Restore Your Uplander’s Performance and Reliability
As a technician with over two decades of experience under the hood, I’ve seen firsthand how a failing Engine Control Module (ECM) can turn a reliable vehicle into a source of constant frustration. If your 2006 Chevrolet Uplander is experiencing baffling issues like random stalling, a persistent Check Engine Light, poor fuel economy, or a no-start condition, the ECM is often the culprit.

From the Diagnostic Bay: The Intermittent No-Start Nightmare
I remember a 2006 Uplander that came into my shop with an issue that was driving the owner crazy. It would start perfectly for a week, then refuse to crank for two days, with no rhyme or reason. The battery was new, the starter checked out, and there were no consistent trouble codes. After hours of tracing wires and checking grounds, we hooked up a scope to the ECM’s power and communication lines. We found that the ECM’s internal voltage regulator was failing intermittently, especially on hot days, causing it to shut down and prevent the start sequence. Swapping in a properly programmed ECM like this one solved the problem instantly. It’s a classic example of how a failing module can create ghost-in-the-machine problems that defy simple diagnosis.
Is Your Vehicle Showing These Symptoms?
A faulty ECM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your engine’s computer needs attention:
- ✔ Check Engine Light is on with codes like P0601, P0605, or U0100.
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained drops in fuel efficiency.
- ✔ The vehicle stalls unexpectedly while driving or at idle.
- ✔ Rough idling, misfires, or hesitation during acceleration.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Communication errors with your diagnostic scan tool.
A Straightforward Guide to Installation
Installing your new 2006 Uplander Engine Module is a manageable job for a DIYer with basic tools. Following these steps ensures a smooth process.
- 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 silver metal box with several large electrical connectors.
- Disconnect the Connectors: Carefully release the locking tabs on each wiring harness connector and pull them straight out from the module. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware, as you may need it for the new module.
- Install the New Module: Mount the new, pre-programmed ECM onto the bracket and secure it with the original bolts.
- Reconnect Everything: Firmly plug the wiring harness connectors back into the new module until they click into place. Reconnect the negative battery terminal. The vehicle is now ready to start.

Frequently Asked Questions
How does the VIN programming work?
After you complete your purchase, simply reply to your order confirmation email with your vehicle’s 17-digit VIN. Our technicians will use this to load the correct, factory-updated software onto the module before shipping, ensuring it’s a perfect match for your vehicle’s specific configuration.
Do I need to have any other procedures done after installation?
In most cases, no additional procedures are needed. Because the module is pre-programmed, it is ready for immediate use. On some vehicles, a security relearn or crankshaft position sensor relearn may be necessary, which can often be done without a scan tool. Instructions can be provided upon request.
Is this part difficult to install myself?
For most DIYers with basic mechanical skills, this is a very straightforward installation. It typically involves disconnecting the battery, unplugging a few connectors, and removing a few bolts. No special tools are required for the physical swap.
Will this fix my ‘Check Engine’ light?
If the Check Engine Light is caused by an internal failure of the ECM (common codes include P0601-P0606), then yes, this part is the correct fix. It’s always best to have the codes read with a scanner to confirm the diagnosis before ordering.
What if my original part number is different?
This module is a direct replacement for several service numbers, including 12590032, 12602044, 12603530, and more. As long as your original part number is on our interchange list, this module will work perfectly once programmed to your VIN.
