Restore the Flawless Performance of Your Cadillac
Is your Cadillac DTS experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? These problems can disrupt the smooth, luxurious ride you expect and create unnecessary stress. A failing Engine Control Module (ECM) is often the culprit, acting as the brain of your vehicle and controlling everything from fuel mixture to ignition timing. This isn’t just an inconvenience; it’s a critical failure that compromises your car’s reliability and performance. Don’t let a faulty computer keep your DTS off the road. We have the precise, reliable solution you need.

Frequently Asked Questions
Do I need to do any special programming myself?
No. We program the module to your vehicle’s VIN before it ships. In most cases, it is a direct installation. However, some vehicles may require a simple security relearn procedure (often involving turning the key on for 10-15 minutes) or a Crankshaft Variation Relearn (CASE), which can be performed with a capable scan tool. These are standard GM procedures and are not considered programming.
How do I provide my vehicle’s VIN?
You can provide your 17-digit Vehicle Identification Number (VIN) during the checkout process. This is crucial for us to program the 2009-2011 Cadillac DTS engine control module correctly for your specific vehicle.
How can I be sure this part will fit my car?
This ECM is the correct fit for the 2009-2011 Cadillac DTS. It also fits a wide range of other GM vehicles, as listed in the fitment guide. Providing your VIN ensures we program it for your exact make and model, guaranteeing compatibility.
What are the most common signs of a bad ECM?
The most common symptoms include a check engine light that won’t turn off, engine stalling or misfiring, poor fuel economy, transmission shifting problems, and a complete failure to start. You may also have specific diagnostic codes stored in the system, such as P0601 (Internal Control Module Memory Check Sum Error).
Is this a difficult part to install?
For someone with moderate mechanical experience, the physical installation is straightforward. The ECM is typically located in the engine bay and is secured with a few bolts and electrical connectors. Always disconnect the battery before beginning the installation. If you are not comfortable performing the work, we recommend consulting a qualified mechanic.
