Restore Peak Performance to Your Cadillac SRX
Is your 2012 Cadillac SRX suffering from baffling issues like a persistent check engine light, poor fuel economy, stalling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine performance. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leading to a frustrating and unreliable driving experience. This pre-programmed ECM is the definitive solution to get your luxury crossover running like new again.
From the Diagnostic Bay
We had a 2012 Cadillac CTS with the 3.6L engine come into the shop with a complaint of intermittent stalling and a flashing check engine light that no one could solve. The owner had already replaced spark plugs and a coil pack. After hooking up our professional scan tool, we noticed communication dropouts with the engine module. We suspected the ECM was failing internally, causing these ghost-like issues. Instead of a costly trip to the dealer for a new module and programming, we sourced this exact pre-programmed unit. After a straightforward installation and a quick security relearn, the CTS ran perfectly. The intermittent stalls vanished, and the owner was thrilled to have their car back without the massive dealership bill. This is the same reliable solution we offer you today.
Is Your Vehicle Showing Signs of ECM Failure?
- ✔ Persistent Check Engine Light: The light stays on despite other repairs, often with communication-related error codes (U-codes) or performance codes.
- ✔ Engine Performance Issues: You may experience random misfires, rough idling, hesitation during acceleration, or a noticeable loss of power.
- ✔ Reduced Fuel Economy: A failing ECM can’t properly regulate the air-fuel mixture, causing your vehicle to consume more gasoline than usual.
- ✔ Transmission Problems: The ECM communicates with the transmission controller. A fault can lead to harsh shifting, delayed engagement, or getting stuck in a single gear.
- ✔ Intermittent or Total No-Start: The most severe symptom is the engine refusing to crank or start, as the ECM controls the ignition and fuel systems.
- ✔ Unexplained Electrical Issues: Because the ECM is a central network hub, its failure can sometimes cause other warning lights or strange behavior from vehicle electronics.

Instructions are readily available online, or a local mechanic can perform it quickly. This process saves you hundreds of dollars in dealership programming and labor fees.
Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module for you before it ships. All you need to do is provide your vehicle’s VIN when you place your order. It arrives ready for installation.
What is a security relearn procedure?
A security relearn, or key relearn, is a simple process that syncs the new ECM with your vehicle’s existing anti-theft system and keys. For most GM vehicles of this era, it involves turning the key to the ‘ON’ position for 10 minutes, off for 10 seconds, and repeating this cycle three times. This allows the components to recognize each other.
Where do I find my vehicle’s VIN?
Your 17-digit VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
How can I be sure the ECM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis from a qualified mechanic is always recommended. Common diagnostic trouble codes pointing to a bad ECM include P0600-P0606, or U-series codes indicating a loss of communication. A mechanic can also test the power and ground circuits to the ECM to rule out wiring issues.
Does this part fit vehicles other than the 2012 Cadillac SRX?
Yes. This ECM is compatible with a wide range of GM vehicles from roughly 2012-2016, including models like the Buick LaCrosse, Chevy Camaro, GMC Acadia, and Cadillac CTS. Please refer to the detailed fitment list on this page to confirm compatibility with your specific make, model, and year.
