Restore Your GM’s Brain and Get Back on the Road
Is your Escalade, Sierra, or Corvette suffering from frustrating and hard-to-diagnose issues? A failing Engine Control Module (ECM) can cause a cascade of problems, from a simple check engine light to a vehicle that refuses to start. This isn’t just an inconvenience; it’s a disruption to your work, your family, and your peace of mind. Stop the guesswork and replace the core of your vehicle’s engine management system with this professionally VIN-programmed ECM, designed to restore factory performance and reliability.
Common Symptoms of a Failing ECM & Your Solution
If you’re experiencing any of the following, a faulty ECM is a likely culprit:
- Persistent Check Engine Light (CEL) that won’t clear
- Vehicle is in “limp mode” with reduced power
- Engine cranks but will not start
- Erratic idling, stalling, or hesitation
- Poor fuel economy and performance
- Communication errors with diagnostic scan tools (U-codes)
- Apparent transmission shifting problems
This programmed 12692068 engine control module is the definitive solution. We take the hassle out of the replacement process by flashing the unit with the latest official GM software updates, tailored specifically to your vehicle’s VIN.

An Expert’s Note on Programming
In today’s complex vehicles, the ECM is more than just a computer; it’s the central hub that talks to the transmission, the anti-theft system, the instrument cluster, and more. Simply installing a used module from another vehicle won’t workโit’s like trying to use the wrong key for a lock. Our VIN-programming service is critical because it writes your vehicle’s specific identity into the module. This process ensures the anti-theft system recognizes the new ECM, the transmission shifts at the correct points, and the engine operates with the precise fuel and timing maps designed for it. This is the difference between a quick fix and the right fix.
By purchasing this programmed 12692068 engine control module, you are not just buying a part; you are investing in a reliable, professional solution to get your vehicle running right. After your purchase, simply provide us with your VIN, and we’ll handle the critical programming step before it even leaves our facility.
Frequently Asked Questions
Is this ECM ‘plug and play’?
While we handle the main programming to your VIN, many modern GM vehicles require a security or ‘theft deterrent’ relearn procedure upon installation. This is a security handshake between the new ECM and your vehicle. This procedure, along with any other necessary setups like crankshaft variation or injector flow rate programming, is the responsibility of the installer and may require a professional scan tool with GM software (like Tis2web/Techline Connect).
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, please send us a message with your 17-digit VIN. We cannot program and ship your module without it. Please double-check the VIN for accuracy to ensure a perfect match.
Do I need to send my old computer (core) back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
My original part number is slightly different. Will this still work?
This module replaces several part numbers, including 12704476, 12686382, 12674052, 12674472, and 12678815. If your part number is on this list and your vehicle model is in the compatibility chart, it is the correct replacement. If you are unsure, contact us with your VIN before ordering.
What tools are needed for the theft relearn?
The theft relearn procedure typically requires access to GM’s official programming software, such as Tis2web or the newer Techline Connect, used with a compatible J2534 interface tool. We recommend having this done by a qualified automotive technician or a shop with the appropriate equipment.
Will this fix my check engine light?
If the check engine light and associated running issues are caused by a faulty ECM, this programmed 12692068 engine control module is the correct solution. However, we always recommend a thorough diagnosis by a qualified technician to confirm the ECM is the point of failure before purchasing.
