Restore Peak Performance to Your GM Vehicle
Is your 2006 Pontiac Torrent, Chevy Equinox, or Buick Rendezvous running rough, stalling, or displaying a persistent Check Engine Light? These are classic signs that the heart of your vehicle’s engine management system, the Powertrain Control Module (PCM), may be failing. This replacement PCM, part number 12600928, is the definitive solution to restore your vehicle’s reliability, efficiency, and drivability. It serves as the central command for your engine and transmission, and when it falters, the entire vehicle suffers. We take the guesswork out of the repair by programming this module specifically to your vehicle’s VIN, ensuring a seamless and effective installation.
From the Diagnostic Bay
We had a 2006 Chevy Uplander come in that had stumped two other shops. The owner complained of harsh, erratic shifting and occasional stalling at stoplights. The transmission had been serviced, solenoids were checked, but the problem persisted. All signs pointed to a costly transmission rebuild. However, after hooking up our advanced scanner, we noticed erratic data PIDs coming from the PCM. The module wasn’t correctly interpreting sensor data, causing it to send incorrect commands to the transmission. We installed a VIN-programmed PCM just like this one, performed the security relearn, and the van drove like it just rolled off the assembly line. It’s a powerful reminder that the PCM is the true brain of the operation, and its health is critical for both the engine and transmission.
Common Symptoms of a Failing 2006 Torrent Powertrain Control Module
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following issues, your engine computer is a likely culprit. This module is the correct fix for these common problems.
- ✔ Check Engine Light: The most common indicator, often with communication-related trouble codes (U-codes) or multiple, seemingly unrelated sensor codes.
- ✔ Engine Stalling or Misfiring: The PCM may fail to properly control ignition timing or fuel injection, leading to rough idling, stalling, or misfires.
- ✔ Poor Fuel Economy: Incorrect air/fuel mixture calculations can cause your vehicle to consume significantly more fuel than usual.
- ✔ Erratic Transmission Shifting: The PCM also controls transmission shift points. A faulty module can cause harsh shifting, delayed engagement, or getting stuck in one gear.
- ✔ No-Start Condition: In severe cases, the PCM can fail completely, preventing the vehicle from starting at all by cutting off fuel or spark.
- ✔ Failed Emissions Test: A malfunctioning PCM can prevent the engine from running cleanly, leading to an automatic failure at the emissions station.
VIN-Programmed for a Hassle-Free Installation
Unlike a generic module from a parts store or salvage yard, this unit is not just a piece of hardware. It’s a complete solution. Before we ship it, our technicians use your vehicle’s unique Vehicle Identification Number (VIN) to load the latest, most stable GM-approved software directly onto the module. This critical step ensures that the PCM recognizes all of your vehicle’s specific options, security systems, and operational parameters. This process eliminates the need for expensive trips to the dealership for programming, saving you time and money.

After installation, some vehicles may require a simple, key-on/key-off security relearn procedure, which you can typically perform yourself in your driveway. Instructions can be easily found online or in your vehicle’s service manual. In some cases, a Crankshaft Position Sensor (CASE) relearn may be needed, which requires a capable scan tool.
Frequently Asked Questions
Is this module ready to install right out of the box?
Yes! We program the module with the latest GM software using the VIN you provide during checkout. This makes it a plug-and-play installation for most vehicles. Some models may require a simple security relearn procedure that takes about 10-15 minutes to complete.
What happens if I install it without programming?
An unprogrammed module will not work. It will not be able to communicate with your vehicle’s other modules, security system, or sensors, resulting in a no-start condition and multiple error codes. Our VIN programming service is essential for proper function.
Where is the PCM located on my 2006 Pontiac Torrent?
On the 2006 Pontiac Torrent and Chevrolet Equinox, the Electronic Control Module is typically located in the left-hand (driver’s side) front of the engine compartment, often near the air filter housing.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive and validate your VIN, as it is required for the programming process.
Will this fix my check engine light?
This module is a direct solution for problems caused by a faulty PCM. If your check engine light is on due to internal module failure or communication errors originating from the PCM, this part will resolve the issue. However, it will not fix problems caused by other faulty components like sensors or wiring.
