Description
2009 Cadillac XLR-V 4.4L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2009 Cadillac XLR-V 4.4L models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with no dealer visit required.
Built to OEM standards for reliability, calibration accuracy, and long-term performance.
Strict Testing & Quality Assurance
Every ECU is inspected, refreshed, and verified through advanced diagnostic tools. Testing includes:
-
Complete communication & CAN-bus verification
-
Sensor input/output and signal integrity checks
-
Injector & ignition pulse simulation
-
Power, ground, and load-circuit analysis
-
Flash memory integrity and checksum validation
-
Thermal and voltage-stress testing to confirm reliability
This ensures a fully functional, reliable, plug-and-play module you can install with confidence.
Important Note
Some vehicles equipped with IMMO (Immobilizer) or PATS (Passive Anti-Theft System) may require additional key programming after installation. This is normal for models where security data must be synchronized with the vehicle’s body control system.
For a 100% plug-and-play solution with no relearns, no key programming, and no compatibility issues, we recommend our ECU Cloning Service, which transfers all original security, immobilizer, and configuration data directly into the replacement unit.

I was a bit nervous about replacing the ECM on my 2009 Cadillac XLR-V, but this unit arrived perfectly programmed and ready to go. Installation was surprisingly straightforward—just plug it in, and it fired right up without any hiccups. The car runs smoother now, and I haven’t experienced any check-engine lights since. Shipping was quicker than expected, and the seller was super helpful when I had a couple of questions before ordering. Overall, this was a great experience, and I’d definitely recommend this product to anyone needing a reliable ECM replacement.

The ECM arrived quickly and was exactly as described. Installation was straightforward since it was truly plug-and-play, and the VIN programming was spot on with no issues. After switching it in, my XLR-V fired right up and runs smooth. The seller also provided clear instructions, which made the whole process hassle-free.
