Restore Your Escalade’s Power and Reliability
Is your 2007 Cadillac Escalade ESV running rough, stalling, or showing a persistent Check Engine Light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s performance. A faulty ECM can lead to frustrating drivability issues, poor fuel economy, and even a no-start condition. This replacement Engine Control Module, part number 19210738, is the definitive solution to restore your vehicle’s factory performance and operational integrity.
The Brain of Your Vehicle, Delivered Ready to Install
The ECM is arguably one of the most critical components in your truck. It precisely controls fuel injection, ignition timing, transmission shifting, and emissions systems based on data from dozens of sensors. When it fails, the entire system is compromised. We take the guesswork and hassle out of the replacement process. Unlike a generic module from a parts store or salvage yard, this unit is professionally programmed specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and we will flash the module with the latest, most stable GM factory software updates. This ensures seamless integration and optimal performance right out of the box, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2007 Tahoe come in with a bizarre, intermittent misfire on cylinder 3. The owner had already replaced the spark plug, ignition coil, and even the fuel injector, but the problem persisted. Standard diagnostics showed no obvious cause. After hooking up our professional scan tool and monitoring live data, we noticed the injector pulse width for cylinder 3 was erratic under load. Suspecting the driver circuit within the computer, we swapped in a known-good, properly programmed ECM. The misfire vanished instantly. The original ECM had an internal failure that was impossible to see without deep-level diagnostics, a common end-of-life issue for these modules. This highlights why replacing a faulty 2007 Escalade ESV ECM with a correctly programmed unit is often the final, correct fix.
Symptoms of a Failing 2007 Escalade ESV ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Unexplained drop in fuel economy.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Rough or erratic idling.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Loss of power and poor overall engine performance.
- ✔ Communication errors with diagnostic scan tools.
Guaranteed Compatibility and Simple Installation
This module is a direct replacement for a wide range of GM vehicles from the 2007 model year and is a direct cross-reference for part numbers 12589297, 12597121, 12603892, and 19210738. On the 2007 Escalade ESV, the ECM is conveniently located in the engine bay on the driver’s side, under the battery. Installation is straightforward for a competent DIY mechanic: simply disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Once the new module is connected and the battery is reconnected, your vehicle is ready to go. In some cases, a simple security relearn procedure may be required, which can be done without special tools.
Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We handle all the programming for you before shipment. We use your vehicle’s VIN to load the correct GM factory software and updates, so it arrives ready for installation.
Where is the ECM located on my 2007 Escalade ESV?
The Engine Control Module is located in the engine compartment on the driver’s side (LH side), underneath the battery tray.
Is any additional setup required after I install the module?
In most cases, the vehicle will start and run perfectly after installation. Occasionally, a Crankshaft Variation Relearn (CASE Relearn) or a security relearn procedure may be necessary to clear certain trouble codes. This can often be performed by a local mechanic with a capable scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you can send us a message with your 17-digit VIN. Alternatively, you can add it as a note to your order during the checkout process.
Will this part fix my specific problem?
This ECM will resolve issues directly caused by a faulty engine computer. While the symptoms listed are very common for ECM failure, it’s always recommended to have a proper diagnosis performed to rule out other potential causes like sensor or wiring problems.
