This isn’t just a part; it’s a comprehensive solution for your 2006-2007 Silverado 2500 ECM needs.
Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM is delivered to you fully programmed for your vehicle. All you need to do is provide us with your VIN during checkout. It is designed to be a plug-and-play installation, though a simple security relearn procedure may be necessary.
What is the security relearn procedure?
For most GM vehicles of this era, it’s a simple process you can do yourself. After installing the ECM, turn the key to the ‘ON’ position for 10-12 minutes, then ‘OFF’ for 30 seconds. Repeat this cycle three times. On the fourth try, the vehicle should start, having learned the new module.
Will this fit my 2007 GMC Sierra 3500 Classic?
Yes. This ECM fits a range of 2006-2007 GM trucks and vans with the 6.6L LLY diesel engine, including the Silverado 2500/3500, Sierra 2500/3500 (Classic body style for 2007), and Express/Savana vans. Please check the fitment list to confirm your specific model.
Where do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, we will send you an email requesting your VIN. Simply reply to that email, and our technicians will handle the programming before shipping your part.
Which exact part number will I receive?
The part numbers listed (e.g., 12604137, 12606126) are all interchangeable. You will receive a fully compatible hardware unit that is programmed with the correct software for your VIN, ensuring perfect function regardless of the number on the sticker.
