Restore Your Cadillac’s Performance and Reliability
If your 2006 Cadillac DTS is experiencing baffling issues like stalling, erratic shifting, a persistent Check Engine Light, or a no-start condition, the Engine Control Module (ECM) is a very likely culprit. As the central computer of your vehicle, a failing ECM can cause a cascade of problems that are often misdiagnosed. This isn’t just an inconvenience; it’s a critical failure that compromises your car’s performance and safety. Stop throwing parts at the problem and get to the root cause with a reliable, correctly programmed replacement.
This ECM, part number 12607096, is the direct-fit solution you need. We take the guesswork and dealership hassle out of the equation. Before we ship it, we program the module with the latest GM-certified software specifically for your vehicle using the VIN you provide. This ensures that when it arrives, it’s ready for installation, communicating perfectly with your car’s other systems, including the transmission, anti-theft, and emissions equipment. This isn’t just a part; it’s a complete, ready-to-install solution.
A Technician’s Notebook
I once had a 2008 Chevy Impala in the bay with a laundry list of complaints: harsh shifting, random stalling at idle, and a check engine light with codes for multiple unrelated sensors. The owner had already replaced the throttle body and a MAP sensor with no luck. The scan tool showed good data from the sensors, but the engine’s behavior was chaotic. This is a classic sign of an ECM with internal logic failure. After installing a VIN-programmed ECM like this one, every single issue vanished. The key was the VIN-specific programming; without it, the new module wouldn’t have recognized the car’s anti-theft system, and it would’ve been a no-start situation all over again. This simple step saves hours of diagnostic headaches and a tow to the dealer.
Is Your Cadillac Showing These ECM Failure Signs?
A faulty ECM can manifest in many ways. As a technician with over 20 years of experience, I’ve seen these symptoms countless times. If your vehicle is exhibiting any of the following, it’s time to inspect the ECM.
- ✔ Unexplained Check Engine Light with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- ✔ The engine cranks but refuses to start.
- ✔ Severe drop in fuel efficiency.
- ✔ Engine stalling or misfiring for no apparent reason.
- ✔ Harsh or unpredictable automatic transmission shifting.
- ✔ Apparent loss of power and poor acceleration.
- ✔ Communication errors with other modules on the vehicle network (U-codes).
Your Straightforward ECM Installation Guide
Installing your new 2006 DTS engine control module is a manageable task for a confident DIYer. Our pre-programming service handles the most complex part, making the physical swap much simpler. Always consult a repair manual for your specific vehicle’s torque specs and procedures.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent any accidental reconnection.
- Locate the ECM: On the 2006 Cadillac DTS, the ECM is typically found in the engine compartment. It’s a metal box with large electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical harnesses from the old module. There are usually locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount the new, programmed ECM onto the bracket and tighten the bolts securely. Reconnect the electrical harnesses, ensuring they click firmly into place.
- Reconnect the Battery: Re-attach the negative battery terminal.
- Security Relearn Procedure: In many GM vehicles, a simple security relearn procedure may be necessary. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This allows the anti-theft system to recognize the new ECM. After this, the vehicle should start and run correctly.
Verified Fitment Across a Wide Range of GM Vehicles

Your Vehicle Identification Number (VIN) allows us to program the ECM with the exact software and calibrations for your specific vehicle. This includes engine parameters, transmission type, and anti-theft system information, ensuring seamless communication and plug-and-play installation.
Is this a difficult part to install myself?
For most DIYers with basic tools, this is a very manageable job. Since we handle the programming, the physical swap is straightforward. See our installation guide above for the basic steps. The most critical part is disconnecting the battery first.
Will this fix my Check Engine Light?
If the Check Engine Light is caused by an internal ECM failure (like codes P0601-P0606), then yes, this part is the correct fix. However, the light can be on for hundreds of other reasons. Always perform a proper diagnosis or have a professional scan the codes before ordering.
What if I order the wrong part?
By providing your VIN at checkout, you eliminate the risk of ordering the wrong part. We use your VIN to verify that this module is 100% correct for your vehicle before we program and ship it.
Is any other programming required after installation?
No. Our service includes loading the latest GM software, so you will not need to take it to a dealership for additional programming. You may need to perform a simple security relearn procedure, which takes about 30 minutes and requires no special tools.
