Is Your Cadillac SRX Running Rough, Stalling, or Showing a Check Engine Light?
As a technician with over two decades of experience, I’ve seen countless drivers frustrated by mysterious engine problems. Your 2010-2011 Cadillac SRX might be experiencing issues like erratic idling, poor fuel economy, or even a dreaded no-start condition. Often, the root cause isn’t a mechanical failure but a problem with the vehicle’s brain: the Engine Control Module (ECM). When the ECM fails, it can send the entire system into chaos, leaving you stranded and facing a costly trip to the dealership.
This is the direct, reliable solution you’ve been searching for. This Engine Control Module, part number 12650256, is a tested, proven replacement for your original unit. The best part? We handle the most critical step for you. Simply provide your vehicle’s VIN during checkout, and our experts will program the module with the latest GM-certified software specifically for your SRX. It arrives at your door ready to install, eliminating the need for expensive dealership programming or specialized scan tools.
Expert Pro Tip: Check Your Connectors First!
Before you condemn your ECM, take a moment to inspect the main harness connectors that plug into the module. In my shop, I’ve seen SRX and Equinox models of this era develop intermittent issues due to corrosion or backed-out pins in these connectors. A simple cleaning with a quality electronics cleaner and ensuring they are fully seated can sometimes resolve the problem. If the pins look green or damaged, you’ve likely found a contributing factor to the module’s failure.
Common Symptoms of a Failing 2010-2011 SRX ECM
If your vehicle is exhibiting any of these signs, a faulty engine computer is a likely culprit. Replacing it can restore your vehicle’s performance and reliability.
- โ Persistent Check Engine Light (CEL) with various communication or processor codes.

- โ Noticeable decrease in fuel efficiency.

Plug-and-Play Installation: No Dealer Visit Required
You can perform this replacement right in your own driveway. The ECM on the 2010-2011 SRX is located in the engine compartment on the driver’s side. Follow these simple steps for a successful installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post.
- Locate the ECM: Open the hood and find the ECM on the driver’s side, typically near the strut tower or air filter housing.
- Disconnect the Harnesses: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. Do not force them.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware, as you will reuse it.
- Install the New Module: Mount your new, pre-programmed ECM onto the bracket and secure it with the original hardware.
- Reconnect Everything: Plug the electrical harnesses back into the new ECM, ensuring they click securely into place. Reconnect the negative battery terminal.
