Restore Your Vehicle’s Performance and Reliability
Is your Cadillac, Buick, or GMC suffering from frustrating and unpredictable issues? A flashing check engine light, sudden stalling, poor fuel economy, or a complete no-start condition often points directly to a failing Engine Control Module (ECM). Don’t let a faulty computer keep you off the road. This is your direct, reliable solution—a professionally programmed ECM that restores your vehicle’s brain to perfect working order, getting you back behind the wheel with confidence.
Common Symptoms of a Failing ECM & Your Direct Solution
A failing engine computer can cause a wide range of problems that can be difficult to diagnose. If you’re experiencing any of the following, a faulty ECM is the likely culprit:
- Check Engine Light is on with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606.
- Engine cranks but refuses to start.
- Vehicle stalls intermittently while driving or at idle.
- Noticeable decrease in fuel efficiency.
- Erratic automatic transmission shifting.
- Loss of power and poor acceleration.

Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles like your CTS or Acadia, the ECM is the central hub of a complex communication network. It talks to the transmission, ABS, body control module, and even the instrument cluster. Simply installing a used, non-programmed module from a junkyard will cause communication failures, anti-theft system lockouts, and a host of other problems. Our VIN-specific programming service ensures that your new Programmed 12635019 ECM is recognized by your vehicle as the original, allowing all systems to communicate and function exactly as the manufacturer intended. It’s the critical step that ensures a successful and lasting repair.
Frequently Asked Questions
How does the programming process work?
It’s simple! After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to download the correct, most up-to-date software from GM and flash it onto the ECM before we ship it to you.
Why do I need to send in my old ECM for a Camaro or LaCrosse?
For the Chevrolet Camaro and Buick LaCrosse, the vehicle’s unique immobilizer (anti-theft) data is stored in the original ECM. To make your new unit truly plug-and-play, we need to extract this data from your old module and transfer it to the new one. We will provide instructions for this simple process after your purchase.
Will I need to do anything else after installing this ECM?
For most vehicles, no. Once installed, the pre-programmed ECM should function immediately. In some cases, a Case Relearn or Crankshaft Position Sensor Relearn procedure may be needed, which can be performed with a capable scan tool. This is a standard procedure after replacing an ECM.
Where is the VIN located on my vehicle?
You can typically find your VIN on a sticker inside the driver’s side door jamb, on a plate on the driver’s side of the dashboard (visible through the windshield), or on your vehicle’s registration and insurance documents.
Is this a genuine GM part?
This is a high-quality replacement module that is fully compatible with the listed GM part numbers. It is loaded with official GM software to ensure factory-level performance and reliability for your vehicle. Our Programmed 12635019 ECM is built to meet or exceed original specifications.
