Restore Peak Performance to Your Cadillac SRX
Is your 2010-2011 Cadillac SRX suffering from frustrating and unpredictable issues? A flashing check engine light, poor fuel economy, stalling, or a complete no-start condition can often be traced back to a single, critical component: the Engine Control Module (ECM). As the ‘brain’ of your vehicle’s engine, the ECM is responsible for managing everything from fuel injection and ignition timing to emissions controls. When it fails, the symptoms can be maddening and difficult to diagnose. This is the reliable, straightforward solution you’ve been searching for.
This isn’t just a replacement part; it’s a complete resolution. We provide a genuine GM Engine Control Module that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures that the module communicates perfectly with your SRX’s existing systems, incorporating all the latest software updates from GM. You get a part that is truly ready for installation, saving you a costly trip to the dealership for programming.
Case Study: A Tricky Diagnosis
I remember a 2011 SRX 3.0L that came into my shop with a complaint of intermittent stalling at stoplights and a persistent U0100 ‘Lost Communication with ECM/PCM’ code. The owner had already replaced the battery and checked all the main power and ground connections. We spent hours tracing wires, looking for a phantom short. On a hunch, after seeing no other logical cause, we connected a known-good ECM. The problem vanished instantly. The original ECM’s internal processor was failing under thermal load, causing it to randomly drop communication. This pre-programmed module is the exact fix for that kind of deep-seated electronic issue.
Is Your Cadillac SRX Showing These Signs?
A failing ECM can manifest in numerous ways. If you’re experiencing any of the following, a faulty engine computer is a likely culprit:
- ✔ Unexplained Check Engine Light (CEL) with codes like P0601, P0606, or communication errors.
- ✔ Engine cranks but refuses to start.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Other warning lights on the dash, like traction control, due to communication failures.
A Straightforward Guide to Installation
Replacing the ECM on your SRX is a manageable task for a confident DIYer. Our pre-programmed module simplifies the process significantly. Always consult a vehicle-specific repair manual, but here is a general guide:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow all systems to discharge.
- Locate the ECM: On the 2010-2011 SRX, the ECM is typically found in the engine compartment on the driver’s side (LH side).
- Disconnect Connectors: Carefully release the locking tabs and disconnect the electrical wiring harnesses from the old ECM. Inspect the connectors for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed ECM securely onto the bracket.
- Reconnect and Secure: Firmly plug the wiring harnesses into the new ECM until they click into place. Reconnect the negative battery terminal.
- Security Relearn Procedure: After installation, you may need to perform a security relearn procedure (often called a Passlock or Passkey relearn) to allow the vehicle to start. This procedure typically involves cycling the key in the ignition and can be done without special tools. Instructions are widely available online or in your owner’s manual.

Frequently Asked Questions
What does ‘VIN Programmed’ mean?
It means we load the module with the specific software and calibrations for your exact vehicle using your VIN. This ensures all factory options and security systems work correctly, just like a new module from the dealer, but without the extra cost and hassle of programming it yourself.
Do I need to do anything after installing this 2010-2011 SRX ECM?
After physical installation, you will likely need to perform a simple security relearn procedure. This procedure pairs the new ECM to your vehicle’s anti-theft system and can be done at home by cycling the ignition key. No special scan tools are required.
How do I send you my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
Is this a guaranteed fix for my car’s problems?
This ECM will correct any issues directly caused by a faulty engine computer. While the symptoms listed are very common for ECM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the root cause before ordering.
Where is my old part number located?
The part number is printed on a sticker on the case of your original ECM. You may need to remove the module to see it clearly. Matching it to one of the numbers in our listing confirms compatibility.
