Restore Peak Performance to Your Cadillac DTS
Is your 2006 Cadillac DTS suffering from perplexing electrical issues, poor engine performance, or a persistent Check Engine Light? The Engine Control Module (ECM), the brain of your vehicle’s engine management system, is often the culprit. A failing ECM can lead to a cascade of problems that are difficult to diagnose, from rough idling and stalling to a complete no-start condition. This replacement Engine Control Module, part number 12607096, is the definitive solution to restore your vehicle’s reliability and drivability.
Unlike sourcing a used module from a junkyard, which would require expensive and time-consuming dealership programming, this unit arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest GM-certified software updates, ensuring optimal performance, fuel efficiency, and emissions control. This process makes installation straightforward, eliminating the need for specialized tools or a trip to the mechanic for programming.
From the Diagnostic Bay
We recently had a 2006 Cadillac DTS in the shop with a mysterious, intermittent misfire on cylinder 3. The owner had already replaced the spark plug, ignition coil, and fuel injector, but the problem persisted. After hours of chasing wires, we hooked up an oscilloscope to the injector control wire at the ECM. We found the signal from the module’s driver was weak and inconsistent. A new, programmed ECM fixed the issue instantly. It’s a classic case where the root cause lies within the vehicle’s central computer, not the components it controls.
Symptoms of a Failing 2006 DTS Engine Module
If you’re experiencing any of the following issues, a faulty ECM could be to blame. Replacing it can resolve these frustrating and potentially damaging conditions.
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough or erratic idling.
- ✔ Vehicle entering ‘limp mode’ with reduced power.
- ✔ Complete no-start or intermittent starting problems.
- ✔ Automatic transmission shifting issues.
- ✔ Communication errors with diagnostic scan tools.
A Seamless, Programmed Solution
This module is a direct replacement for a wide range of GM vehicles and is interchangeable with several service numbers, including 12590032, 12602044, 12603530, and more. The most critical step is the VIN programming. By providing us with your VIN during checkout, you ensure that the module you receive is perfectly matched to your vehicle’s factory specifications, including its engine, transmission, and emissions equipment. This is not a generic, one-size-fits-all part; it is a component prepared specifically for your car.
Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming loads your vehicle’s specific software onto the ECM. This is crucial because it ensures the engine, transmission, anti-theft system (VATS), and other modules communicate correctly. Without it, your vehicle will not start or run properly.
Is this installation difficult? Do I need a mechanic?
For many models, the ECM is in an accessible location (e.g., in the air filter box or on the firewall) and can be swapped with basic hand tools. Since our module comes pre-programmed, you do not need a mechanic for programming. However, some vehicles may require a security relearn procedure, which can typically be done without special tools. We recommend consulting a repair manual for your specific vehicle’s procedure.
How 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 your part until we have this information to complete the programming service.
Will this ECM fix my car’s problem for sure?
This part will correct any issues directly caused by a faulty ECM. While the symptoms listed are very common for ECM failure, we always recommend a proper diagnosis by a qualified technician to confirm the ECM is the point of failure before ordering.
What if my original part number is not 12607096?
This module is a direct replacement for several part numbers, including 12590032, 12602044, 12603530, 12605843, 12630457, and 19210737. As long as your original part number is on this list, this module will work perfectly once programmed to your VIN.
