Is Your Truck Plagued by Mysterious Electrical Gremlins?
If your 2007 Chevrolet Colorado, GMC Canyon, or Hummer H3 is suddenly stalling, refusing to start, shifting erratically, or throwing a cascade of confusing check engine light codes, a failing Powertrain Control Module (PCM) is the most likely culprit. As the central computer of your vehicle, a faulty PCM can cause immense frustration and leave you stranded. Stop the endless cycle of guesswork and parts-swapping. This is the definitive, reliable solution to restore your vehicle’s performance and dependability.

This PCM, part number 12602010 / 19210067, arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We load the latest, most stable software updates from GM, ensuring your engine and transmission operate exactly as the manufacturer intended. This is a true plug-and-play fix designed for both professional technicians and determined DIYers.
A Real-World Scenario from My Shop
A customer’s 2007 Colorado came in last month with a no-start condition after randomly stalling at a stoplight. The local parts store sold him a new crankshaft sensor and camshaft sensor, but the problem persisted. His scanner showed a U0100 ‘Lost Communication with ECM/PCM’ code. After verifying the PCM had good power and ground, we knew the module itself had failed internally. We installed one of our VIN-programmed units, performed the quick security relearn, and the truck fired right up and has been running perfectly ever since. This simple swap saved him from what could have been a thousand-dollar dealership bill.
Symptoms of a Failing 2007 Colorado PCM
If you’re experiencing any of the following issues, a faulty engine computer is a strong possibility:
- โ Vehicle will not start, or starts and immediately stalls.
- โ Check Engine Light is on with communication error codes (like U-codes).
- โ Poor fuel economy and engine performance.
- โ Harsh or erratic automatic transmission shifting.
- โ The engine runs rough, misfires, or hesitates on acceleration.
- โ Apparent failure of multiple sensors at once.
Plug-and-Play Installation: No Dealer Visit Required
Installing your new PCM is straightforward. On the 2007 Colorado and Canyon, the module is located on the right-hand (passenger side) firewall in the engine bay.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting work.
- Locate the PCM: Find the module on the passenger-side firewall. It’s a silver metal box with several large electrical connectors.
- Disconnect Connectors: Carefully unlatch and remove all electrical harness connectors from the old PCM. Inspect them for any corrosion or damage.
- Swap the Module: Unbolt and remove the old PCM. Mount the new module securely in its place.
- Reconnect Everything: Firmly plug all the harness connectors into your new PCM. Reconnect the negative battery terminal.
- Perform Security Relearn: You will need to perform a simple security relearn procedure so the vehicle recognizes the new module. This typically involves turning the key to the ‘ON’ position for 10-12 minutes. See our FAQ below for more details.

Frequently Asked Questions (FAQ)
Q: How do I know for sure that my PCM is the problem?
A: While the symptoms listed above are strong indicators, the best way is through a proper diagnosis. Key signs include communication-related trouble codes (U-codes), multiple unrelated sensor codes appearing at once, and ruling out wiring or power/ground issues to the module.
Q: Is this part really ready to install when it arrives?
A: Yes! You provide us with your VIN during checkout, and we program the module with the correct, updated GM software for your specific vehicle. It is ready for installation and the security relearn procedure right out of the box.
Q: Where is the PCM located on my 2007 Colorado?
A: On the 2007 Chevrolet Colorado, GMC Canyon, and Hummer H3, the PCM is mounted to the firewall on the passenger side of the engine compartment.
Q: What is the ‘security relearn’ and is it difficult?
A: It’s a simple anti-theft sync procedure that is very easy. After installation, you’ll typically turn the key to the ‘ON’ position (without starting the engine) for 10 minutes, then OFF for 10 seconds, and repeat this two more times. On the third cycle, the vehicle should start and run normally.
Q: Do I need any special tools for this job?
A: No special programming tools are required. You will only need basic hand tools, such as a socket set, to disconnect the battery and unbolt the module from the firewall.
