Is Your Cadillac CTS or GM 3.6L Running Rough? The ECM Might Be the Culprit.
n
If you’re grappling with persistent check engine lights, erratic engine behavior, or a no-start condition in your 2008-2009 Cadillac CTS, Pontiac G8, or other compatible GM vehicle, the root cause is often a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, orchestrating everything from fuel injection and ignition timing to transmission shifts and emissions control. When it begins to fail, it can create a cascade of frustrating and difficult-to-diagnose problems. This isn’t just an inconvenience; it affects your vehicle’s performance, fuel economy, and reliability.
nn
This listing offers a reliable and cost-effective solution: a genuine, used OEM Engine Control Module, part number 12619582 (also compatible with 12623327 and 12614423). We take the guesswork and high dealership costs out of the equation. Before we ship the part, our technicians will program it specifically to your vehicle using the VIN you provide. This ensures that the module communicates perfectly with your car’s existing systems, making for a straightforward installation process.

From the Diagnostic Bay
n
We recently had a 2008 Cadillac SRX with the 3.6L engine come into the shop. The owner had spent a small fortune replacing the throttle body, all six ignition coils, and the mass air flow sensor, yet the car still stalled intermittently and had a persistent P0606 (ECM Processor Fault) code. The check engine light was his constant companion. After confirming power and ground to the module were solid, we knew the internal processor was failing. Instead of a multi-thousand dollar bill from the dealer for a new unit and programming, we sourced a tested, used module like this one. We programmed it to the SRX’s VIN, performed the security relearn, and the vehicle ran like new. The owner was thrilled to finally have a reliable car again without breaking the bank. It’s a classic case of chasing symptoms when the core problem lies with the vehicle’s brain.

Diagnosing a Faulty 2008-2009 CTS ECM
n
A failing ECM can manifest in numerous ways, often mimicking other sensor or component failures. If you’re experiencing several of the following issues, it’s a strong indicator that your engine computer needs attention. This module is the correct solution for these common problems.
n
- n
- ✔ Check Engine Light: The most common symptom, often with communication-related codes (U-codes) or internal processor fault codes (P06xx series).
- ✔ Engine Stalling or Misfiring: The engine may stall for no apparent reason, either while driving or at idle. You may also experience random misfires that don’t seem tied to a specific coil or plug.
- ✔ No-Start Condition: The engine cranks but refuses to start. This can happen if the ECM is not properly controlling the fuel injectors or ignition system.
- ✔ Poor Fuel Economy: An improperly functioning ECM can lead to inefficient fuel mixture calculations, causing a noticeable drop in your MPG.
- ✔ Harsh or Incorrect Shifting: The ECM works in tandem with the Transmission Control Module (TCM). A faulty ECM can send incorrect data, leading to poor automatic transmission performance.
- ✔ Intermittent Electrical Issues: Seemingly unrelated problems, like cooling fans not turning on or erratic gauge behavior, can sometimes be traced back to a failing ECM.

Installation Process
n
Once you receive your pre-programmed ECM, the physical installation is typically straightforward. The ECM is located in the engine compartment (RH side for CTS/SRX, LH side for Equinox/Torrent). Disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. After reconnecting the battery, you may need to perform a simple ‘Security Relearn’ or ‘Key Relearn’ procedure, which pairs the new ECM to your vehicle’s anti-theft system. This procedure can usually be done without special tools and instructions are widely available online or in service manuals.

Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM) is your car’s main computer. It controls the engine’s fuel delivery, spark timing, emissions systems, and communicates with other vehicle modules to ensure everything operates smoothly.
Is this part ready to install when it arrives?
Yes! We program the module to the VIN you provide during checkout. This means it arrives ready for physical installation. In some cases, a simple key relearn procedure may be required after installation, which does not require a scanner.
How do I provide my Vehicle Identification Number (VIN)?
You can add your 17-digit VIN to the notes section during checkout or send it to us in a message after your purchase. We cannot ship the part until we have your VIN to program it correctly.
My original part number is 12614423. Will this part work?
Yes, it will. This ECM, part number 12619582, is a direct supersession and is compatible with older part numbers like 12614423 and 12623327 for the listed vehicles. We program it to function identically to your original.
Is this a new part?
No, this is a thoroughly tested, genuine OEM part that has been sourced from a salvaged vehicle. This provides OEM quality and reliability at a fraction of the cost of a new unit from the dealer.
What is a security relearn procedure?
It’s a simple process that syncs the new ECM with your car’s anti-theft system and keys. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating the cycle two more times. This allows the systems to recognize each other.
