Is Your Cadillac SRX Plagued by Engine Problems?
If you’re dealing with a persistent check engine light, rough idling, stalling, or even a no-start condition in your 2004-2006 Cadillac SRX, a failing Engine Control Module (ECM) is a very likely culprit.

You’re not just buying a part; you’re buying a solution to get your luxury SUV running smoothly again.

This means no expensive trips to the dealership for programming or key relearning procedures.

Real-World Diagnostic Story
“A customer’s 2005 SRX came in last week with a persistent misfire code for cylinder 4 (P0304) that wouldn’t go away. They had already replaced the coil and spark plug twice. We checked the wiring and injector pulse with a noid light, which seemed weak. Instead of just replacing the injector, we scoped the driver circuit directly at the ECM connector. The signal was degraded. After installing one of our pre-programmed ECMs, the misfire was gone instantly. The original ECM’s injector driver had failedโa common issue on these units that often gets misdiagnosed.”
Simple, Straightforward Installation
You don’t need to be a master technician to replace your 2004-2006 SRX ECM. With basic tools, you can have your vehicle back on the road in under an hour. The ECM on the SRX is conveniently located in the right-hand (passenger side) front of the engine compartment.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to discharge.
- Locate the ECM: Open the hood and find the ECM on the passenger side of the engine bay. It’s a silver metal box with several large electrical connectors.
- Disconnect Connectors: Carefully release the locking tabs on the electrical harnesses and pull them straight out from the module. Never force them. Inspect the pins for any corrosion or damage.
- Remove the Old Module: Unbolt the mounting hardware holding the original ECM in place and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed ECM in the same location and secure it with the original hardware.
- Reconnect Everything: Firmly plug the electrical connectors back into the new ECM until they click into place. Reconnect the negative battery terminal.
- Final Check: Start the engine. The check engine light should be off, and the engine should run smoothly. Your SRX is ready to drive!
