Restore Peak Performance to Your Chevrolet Uplander
Is your 2006 Chevrolet Uplander running rough, stalling unexpectedly, or displaying a persistent check engine light? These are common indicators of a failing Engine Control Module (ECM), the central computer of your vehicle. A faulty ECM can cripple your van’s performance, fuel economy, and reliability. This direct-fit replacement Engine Control Module, part number 12602044, is the definitive solution to get your vehicle operating precisely as it did from the factory.
From the Diagnostic Bay
We had a 2006 Uplander come into the shop with a frustrating, intermittent no-start condition. The owner had already replaced the battery and starter with no luck. The scanner was throwing a dozen communication codes that didn’t seem related. Instead of just throwing parts at it, we checked the ECM power and ground circuits. We found a corroded ground wire near the module. After cleaning it, half the codes vanished, but the van still ran poorly. The intermittent power loss from the bad ground had damaged the internal processors of the original ECM. Installing a properly programmed replacement like this one was the final step that brought the vehicle back to perfect running condition. It’s a great reminder that while the ECM can be the root cause, always check the simple connections first!
Symptoms of a Failing 2006 Uplander ECM
If you’re experiencing any of the following issues, your engine computer may be the culprit. A failing ECM can manifest in various ways, often mimicking other component failures. Confirming the diagnosis is key, but these symptoms are strong indicators that your module needs attention.
- ✔ Check Engine Light: The most common sign. The light may be on constantly or flash intermittently.
- ✔ Engine Stalling or Misfiring: The engine may cut out while driving or idle erratically.
- ✔ No-Start Condition: The engine cranks but refuses to start, indicating a lack of fuel or spark control.
- ✔ Poor Fuel Economy: A sudden, unexplained drop in MPG can be caused by incorrect fuel mixture calculations from a faulty ECM.
- ✔ Failed Emissions Test: The ECM plays a crucial role in managing your vehicle’s emissions systems.
- ✔ Shifting Problems: In many vehicles, the ECM works with the transmission control module, and a failure can lead to harsh or erratic shifting.

Instructions are widely available online.
How can I be sure my old ECM is the problem?
While the symptoms listed are strong indicators, we always recommend a thorough diagnosis by a qualified mechanic. This includes checking for trouble codes, verifying power and ground signals to the ECM, and ruling out other potential issues like faulty sensors or wiring problems.
