Is Your Cadillac SRX Running Rough? Get a Reliable Solution.
If you’re dealing with a persistent check engine light, poor fuel economy, stalling, or a no-start condition in your 2004-2006 Cadillac SRX, a failing Engine Control Module (ECM) is a very likely culprit. As the brain of your vehicle’s engine, when the ECM starts to fail, it can create a cascade of frustrating and hard-to-diagnose problems. This isn’t just a part; it’s the command center for your engine’s performance and reliability.
This listing is for a thoroughly tested, used genuine GM Engine Control Module, part number 12592124. We take the guesswork and high cost out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures it communicates perfectly with your SRX’s other systems right out of the box.
Common Symptoms of a Failing GM 3.6L ECM:
- โ Persistent Check Engine Light (CEL) with various communication or sensor codes.
- โ Engine stalling, stumbling, or hesitating during acceleration.
- โ Unexplained drop in fuel mileage.
- โ Harsh or erratic automatic transmission shifting.
- โ Complete no-start condition where the engine cranks but won’t fire up.
- โ Communication errors with diagnostic scan tools.
From the Shop Floor: A Real-World Diagnosis
“A customer’s 2005 SRX came in last month with a baffling issue. It would intermittently stall at stoplights and had a P0601 (Internal Control Module Memory Check Sum Error) code that would come and go. The owner had already replaced two coil packs and the throttle body based on another shop’s advice, with no improvement. After confirming solid power and ground to the ECM, we knew the internal processor was failing. We installed one of our VIN-programmed modules, and the vehicle has been running flawlessly since. It’s a classic case where chasing symptoms instead of the root cause gets expensiveโthe ECM was the problem all along.”
Why a Pre-Programmed 2004-2006 SRX ECM is the Smart Choice
Getting a new ECM from a dealership often involves multiple appointments, high labor costs for programming, and a hefty price tag for the part itself. Our solution simplifies the entire process. By sending us your VIN during checkout, you receive a module that is loaded with the latest GM software updates for your exact vehicle. This not only restores function but can also correct factory drivability issues you might not have even known about.
Plug-and-Play Installation: No Dealer Visit Required
While professional installation is always recommended, this part is designed for a straightforward swap. Here are the general steps for replacing the ECM on your SRX:
- Safety First: Disconnect the negative battery terminal and wait 10 minutes for the system capacitors to discharge.
- Locate the ECM: On the 2004-2006 SRX, the ECM is typically located in the right-hand (passenger side) front of the engine compartment.
- Disconnect Connectors: Carefully release the locking tabs and disconnect the electrical wiring harnesses from the old module. Inspect the connectors for any corrosion or bent pins.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed ECM and securely reconnect the wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Security Relearn (If Necessary): In some cases, a simple 10-minute key-on/key-off security relearn procedure may be required. Your vehicle’s service manual can provide the exact steps.
