Restore Peak Performance and Reliability to Your Truck
Is your 2007 GMC Canyon, Chevrolet Colorado, or Hummer H3 suddenly running rough, stalling, or refusing to start? Are you battling a persistent Check Engine Light with codes that just won’t go away? Before you start throwing expensive sensors at the problem, consider the brain of your vehicle’s operation: the Powertrain Control Module (PCM). As a technician with over two decades of diagnostic experience, I’ve seen countless hours and dollars wasted on misdiagnoses when the root cause was a failing PCM. This module is the central command for your engine and transmission, and when it falters, the symptoms can be confusing and widespread.
This isn’t just a replacement part; it’s a complete solution. We are providing a genuine GM Powertrain Control Module, part number 19210067 (interchangeable with 12602010), that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that all factory settings, fuel maps, and transmission shift points are perfectly calibrated for your truck’s unique configuration. By flashing the module with the latest GM software updates before it even ships, we eliminate the need for a costly trip to the dealership for programming. This is the definitive fix for a faulty computer, designed to get you back on the road with confidence.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2007 Colorado that came into my shop with a bizarre set of symptoms. The owner had already replaced the throttle body and a couple of O2 sensors trying to fix an erratic idle and poor fuel mileage. The codes were all over the place. After checking the basics—fuel pressure, wiring harnesses, and sensor data—nothing seemed out of line. On a hunch, I monitored the PCM’s internal processor. It was dropping communication intermittently. We installed a VIN-programmed PCM, performed the security relearn, and the truck immediately ran like new. It’s a classic case where the ‘brain’ was the problem, not the ‘body’.
Common Signs of a Failing PCM
If your vehicle is experiencing any of the following, a faulty PCM could be the culprit. A failing module can often generate a variety of Diagnostic Trouble Codes (DTCs), including the critical P0601, P0606 (Internal Control Module Failure), or U-series communication codes.
- ✔ Engine stalling or misfiring for no apparent reason
- ✔ Complete no-start condition where the engine cranks but won’t fire
- ✔ Drastic decrease in fuel economy
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Check Engine Light is on with multiple, seemingly unrelated codes
- ✔ Failure to communicate with a diagnostic scan tool
A Straightforward Guide to Installation
Installing your new 2007 Canyon PCM is a job most DIYers can handle in their own driveway. The key is to follow the security relearn procedure after installation, which is essential for your vehicle to recognize the new module and start.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow all system capacitors to discharge.
- Locate the PCM: On the 2007 Canyon and Colorado, the PCM is typically located on the right-hand (passenger side) of the firewall in the engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors. There are usually locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket and remove it.
- Install the New Module: Bolt the new, pre-programmed PCM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Reconnect Battery: Reattach the negative battery terminal and tighten it.
- Perform Security Relearn (CRITICAL): You must complete the GM Security Relearn Procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. This allows the vehicle’s anti-theft system to sync with the new PCM. Your vehicle will not start until this is done.

Frequently Asked Questions about the 2007 Canyon PCM
Do I need to do any programming myself?
No. We handle all the programming before we ship the part. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready for installation and the security relearn procedure.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a placard on the driver’s side dashboard visible through the windshield.
Is the security relearn procedure difficult?
Not at all! It requires no special tools, just patience. The 3-cycle key-on/key-off process is straightforward and we recommend searching for a video of the ‘GM Passlock Relearn’ for a visual guide. Your truck will not start without it.
Will this fix my specific check engine light codes?
This PCM is a direct solution for internal module failure codes like P0601 or P0606. If you have other codes, this may resolve them if they were caused by the faulty PCM, but it’s important to ensure other components (like sensors or wiring) are not the root cause.
What if I have a different part number on my old module?
Part number 19210067 is the service replacement for several original numbers, including 12602010. As long as your vehicle is on the compatibility list, our VIN programming will ensure it functions correctly as the proper replacement.
