Frequently Asked Questions
Do I need to do any extra programming myself?
No. This PCM comes fully programmed to the VIN you provide. In most cases, it is a direct installation. However, some vehicles may require a security relearn procedure, which is a simple process that can typically be done without special tools. We can provide instructions for this if needed.
Where do I provide my vehicle’s VIN?
After completing your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically reply to your order confirmation email or send it through the platform’s messaging system. We cannot ship your part until we receive the VIN.
How do I know this will fit my specific Cadillac?
This 2004-2006 Cadillac 4.6L PCM 12576523 is compatible with the SRX (04-06), STS (05-06), and XLR (04-06) models equipped with the 4.6L engine. The most accurate way to confirm is by matching the part number 12576523 on your original unit. Programming to your VIN further guarantees electronic compatibility.
What if my original PCM has a security system?
Our programming process takes your vehicle’s factory anti-theft system (like VATS or Passlock) into account. By using your VIN, we ensure the module is correctly configured to communicate with your car’s security components, which simplifies the installation process significantly.
Is a Crankshaft Variation Relearn necessary?
For optimal performance and to prevent certain trouble codes, a Crankshaft Variation Relearn (also known as a CASE relearn) is often recommended after replacing a PCM. This procedure can be performed by most professional scan tools and helps the new computer synchronize perfectly with your engine’s sensors.
