Is Your Cadillac DTS Running Rough? The Solution is Here.
If you’re experiencing frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a no-start condition, a failing Engine Control Module (ECM) is often the culprit. The ECM is the brain of your vehicle’s engine, controlling everything from fuel mixture and ignition timing to transmission shifting. When it fails, the entire system suffers. This direct-fit Engine Control Module, part number 19210737, is the definitive solution to restore your 2006 Cadillac DTS to its original factory performance.
From the Diagnostic Bay
We had a 2006 DTS come into the shop with a laundry list of seemingly unrelated problems: intermittent stalling at red lights, hard shifting, and a check engine light with codes for multiple different sensors. The owner had already spent a small fortune replacing the throttle body and a couple of O2 sensors with no improvement. After running a full diagnostic, we traced the electrical noise and erratic sensor readings back to a single point of failure: the ECM. The internal processors were failing, sending corrupt data throughout the car. Installing a VIN-programmed 2006 DTS Engine Module like this one solved every single issue at once. It’s a powerful reminder that sometimes the ‘brain’ is the problem, not the ‘senses’.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light is on or flashing
- ✔ Engine stalling or misfiring unexpectedly
- ✔ Noticeable decrease in fuel efficiency
- ✔ Vehicle has trouble starting or won’t start at all
- ✔ Rough idling or poor acceleration
- ✔ Automatic transmission shifting erratically or harshly
- ✔ Communication errors with diagnostic scan tools

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This is the primary benefit of our service. We program the module to your vehicle’s specific VIN before we ship it. This means it arrives ready for installation, saving you a trip to the dealership and avoiding their expensive programming fees.
How do I find my vehicle’s VIN?
Your VIN is a unique 17-digit number. You can typically find it on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a difficult part to install?
For the 2006 Cadillac DTS, the ECM is located in the engine compartment. Installation is generally straightforward for someone with moderate mechanical skill. It involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and then reversing the process. However, we always recommend consulting a service manual or having a professional mechanic perform the installation if you are unsure.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue and allow the light to be cleared. It is crucial to ensure the ECM is the true source of the problem. We recommend a proper diagnosis before ordering to confirm the failure.
What is the difference between an ECM and a PCM?
ECM stands for Engine Control Module, while PCM stands for Powertrain Control Module. In many modern vehicles, these terms are used interchangeably. A PCM controls both the engine and the transmission, while a dedicated ECM may only control engine functions. This particular part serves as the primary engine computer for the vehicles listed.
