Restore Your Cadillac’s Peak Performance
Is your Cadillac XLR suffering from erratic behavior, a persistent check engine light, or frustrating performance issues? The Engine Control Module (ECM) is the sophisticated brain of your vehicle, and when it begins to fail, it can trigger a host of problems that diminish your driving experience. This professionally programmed ECM is the definitive, hassle-free solution to restore the smooth, responsive power you expect from your luxury roadster.
Common Symptoms & Your Solution
A failing ECM can manifest in various ways, often being misdiagnosed as other component failures. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Persistent Check Engine Light: Especially for codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, or rough idling.
- Reduced Fuel Economy: The engine may run too rich or too lean, causing a sudden drop in MPG.
- Intermittent Stalling: The vehicle may stall for no apparent reason, either while driving or at a stop.
- No-Start Condition: In severe cases, the ECM can fail completely, preventing the engine from starting at all.
This pre-programmed 2006 Cadillac XLR ECM 12602044 is the direct solution to these issues. By providing your vehicle’s VIN at checkout, you receive a unit that is ready for immediate installation, bypassing the need for expensive dealership programming and getting you back on the road faster.

An Expert’s Insight: As a technician with over two decades of experience, I’ve seen countless drivers chase symptoms without addressing the root cause. For vehicles of this era, a failing ECM is often the culprit behind a cascade of confusing electronic issues. Simply swapping a used module won’t work due to anti-theft systems and vehicle-specific programming. Our process of programming this 2006 Cadillac XLR ECM 12602044 to your exact VIN isn’t just a convenience—it’s the only way to ensure every system, from the engine to the transmission, communicates correctly, just as the engineers intended.
Frequently Asked Questions
Do I need to do any programming myself?
No. This ECM comes fully programmed to the VIN you provide during checkout. It is designed for a plug-and-play installation, requiring no additional flashing or programming on your end.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive your VIN, as it is essential for the programming process.
Is this a direct fit for my vehicle?
Yes, this part is a direct replacement for the original ECM on all models listed in the compatibility chart. It replaces numerous GM service numbers, making it a versatile and reliable solution for your specific 2006 Cadillac XLR ECM 12602044 and many other vehicles.
What happens if I install it without providing a VIN?
The module will not function correctly. It will likely prevent the vehicle from starting due to the anti-theft system (VATS) and will not have the correct software for your engine and transmission. Providing the VIN is a mandatory step for a successful repair.
What common problems does this ECM fix?
This module is the solution for a wide range of issues including, but not limited to, check engine light codes P0601-P0606, unexplained stalling, rough idle, poor acceleration, and incorrect automatic transmission shifting.
Will this fix my specific check engine light code?
While this ECM is the definitive fix for internal module failure codes (like P0601), it’s crucial to properly diagnose your vehicle. If the code is for a specific sensor or external component, that part will also need to be addressed. This module will solve the problem if the ECM itself is the root cause.
