Restore Peak Performance to Your Vehicle
Is your Cadillac, GMC, or Chevrolet suffering from baffling electrical issues, a persistent check engine light, or a no-start condition? A failing Engine Control Module (ECM) is often the culprit, acting as the vehicle’s brain and disrupting everything from fuel delivery to transmission shifting. This isn’t just an inconvenience—it’s a critical failure that compromises your vehicle’s performance and reliability. We offer the definitive, hassle-free solution: a genuine GM Engine Control Module, professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ever leaves our facility.

An Expert’s Note on Programming
Think of your vehicle as a team of specialists that all need to speak the same language. The ECM is the team captain. A generic, unprogrammed module from a salvage yard is like a captain who speaks a different dialect—it causes confusion, errors, and poor performance. By programming this 2017 Cadillac CTS engine control module to your specific VIN, we ensure it communicates flawlessly with every other system, from the anti-lock brakes to the climate control. This critical step is the difference between a temporary patch and a lasting, reliable repair.
Frequently Asked Questions
What information do I need to provide?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We cannot program and ship the module without it. This ensures you receive a part that is perfectly matched to your vehicle’s factory build.
Will this part be completely “plug and play”?
In many cases, yes. However, due to GM’s anti-theft systems, a “theft relearn” procedure may be required after installation if the vehicle does not start. This procedure syncs the new ECM to your vehicle’s security system and requires a professional scan tool with GM software (like Tis2web/Techline Connect). This, along with any other relearns (crankshaft variation, etc.), is the responsibility of the installer.
Do I need to send my old computer back?
No, there is no core charge or need to return your old module. This allows you to get your vehicle back on the road faster without waiting for return shipping.
How do I find my vehicle’s VIN?
Your VIN can be found on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this the right part to fix my check engine light?
While this 2017 Cadillac CTS engine control module is the correct fix for many ECM-related fault codes, proper vehicle diagnosis is essential. We recommend having a qualified technician diagnose the issue before ordering to ensure you are purchasing the correct part for your specific problem.
Does this fit vehicles other than the 2017 CTS?
Yes, this ECM fits a wide range of GM trucks, SUVs, and cars. Please review the detailed fitment list on this page to confirm it is the correct part for your specific year, make, and model.
