack it in the box with your ECM per our Packing & Shipping Guidelines. If you don’t have access to a printer, please complete the form below anyway as it helps us be on the lookout for the Return and to ship a replacement faster. In such cases, include a note in the box with your name, email address, Tel#, and the REA Number.

packing & shipping guidelines

If you still have the original box, pack your ECM securely in it along with a detailed note or printout of the Return Form Confirmation email you will receive after submitting the Return Form. If you no longer have the original box, take your ECM to the nearest post office and ask for the Priority Mail Medium Flat Rate Box. (Some extra large Cummins Diesel Engine ECMs may call for the Large Flat Rate Box). Don’t forget to bring packing tape. Padding materials (foam peanuts / bubble wrap can be purchased at the Post Office, or bring your own. Use our prepaid return label.

IMPORTANT!  Plastic plug receptacles are easily broken during shipment if not properly packed. 

Pack as shown:

  1. Put 1/3 of padding materials (foam peanuts or bubble-wrap) beneath ECM.
  2. Pack ECM centered with flat side down. Plugs should be facing up.
  3. Put 2/3 of padding materials around and above the ECM.
  4. Fill completely to the top before sealing box.
