Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before the unit ships. It will arrive flashed to your specific VIN with the latest GM updates. You may need to perform a simple security relearn procedure (often called a key relearn or anti-theft relearn), which typically takes 10-30 minutes and requires no special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot program and ship the module without it. Please double-check it for accuracy to ensure a perfect match.
Is this a simple plug-and-play installation?
Yes, for the most part. The physical installation involves disconnecting the battery, removing the old module, and plugging this one in. After that, the security relearn procedure syncs the new ECM with your vehicle’s anti-theft system. For some vehicles, a Crankshaft Variation (CASE) relearn may be required, which can be done with many professional-grade scan tools.
What if my original part number isn’t 19210738?
This module is a direct replacement for several part numbers. As long as your original part number is 12589297, 12597121, 12603892, or 19210738, this unit will be a compatible, programmed replacement for your vehicle.
Will this fix my specific problem?
While this programmed 2007 Sierra 3500 ECM is the definitive solution for a failed module, it’s crucial to ensure your vehicle has been properly diagnosed. This part corrects issues stemming from a faulty computer but will not fix underlying mechanical or wiring problems.
How long does the programming and shipping process take?
Programming is typically completed within one business day of receiving your VIN. Shipping time will then depend on the method you select at checkout. Our goal is to get you the correct part as quickly as possible to minimize your vehicle’s downtime.
