Is Your Cadillac SRX Running Rough?
If you’re experiencing frustrating issues like a persistent check engine light, poor fuel economy, engine stalling, or erratic shifting, the root cause is often a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel injection and ignition timing to emissions control and transmission function. When it begins to fail, it can create a cascade of problems that are difficult to diagnose and can make your vehicle unreliable.
This is a direct-fit replacement Engine Control Module for your 2010-2011 Cadillac SRX. We take the guesswork out of the repair by pre-programming the unit specifically to your vehicle’s Vehicle Identification Number (VIN). This ensures that it communicates perfectly with all other modules in your car, restoring its original performance and reliability. Simply provide us with your VIN after purchase, and we’ll load the latest, most stable software from GM before shipping it to you.
From the Diagnostic Bay
We had a 2011 SRX in the shop that was driving the owner crazy. It had a random misfire code (P0300) and would occasionally hesitate under acceleration. The owner had already replaced the spark plugs, ignition coils, and even a fuel injector with no success. After hooking up our diagnostic scanner, we noticed the fuel trim data was erratic, but all sensor readings seemed plausible. On a hunch, we monitored the injector driver signals directly from the ECM and found that the signal for cylinder 3 was intermittently dropping out. The problem wasn’t a bad injector; it was a failing driver inside the original ECM. We installed one of our VIN-programmed modules, and the SRX ran perfectly. It’s a classic case of how a faulty computer can mimic mechanical failures, costing you time and money on unnecessary parts.
Common Symptoms of a Failing 2010-2011 SRX ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Engine misfires, stumbles, or runs rough at idle.
- ✔ Unexplained drop in fuel mileage.
- ✔ Vehicle stalls unexpectedly while driving or at a stop.
- ✔ Harsh or delayed transmission shifting.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Loss of communication with the OBD-II port, making diagnostics impossible.
- ✔ Error codes related to processor failure, memory issues, or sensor reference voltage.

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN is essential for programming the ECM. It contains specific information about your car’s engine, transmission, and factory-installed options. Programming with the VIN ensures the module works seamlessly with your vehicle’s systems, just like the original part from the factory.
Is this part difficult to install?
The physical installation is typically straightforward. The ECM is usually located in the engine compartment and is secured by a few bolts and electrical connectors. However, you should always disconnect the battery before starting work. If you are not comfortable working on your vehicle’s electrical system, we recommend professional installation.
Will this ECM require additional programming at the dealer?
No. This module is shipped fully programmed to your VIN with the latest GM software. It is designed to be a plug-and-play solution, eliminating the need for an expensive trip to the dealership for programming.
How do I find my original part number?
The part number is printed on a sticker on the case of your current ECM. You will need to locate the module in your vehicle’s engine bay and read the number directly from the label to confirm a match.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to properly diagnose the problem first. This module will not fix issues caused by faulty sensors, wiring, or other mechanical components.
