An Expert’s Note on VIN Programming
“In modern luxury vehicles like your Cadillac, the ECM is the central command center, communicating with dozens of other modules. Simply installing a non-programmed or incorrectly programmed unit can cause a cascade of issues, from transmission malfunctions to security system lockouts. Our mandatory VIN-programming service isn’t just a convenience; it’s a critical step to ensure every component communicates correctly, preserving your vehicle’s integrity and performance. We take this step to guarantee the repair is done right the first time.”

Frequently Asked Questions
How do I provide my VIN number?
You can add your VIN to the ‘notes’ section during checkout. If you forget, don’t worry! We will contact you via email after your purchase to request the information needed to program your module.
Is any additional programming required after installation?
In most cases, no. Our service makes the unit plug-and-play. For some vehicles, a simple ‘CASE Relearn’ or ‘Crankshaft Variation Relearn’ may be needed, which can be performed by most professional scan tools.
Will this fix my car’s specific problem?
This 2010-2011 Cadillac STS ECM is the solution for a wide range of engine management and performance issues. However, we always recommend having a qualified technician perform a complete diagnosis to confirm the ECM is the point of failure before ordering.
What if I own a Camaro or LaCrosse?
Due to the security system (immobilizer) on these models, we require your original ECM to transfer the security data to the replacement unit. After you place your order, we will provide you with instructions on how to send your old module to us. This ensures the new part will start the car without any issues.
How long does the programming and shipping process take?
Programming is typically completed within one business day of receiving your VIN. Shipping time then depends on the method you select at checkout. We strive to get your vehicle back on the road as quickly as possible.
