Is Your Cadillac SRX Running Rough? Get a Reliable, Programmed Solution.
If you’re dealing with a frustrating check engine light, unpredictable stalling, or a vehicle that simply won’t start, a failing Engine Control Module (ECM) is often the culprit. I’ve seen it countless times in my 20+ years in the shop: a perfectly good engine held hostage by a faulty computer. This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s performance and safety. We offer a dependable, cost-effective solution with this fully programmed, used GM ECM, part number 12592124.

From the Shop Floor: A Real-World Diagnosis
“A customer’s 2005 SRX came in last week with a baffling issue: it would randomly lose power and stall at stoplights, but only when the engine was hot. No consistent codes were stored, just a generic U-code for lost communication. The owner had already replaced the fuel pump on another shop’s advice, with no success. After running a full diagnostic, we noticed the 5-volt reference signal from the ECM was dropping intermittently. That tiny voltage drop was enough to shut down critical sensors and cause the stall. We swapped in a programmed ECM, and the problem was solved instantly. Itโs a classic case where the symptoms don’t point directly at the computer, but experience tells you where to look.”
Easy Installation for Your 2004-2006 SRX ECM
You can install this module yourself with basic hand tools. Located in the right-hand (passenger side) front of the engine compartment, it’s a straightforward swap. Follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes for the system capacitors to discharge.
- Locate the ECM: On your 2004-2006 SRX 3.6L, find the module in the front passenger side of the engine bay.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old ECM. Inspect the pins on the harness side for any corrosion or damage. Clean them with electrical contact cleaner if necessary.
- Remove Old Module: Unbolt the old ECM from its mounting bracket and remove it from the vehicle.
- Install New Module: Bolt the new, programmed ECM into place.
- Reconnect Everything: Securely plug the wiring harnesses into the new module. You should hear a ‘click’ as they lock. Reconnect your battery terminal.
- Final Step: Your vehicle may require a security relearn procedure, which can typically be done by cycling the key. The vehicle is now ready to start.
