Restore Peak Performance to Your 2008 Cadillac Escalade ESV
The Engine Control Module (ECM), often called the Powertrain Control Module (PCM), is the central computer of your 2008 Escalade ESV. It meticulously manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When this critical component begins to fail, it can cause a cascade of frustrating and potentially damaging issues, leaving your luxury SUV running poorly or not at all. This replacement ECM, part number 12617568, is the definitive solution to restore your vehicle’s factory performance, reliability, and efficiency.
Unlike a generic part from a local store, this module is not just a piece of hardware. It’s a complete, plug-and-play solution. We professionally program the unit with the latest official GM software updates specifically for your vehicle using the VIN you provide. This critical step ensures seamless communication with all other modules in your Escalade, eliminating compatibility errors and the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2008 Yukon Denali (which uses this same ECM) come into the shop with a persistent P0300 random misfire code. The owner had already replaced all the spark plugs, wires, and coils. He was convinced the engine was failing. After checking fuel pressure and for vacuum leaks, we hooked up our scope to the injector and coil control wires at the ECM. We found the signal for cylinder 4’s injector was erratic. A quick swap with our known-good test ECM confirmed the issue was internal to the original module. A new, properly programmed ECM like this one had the truck running perfectly in under an hour, saving the customer from hundreds more in unnecessary parts and labor.
Is Your Escalade Showing These Symptoms?
A failing ECM can manifest in various ways. If you’re experiencing any of the following issues, a faulty engine computer could be the culprit:
- ✔ Check Engine Light: The most common sign, often with codes related to sensors, misfires, or module communication.
- ✔ Poor Fuel Economy: Incorrect fuel and air calculations lead to wasted gas and reduced MPG.
- ✔ Engine Stalling or Hesitation: The engine may stumble, hesitate during acceleration, or stall intermittently.
- ✔ Rough Idling: Unstable engine RPMs when the vehicle is stopped.
- ✔ No-Start Condition: The engine cranks but refuses to start due to a lack of spark or fuel command from the ECM.
- ✔ Transmission Shifting Problems: The ECM works with the TCM, and a fault can cause harsh shifts, delayed engagement, or incorrect gear selection.
- ✔ Failed Emissions Test: An improperly functioning ECM cannot correctly manage the emissions systems.

Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No. We program the module to your specific VIN before shipping. In most cases, you will only need to perform a simple security relearn procedure, which can be done without special tools and takes about 30 minutes. Instructions are readily available online. A CASE (Crankshaft Position System Variation) relearn may also be required, which can be done with many high-level scan tools.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship the part until we receive your VIN, as the programming is essential for the part to function.
Is this a brand new part from GM?
This is a high-quality, OEM-grade replacement part that has been thoroughly inspected and tested to meet or exceed original specifications. It is programmed with official GM software.
Will this fix my vehicle’s problem?
This part will correct issues directly caused by a faulty ECM. It is crucial to properly diagnose your vehicle’s problem before ordering. This module will not fix issues caused by other faulty components like sensors, wiring, or mechanical failures.
Where is the ECM located on my 2008 Escalade ESV?
On the 2008 Escalade ESV, the ECM is typically located in the engine compartment on the driver’s side, underneath the battery tray.
