An Expert’s Note on Installation
As a technician, I’ve seen countless ECM replacements. The number one key to a successful swap is providing the correct VIN. Double-check it before sending it to us. Once you receive your part, disconnect the battery before unplugging the old module. After installing the new one and reconnecting the battery, you may need to perform a simple security relearn procedure (often called a ‘key-on/key-off’ cycle), which you can find in your owner’s manual or online. This simple step ensures your vehicle’s anti-theft system recognizes the new module, preventing no-start issues.
Don’t let a faulty computer compromise the performance and safety of your vehicle. This programmed 2006 Cadillac STS ECM 12630457 is the most reliable and efficient way to get your car running like new again. Order today and experience the difference a perfectly functioning engine computer makes.
Frequently Asked Questions
Do I need to get this ECM programmed?
No. This module comes pre-programmed to your vehicle’s specific VIN. Simply provide us with your VIN at checkout, and we handle all the flashing and software updates before shipping the part to you.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this a difficult part to install?
For someone with moderate mechanical skill, installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and then reversing the process with the new unit. On the 2006 STS, it is located on the LH frame rail. However, we always recommend professional installation if you are not comfortable with automotive repair.
Will this fix my specific problem?
This ECM is a direct solution for issues caused by a faulty engine computer. While it corrects a wide range of symptoms, including check engine lights and performance problems, it’s crucial to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
What is a security relearn procedure?
A security relearn, or anti-theft relearn, is a simple procedure that syncs the new ECM with your vehicle’s existing keys and security system. It usually involves a sequence of turning the key to the ‘ON’ position for about 10 minutes, then ‘OFF’, and repeating a few times. This is often necessary to allow the vehicle to start after the new module is installed.
