Restore Peak Performance to Your Chevrolet Uplander
Is your 2006 Chevrolet Uplander running rough, stalling unexpectedly, or showing a persistent Check Engine Light? These are classic signs of a failing Engine Control Module (ECM), the computer that serves as your vehicle’s brain. A faulty ECM can cause a cascade of frustrating issues, from poor fuel economy to erratic transmission shifting. This isn’t just an inconvenience; it can affect your vehicle’s reliability and safety. This replacement ECM is the dependable, straightforward solution to get your van running like new again.
We take the guesswork and high cost out of the repair. Unlike a generic module from a parts store, this unit comes fully programmed to your specific vehicle using your VIN. We install the latest GM factory software, ensuring all systems communicate perfectly from the moment you install it. This means no expensive trips to the dealership for programming—a savings of both time and money. This is the same quality and precision you’d get from a professional shop, delivered right to your door.
A Technician’s Notebook: The Intermittent Gremlin
A customer brought in their 2006 Uplander with a problem that was driving them crazy: it would randomly lose power and sometimes stall at red lights, but with no consistent trouble codes. We checked the fuel pressure, spark, and sensors—all were fine. After hours on the diagnostic scanner, we noticed the live data stream from the ECM would occasionally freeze just before a stall. This is a tell-tale sign of an internal ECM failure. The internal processors were breaking down under heat and load. We replaced it with a VIN-programmed module like this one, and the problem was solved instantly. These intermittent issues are often the hardest to pin down and almost always lead back to the ECM.
Is Your Uplander Showing These Symptoms?
A failing ECM can manifest in many ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Diagnostic Trouble Codes (DTCs) related to internal module failure (e.g., P0601, P0606) or communication errors (U0100).
- ✔ Engine cranks but refuses to start.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Apparent loss of power despite a healthy engine.
A Straightforward Guide to Installation
Installing your new 2006 Uplander Engine Control Module is a job most DIYers can handle with basic tools. Our pre-programming makes it a true plug-and-play repair.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental reconnection.
- Locate the ECM: On the 2006 Uplander, the Engine Control Module is typically found in the left-hand (driver’s side) of the engine compartment. It’s a metal box with large electrical connectors.
- Disconnect the Old Module: Carefully release the locking tabs on the electrical harness connectors and pull them straight out. Avoid wiggling them side-to-side. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new ECM into place. Firmly press the electrical connectors into their sockets until you hear and feel them click, then secure the locking tabs.
- Final Steps: Reconnect the negative battery terminal. Your vehicle may require a security relearn procedure, which typically involves cycling the key in the ignition. Consult your owner’s manual or a reliable online resource for the specific steps for your vehicle.

Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives at your door fully programmed with the latest GM software, matched specifically to the VIN you provide at checkout. It is ready for installation right out of the box.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your vehicle. You can find it on your vehicle’s registration, insurance card, or on a small plate on the driver’s side dashboard, visible through the windshield.
Is this a difficult part to install for a DIYer?
For most individuals with basic mechanical skills, this is a very manageable job. It involves disconnecting the battery, unplugging the old module, unbolting it, and then reversing the process with the new one. No special tools are typically required.
Will this fix my Check Engine Light?
If the Check Engine Light is caused by a faulty ECM (confirmed by diagnostic codes like P0601 or other symptoms), then yes, this part is designed to resolve that issue. It is always recommended to diagnose the root cause of the light before ordering parts.
What if I have a different part number on my old ECM?
Please check the list of interchangeable service numbers (12602044, 12603530, etc.) in the description. If your number matches one of those, this part will work. If not, please contact us to ensure you get the correct module for your vehicle.
