Diesel control module repair — bench-tested, mail-in nationwide.

Straightforward process

How it works with ECM Lab Works

You need clarity: what to ship, where to send it, and what happens while your module is on the bench. Here is the flow from order to tested unit heading home.

From order to return shipment

Your dashboard stays the source of truth for status and messages.

  1. 1

    Open your order

    Create an account and submit a repair with module type, symptoms, and VIN when it matters. The more detail up front, the faster we can route the job.

  2. 2

    Ship the module

    Pack securely and send it in. Add inbound tracking from your dashboard when you have it so we can anticipate arrival.

  3. 3

    Bench diagnosis and repair

    We diagnose at the component level, repair what failed, and verify on appropriate equipment—not swap-and-hope.

  4. 4

    Programming where required

    When your application needs calibration or security alignment, we program to your VIN and specifications as discussed for the job.

  5. 5

    Stay informed

    Customer-visible notes and status live on your order page. Check anytime instead of chasing updates by phone.

  6. 6

    Ship back, traceable

    When testing is complete, we prepare outbound shipment with tracking so you know when the module is on the way home.

Why shops and owners use a dedicated lab

Predictable process, accountable work, and communication that respects your time.

  • Heavy-duty focus

    ECM and CPC platforms for commercial diesel—experience where it counts.

  • Honest expectations

    Turnaround follows the service you select and what we see on inspection—no vague promises.

  • Documented testing

    Verification on the bench before return reduces comebacks after install.

  • One place for updates

    Dashboard notes and status reduce email threads and phone tag.
