Restore Your Vehicle’s Performance and Reliability
Is your Buick, Cadillac, or Chevrolet suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or poor fuel economy? These are classic signs of a failing Engine Control Module (ECM), the central computer of your vehicle. When the ECM falters, it can disrupt your daily drive and leave you stranded. This pre-programmed Engine Control Module is the definitive solution to restore your vehicle’s original performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, often leading to incorrect diagnoses and costly, unnecessary repairs. If you’re experiencing any of the following, this module is your answer:
- Check Engine Light (CEL): Often with communication error codes (U-codes) or multiple, seemingly unrelated sensor codes.
- Engine Stalling or Misfiring: Unpredictable stalling at stops or hesitation during acceleration.
- No-Start Condition: The engine cranks but refuses to start due to a lack of fuel or spark command from the ECM.
- Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- Failed Emissions Test: Inability to pass smog tests due to ECM-related faults.

We’re not just selling you a part; we’re delivering a fully integrated component that’s ready to restore the precise, factory-spec operation of your vehicle. This is the difference between a temporary patch and a lasting repair.
Don’t let a faulty computer dictate your vehicle’s reliability. By choosing our programmed 12637106 engine control module, you are investing in a dependable, long-term solution that brings back the smooth and efficient performance you expect from your car. Simply provide your VIN during checkout, and we’ll handle the complex programming for you.
Frequently Asked Questions
Do I need to do any additional programming myself?
No. This ECM arrives fully programmed to the VIN you provide. In most cases, it is a direct plug-and-play installation. Some vehicles may require a simple security or crankshaft position sensor relearn, which can often be done without special tools. Instructions can be provided if necessary.
Where can I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Is this a direct replacement for my original part number?
Yes. This module is a direct replacement for multiple GM part numbers, including 12637106, 12616889, 12630908, 12642665, 12650256, and 12651993. Please check the fitment list to confirm it matches your vehicle.
What happens after I place my order?
After you purchase, you will need to send us your VIN. We cannot ship the part until we receive this information. Once we have your VIN, we will program the module and typically ship it within one business day.
How can I be sure the ECM is the problem?
While the symptoms listed are strong indicators of a failing ECM, it’s always best to have a professional diagnosis performed. Common diagnostic trouble codes (DTCs) related to internal processor failure, communication errors (U-codes), or multiple unrelated sensor faults often point directly to the ECM.
