Restore Your Cadillac’s Flawless Performance
Is your 2009 Cadillac SRX suffering from frustrating and unpredictable issues? A flashing check engine light, sudden stalling, rough idling, or a complete failure to start can ruin the driving experience you expect from a luxury vehicle. These are classic signs of a failing Engine Control Module (ECM), the electronic brain of your vehicle. Don’t let a faulty computer compromise your safety and peace of mind. This replacement ECM is the definitive solution, arriving pre-programmed and ready to restore the smooth, powerful, and reliable operation your Cadillac was designed for.
Common Symptoms & Your Solution
A failing ECM can manifest in numerous ways, often leading to confusing diagnostics. If you’re experiencing any of the following, this module is your answer:
- Persistent Check Engine Light: Especially for codes like P0601, P0602, P0606, or other internal controller errors.
- Engine Performance Issues: Unexplained stalling, rough running, hesitation during acceleration, or a noticeable drop in fuel economy.
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel or spark signals from the ECM.
- Erratic Transmission Shifting: The ECM plays a key role in communicating with the transmission controller, and a fault can cause harsh or improper gear changes.
This isn’t just a replacement part; it’s a comprehensive fix. We take the guesswork out of the repair by programming the unit specifically to your vehicle’s VIN before it ever leaves our facility. This ensures that your new 2009 Cadillac SRX ECM communicates perfectly with all other systems, just as the original did from the factory.

Expert Insight: The Critical Role of VIN-Specific Programming
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched electronics. Simply installing a used ECM from another vehicle rarely works. Modern vehicles have complex security and communication networks (like GM’s GMLAN) that require modules to be perfectly synchronized. Our VIN-programming service isn’t just a convenience; it’s a critical step. We ensure the Immobilizer (anti-theft) data, injector flow rates, and specific calibrations for your SRX’s 4.6L engine are loaded correctly. This prevents compatibility conflicts and guarantees a successful, lasting repair the first time.
Frequently Asked Questions
Do I need to send you my old ECM?
No, there is no core charge or requirement to send your old module to us. This helps you get your vehicle back on the road faster.
What is the programming process?
After you place your order, you provide us with your vehicle’s 17-digit VIN. We use this number to access the official GM database and download the exact software calibration for your specific vehicle. We then flash this software onto the ECM before shipping it to you.
Will this fix my specific check engine light codes?
This module is the correct solution for internal processor failure codes (like P0601, P0606) and other communication-related faults originating from the ECM. While it can resolve many performance-related codes, it’s crucial to ensure other vehicle components (sensors, wiring) have been properly diagnosed first.
Is any additional programming needed after installation?
In most cases, no. Since the unit is pre-programmed to your VIN, it should function immediately. However, some vehicles may require a simple security or crankshaft position sensor (CASE) relearn procedure, which can often be done with a capable scan tool or by following a specific drive cycle.
How do I know if this is the right part for my car?
This 2009 Cadillac SRX ECM is a direct replacement for part number 12630464 and the other service numbers listed. The best way to confirm is to match the part number on your existing module. If you are unsure, please provide us with your VIN, and we can verify compatibility for you.
