Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the ECM correctly for your specific truck or van before we ship it.
Is this part truly ‘plug and play’?
Yes, the module arrives ready to be installed. The critical engine and transmission programming is complete. However, on some GM vehicles, you may need to perform a simple ‘Security Relearn’ or ‘CASE Relearn’ procedure, which can typically be done without special tools. Instructions are widely available online for these models.
How do I know if the ECM is definitely my problem?
While this part solves all ECM-related failures, we always recommend a thorough diagnosis by a qualified mechanic. Common indicators are internal processor fault codes (like P0601), no communication with the module, or having ruled out all other potential causes like wiring or sensors.
How long does the programming process take?
The programming is performed by our technicians after you provide your VIN. This is typically completed within one business day, ensuring we can ship your ready-to-install part to you as quickly as possible.
Will this fit my vehicle?
This ECM is compatible with a range of 2007-2010 GM trucks and vans equipped with the 6.6L LMM Duramax diesel engine. Please review the detailed fitment list on this page to confirm compatibility with your specific year, make, and model.
What kind of warranty is included?
This unit is backed by our one-year replacement warranty, giving you confidence and protection for your purchase.
