Restore Your Vehicle’s Brain, Not Just a Part
Is your Cadillac, Chevy, or GMC truck suffering from baffling electrical gremlins, a persistent Check Engine Light, or a frustrating no-start condition? You’re not just dealing with a faulty component; you’re dealing with a failure of the vehicle’s central command center. This Programmed 12676230 Engine Control Module is the definitive, dealership-alternative solution to restore your vehicle’s performance, reliability, and drivability. We take the complexity out of the repair by pre-programming this unit specifically to your vehicle’s VIN, ensuring it’s ready to install right out of the box.
Common Symptoms of a Failing ECM & Your Solution
A failing Engine Control Module can manifest in numerous ways that can be misdiagnosed, costing you time and money on unnecessary parts. If you’re experiencing any of the following, this module is your likely solution:
- Persistent Check Engine Light: Often with communication error codes like P0601, P0602, P0606, or U-series codes.
- Engine Performance Issues: Unexplained stalling, rough idling, hesitation during acceleration, or a noticeable drop in fuel economy.
- Starting Problems: The engine cranks but refuses to start, or starts intermittently.
- Erratic Transmission Behavior: Harsh or delayed shifting that isn’t related to the transmission itself.
- Apparent Failure of Other Components: The ECM can send false signals, making it seem like sensors or other modules have failed.
This professionally prepared Programmed 12676230 Engine Control Module directly addresses these issues by replacing the faulty hardware and software with a fully updated, vehicle-specific unit.
An Expert’s Note: In today’s vehicles, the ECM is the heart of a complex communication network. It’s not just a simple swap like an alternator. Every module is tied to the vehicle’s security system (like GM’s VATS or Passlock). Simply installing a used, un-programmed module from another vehicle will result in a no-start condition every time. Our VIN-programming service handles this critical security handshake for you, saving you a tow and a costly programming session at the dealership.

Frequently Asked Questions
What is the process after I place my order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot ship the module until we have this information. Our technicians use your VIN to load the correct, updated software from GM, making the unit specific to your car or truck.
Will I need to do any additional programming myself?
No. The unit arrives ready for installation. In most cases, once installed, you can simply start the vehicle. Some vehicles may require a simple crankshaft position sensor relearn procedure, which can be done with a capable scan tool or by following a specific drive cycle.
How do I find my vehicle’s VIN?
Your VIN can be found in several places: on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
How can I be sure this fits my vehicle?
Please check the extensive fitment list on this page. The most accurate way is to match the part number from your existing module to one of the compatible numbers listed (e.g., 12676230, 12692067, etc.). If you are unsure, please contact us with your VIN before ordering.
What does the one-year warranty cover?
This unit is backed by our one-year replacement warranty. This covers any functional failure of the module itself during the warranty period. It does not cover damage from improper installation or external vehicle faults.
