Restore Your Cadillac’s Peak Performance
Is your 2010-2011 Cadillac STS, CTS, or other compatible GM vehicle suffering from frustrating and hard-to-diagnose issues?

This is the definitive fix to get you back on the road with confidence and peace of mind.
Common Failure Symptoms & Your Direct Solution
A faulty ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a failing engine computer is a likely culprit:
- Persistent Check Engine Light (CEL)
- Vehicle won’t start or has difficulty starting
- Engine stalling, sputtering, or running rough
- Noticeable decrease in fuel economy
- Transmission shifting issues or harshness
- Communication error codes (U-codes) with diagnostic scan tools

Frequently Asked Questions
Do I need to do anything after installing this ECM?
In most cases, you will need to perform a security relearn procedure (also known as a key relearn or anti-theft relearn). This process syncs the new ECM with your vehicle’s existing keys and security system. It typically takes 30-40 minutes and can be done without any special tools. We can provide instructions for this simple procedure.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot program and ship the module without it.
What if I have a Camaro or a LaCrosse?
For these specific models, the immobilizer information is stored differently. To ensure a true plug-and-play installation, we require you to send us your original ECM. We will read the unique security data from your old module and write it to the replacement one. We will contact you with shipping instructions after your purchase.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the ECM, then yes, this part will resolve the issue. However, if the light is caused by a separate faulty sensor or component on the vehicle, you will still need to address that issue. This pre-programmed 2010-2011 Cadillac STS ECM ensures the vehicle’s ‘brain’ is functioning perfectly.
Is this a new or used part?
This is a high-quality, fully tested replacement Engine Control Module that has been meticulously inspected to meet or exceed original equipment specifications. It is prepared with the latest software for your vehicle to ensure long-term reliability.
