Restore Peak Performance to Your Cadillac
Is your 2007 Cadillac Escalade ESV running rough, stalling unexpectedly, or showing a persistent check engine light? These are common indicators of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine performance, fuel economy, and emissions. A faulty ECM can lead to a cascade of frustrating and potentially damaging issues. This direct-fit replacement ECM, part number 12603892, is the definitive solution to get your luxury SUV back on the road with the reliability and power you expect.
Unlike generic modules that require expensive dealership programming, this unit is meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. We load the latest, most stable software updates from GM, ensuring optimal communication between all vehicle systems and correcting many common factory drivability issues. This VIN-specific programming makes installation straightforward, restoring your engine’s original factory settings and performance characteristics.
From the Diagnostic Bay
We had a 2007 Tahoe come in with a bizarre complaint: it would randomly stall at stoplights, but only when the A/C was on. No codes were stored initially. After hours of chasing wiring and testing sensors, we finally caught the ECM dropping communication with the throttle body for a split second. The internal processor was failing under the specific load conditions. We installed a VIN-programmed module just like this one, performed the security relearn, and the problem was gone for good. It’s a classic example of how a failing ECM can create symptoms that seem unrelated to the computer itself.
Is Your 2007 Escalade ESV ECM Failing?
The ECM is the brain of your engine’s operation. When it begins to fail, the symptoms can range from subtle annoyances to critical failures that leave you stranded. Look out for these common warning signs:
- ✔ Check Engine Light: The most obvious sign, often with codes related to sensors, communication errors (U-codes), or processor faults.
- ✔ Engine Stalling or Misfiring: The engine may stall for no reason, run rough, or misfire as the ECM fails to correctly manage fuel and spark.
- ✔ No-Start Condition: Your Escalade may crank but refuse to start if the ECM isn’t activating the fuel pump or ignition coils.
- ✔ Poor Fuel Economy: An inefficiently running engine, managed by a failing ECM, will almost always result in a noticeable drop in MPG.
- ✔ Shifting Problems: The ECM communicates with the transmission controller. Faulty signals can lead to harsh or erratic shifting.
- ✔ Inconsistent Performance: You might experience sudden loss of power, hesitation during acceleration, or other unpredictable engine behavior.

This ensures all onboard systems, from the anti-lock brakes to the climate control, function in harmony with the engine. This module is a direct replacement for multiple part numbers, including 12589297, 12597121, 12603892, and 19210738, making it a versatile and reliable choice for a wide range of GM trucks and SUVs.
Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No. This ECM comes fully programmed to your vehicle’s VIN with the latest GM software updates. However, you will likely need to perform a security relearn procedure (also known as a key relearn or anti-theft relearn). This can typically be done without special tools and involves a sequence of key turns. Instructions are widely available online for your specific vehicle.
Where is the ECM located on my 2007 Escalade ESV?
On the 2007 Cadillac Escalade ESV, the Engine Control Module is typically located in the engine bay, on the driver’s side, underneath the battery tray.
Is this a new or used part?
This is a high-quality, inspected, and tested original equipment part that has been prepared for your vehicle. Each unit is verified for full functionality before being programmed and shipped.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. Your VIN can be found on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
Will this fix my specific problem?
While this ECM will resolve issues caused by a faulty module, it’s crucial to ensure your vehicle has been properly diagnosed. A failing ECM can mimic other problems, such as a bad sensor or wiring issue. We recommend a thorough diagnosis by a qualified technician to confirm the ECM is the point of failure.
