Is your 2006-2007 Buick Rendezvous, or another compatible GM vehicle, suffering from perplexing issues like a persistent check engine light, poor fuel economy, erratic shifting, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM is responsible for managing the engine, transmission, and dozens of other critical systems. When it fails, it can cause a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs.
This is a direct replacement PCM, part number 19210070 (also compatible with service number 12600928), meticulously prepared for your specific vehicle. We eliminate the guesswork and the need for expensive dealership programming. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) during checkout, and our technicians will flash the module with the latest, most stable GM-certified software for your exact make and model. This ensures optimal performance, fuel efficiency, and emissions compliance right out of the box.
Diagnosing a Faulty Powertrain Control Module
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’ve replaced sensors and other parts without success, it’s time to consider the vehicle’s brain. This replacement 2006-2007 Rendezvous PCM is the definitive solution for restoring your vehicle’s operational integrity.
From the Diagnostic Bay
We had a 2006 Buick Terraza come into the shop with an intermittent stalling problem that was driving the owner crazy. It would die at stoplights, but then start right back up. No consistent codes were being stored, just a few random communication errors. We checked fuel pressure, the ignition system, and common sensors—all were fine. After connecting our high-level scan tool and monitoring live data, we noticed the PCM would momentarily stop communicating with the transmission module right before a stall. We swapped in one of our pre-programmed PCMs, performed the security relearn, and the problem was gone for good. It’s a classic case where the internal logic of the module begins to break down, causing ghost-like issues that are impossible to trace to a specific sensor.
Common Symptoms of PCM Failure
- ✔ Check Engine Light: The light is on, and you may have codes related to module communication (U-codes) or multiple, unrelated sensor codes.
- ✔ Engine Performance Issues: Stalling, rough idling, hesitation during acceleration, or a noticeable loss of power.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG is a strong indicator of a PCM issue.
- ✔ Transmission Problems: Harsh or delayed shifting, or the transmission getting stuck in one gear (limp mode).
- ✔ No-Start Condition: The engine cranks but refuses to start, often due to the PCM not firing the fuel injectors or ignition coils.
- ✔ Failed Emissions Test: The PCM is critical for managing your vehicle’s emissions systems.
The Importance of VIN Programming
You cannot simply install a used PCM from another vehicle. Each module is programmed with a specific VIN and the associated options for that car, such as engine size, transmission type, and emissions standards. Our professional programming service ensures this 2006-2007 Rendezvous PCM is a true plug-and-play solution. We load the latest GM updates, which often resolve factory bugs and improve overall vehicle performance and longevity. This is a critical step that dealerships charge hundreds of dollars for, but we include it with your purchase.
Simple Installation Process
Once you receive your pre-programmed module, installation is straightforward. The PCM is typically located in the engine bay on the driver’s side, inside the air filter box assembly. Disconnect the battery, unplug the electrical connectors from the old module, remove it, and install the new one. After reconnecting the battery, you will likely need to perform a simple security relearn procedure (often called a Passlock or Passkey relearn), which can be done without any special tools. Instructions for this procedure are widely available and typically involve turning the key to the ‘ON’ position for 10-15 minutes.

Frequently Asked Questions
Why do you need my VIN?
Your VIN (Vehicle Identification Number) is essential for us to program the PCM with the exact software and calibrations for your specific vehicle. This includes engine type, transmission, emissions systems, and other options, ensuring a perfect match and proper function.
Is this part difficult to install?
Installation is generally simple for someone with basic mechanical skills. It involves disconnecting the battery, swapping the module, and then performing a security relearn procedure. No specialized tools are typically required for the relearn.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this part will resolve the issue. However, it’s crucial to ensure the underlying problem isn’t a separate failed sensor or wiring issue. This module corrects problems originating from the computer itself.
What is a security relearn procedure?
It’s a simple process that syncs the new PCM with your vehicle’s anti-theft system. It usually involves leaving the key in the ‘ON’ position for about 10-15 minutes. This allows the new computer to recognize your existing keys.
Is there a core charge for my old part?
This listing does not require a core charge. You can keep your old module or recycle it locally without the hassle of shipping it back to us.
