We offer a dependable, direct-fit solution with this 2006 Uplander Powertrain Control Module, which arrives at your door programmed and ready for installation.
Forget the expensive dealership visit and the hassle of coordinating programming. We handle the critical software flashing for you. Simply provide your vehicle’s VIN during checkout, and our experienced technicians will load the latest, most stable GM software specific to your van. This ensures all engine and transmission parameters are set correctly, restoring the smooth operation and efficiency you expect. This is the most straightforward way to get your vehicle back on the road and running right.
From the Diagnostic Bay: The Case of the Intermittent No-Start
A customer brought in a 2006 Uplander that would intermittently refuse to start. It wouldn’t crank, and there were no obvious signs of a bad battery or starter. After running diagnostics, I noticed a U0100 ‘Lost Communication with ECM/PCM’ code that would appear randomly. In my 20+ years, I’ve seen this hundreds of times. The internal processors of the PCM were failing intermittently, especially with temperature changes. Instead of throwing parts at it, we confirmed the diagnosis by monitoring live data streams during the fault. Replacing the module with a properly programmed unit like this one solved the problem permanently. It’s a classic failure mode for this generation of electronics.
Common Signs of a Failing PCM
- ✔ Your vehicle fails to start or stalls unexpectedly.
- ✔ The check engine light is illuminated, often with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools.
- ✔ The engine runs rough, misfires, or lacks power.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes for the system capacitors to discharge.
- ✔ Locate the Module: On the 2006 Uplander, the PCM is typically found in the left-hand (driver’s side) front of the engine compartment.
- ✔ Disconnect Connectors: Carefully unclip and remove the electrical wiring harnesses connected to the old module. Inspect the connectors for any corrosion or damage.
- ✔ Remove the Old PCM: Unbolt the old module from its mounting bracket. Keep the mounting hardware as you will need it for the new unit.
- ✔ Install the New Module: Mount your new, pre-programmed PCM onto the bracket and secure it with the original hardware.
- ✔ Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click into place. Reconnect the negative battery terminal.
- ✔ Perform Security Relearn (If Necessary): In many cases, a security relearn procedure is required for the vehicle to recognize the new PCM and start. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. Consult your vehicle’s service information for the exact procedure.

Frequently Asked Questions
Frequently Asked Questions
How does the VIN programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest official GM software for your specific vehicle and flash it onto the module before shipping. This ensures it works correctly right out of the box.
Do I need any special tools to install this PCM?
No special tools are required. Basic hand tools like a socket set are all you need to physically swap the module. You will not need a high-end scan tool for programming, as we’ve already taken care of that for you.
Is a security relearn procedure always necessary?
On most GM vehicles of this era, a security relearn (also known as a Passlock or anti-theft relearn) is required. It’s a simple procedure you can do yourself with the ignition key and does not require any tools. It syncs the new PCM with your vehicle’s anti-theft system.
Will this fix my specific check engine light code?
This module is a direct solution for internal PCM failure codes like P0601, P0602, P0606, and communication codes like U0100. If your check engine light is caused by a faulty sensor or other component, this will not resolve that issue. Proper diagnosis is key.
