An Expert’s Note on Installation & Security
Today’s vehicles feature advanced anti-theft systems, and the ECM is a core component. After installing this new module, a ‘Vehicle Theft Deterrent (VTD) Relearn’ procedure may be required to sync the computer with your car’s keys and security system. This is a standard, necessary step for most modern GM vehicles to ensure security integrity. We highly recommend that installation and any required relearn procedures are performed by a qualified automotive technician with access to professional tools like GM’s Tis2web or Techline Connect. This ensures the job is done right, protecting your investment and getting you back on the road without a hitch.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program or ship your module without it.
Is this module ready to install right out of the box?
Yes, it arrives fully programmed to your VIN. However, as a standard security measure, you or your mechanic will need to perform the VTD (theft) relearn procedure after installation so the vehicle will start. Other vehicle-specific relearns, like for the crankshaft position sensor, may also be necessary.
Who should install this part?
We strongly recommend installation by a certified automotive technician who has experience with modern vehicle electronics and access to the appropriate diagnostic and programming tools to perform any necessary relearn procedures.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, this part will resolve the issue. It’s crucial that the vehicle is properly diagnosed before purchase to confirm the original ECM is the source of the problem. This module will not fix issues related to other faulty sensors or mechanical components.
Does this part fit vehicles other than the Cadillac ATS?
Yes, this ECM is compatible with a wide range of GM vehicles, including the Escalade, Silverado 1500, Sierra 1500, Tahoe, Yukon, Corvette, and various CTS models. Please verify your original part number matches one of the numbers listed to ensure compatibility.
What is a ‘theft relearn’ procedure?
It’s a simple process that synchronizes your new ECM with your vehicle’s existing keys and security system. Without this step, the security system will prevent the engine from starting. This is a standard procedure for any ECM replacement on these vehicles.
