Is Your Truck Plagued by Mysterious Electrical Problems?
If your 2007 GMC Canyon, Chevy Colorado, or other compatible GM vehicle is suddenly stalling, refusing to start, or throwing a confusing array of check engine light codes, the problem might be its electronic brain: the Powertrain Control Module (PCM). As a mechanic with over 20 years of diagnostic experience, I’ve seen firsthand how a failing PCM can turn a reliable truck into a source of constant frustration. Symptoms often start smallโa slight hesitation, an occasional hard startโbefore escalating into a no-start condition that leaves you stranded.
This isn’t just an inconvenience; it’s a critical failure. The PCM governs everything from fuel injection and ignition timing to transmission shifting and emissions control. When it falters, your vehicle’s performance, fuel economy, and reliability are compromised. Don’t let a faulty computer dictate your truck’s future.
The Direct-Fit, No-Hassle Solution: A Pre-Programmed PCM
This Powertrain Control Module, part number 19210067 (also interchangeable with 12602010), is the definitive solution to restore your vehicle’s proper function. We take the biggest headache out of the repair process: programming. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this module with the latest, most stable software updates directly from GM. It arrives at your door ready to install, saving you a costly trip to the dealership and their programming fees.
A Real-World Scenario from My Shop
“A customer brought in his ’07 Colorado that would intermittently crank but not start. He had already replaced the fuel pump and crank sensor based on advice he found online, with no luck. After connecting my scan tool, I found a U-series communication code, indicating a module wasn’t talking. We traced it to a faulty PCM. Instead of a complex and expensive dealer repair, we installed one of these pre-programmed modules. The truck fired up on the first try and has been running perfectly ever since. It’s often the central component that’s overlooked.”
Common Symptoms of a Failing 2007 Canyon PCM:
- โ Complete no-start or crank-no-start condition.
- โ Engine stalling or shutting off while driving.
- โ Harsh or erratic automatic transmission shifting.
- โ Significant drop in fuel efficiency for no apparent reason.
- โ Check Engine Light with communication codes (U-codes) or multiple random error codes.
- โ Inconsistent or non-functional electronic throttle control.
Plug-and-Play Installation: No Dealer Visit Required
Designed for both professional technicians and capable DIYers, installing this module is straightforward. On most of these trucks, the PCM is located on the right-hand (passenger side) firewall in the engine bay.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post.
- Locate the PCM: Find the module on the passenger-side firewall. It will have several large electrical connectors attached.
- Disconnect and Remove: Carefully release the locking tabs on each electrical connector and pull them straight out. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed PCM into place. Firmly reconnect the electrical harnesses, ensuring they click and lock securely.
- Final Step: Reconnect the negative battery terminal. The vehicle may need to idle for a few minutes as it completes its internal relearn processes.

Frequently Asked Questions (FAQ)
- Q: How do I know for sure that my PCM is the problem?
- A: While the symptoms above are strong indicators, the best way is with a professional diagnosis. Key signs are communication-related trouble codes (like U0100), or if a scan tool cannot communicate with the engine computer at all.
- Q: What does ‘VIN Programmed’ mean?
- A: It means we load your vehicle’s specific Vehicle Identification Number (VIN) and the corresponding factory software onto the module before shipping. This ensures it communicates correctly with your truck’s other systems, like the anti-theft and transmission controls.
- Q: Will I need to do anything else after installation?
- A: In most cases, no additional procedures are needed. The module is sent ready for installation. On rare occasions, a specific vehicle may require a security or crankshaft position sensor relearn, which can be performed with many professional-grade scan tools.
- Q: Where do I provide my VIN?
- A: After you complete your purchase, you will need to send us your 17-digit VIN. We cannot process and ship your order until we receive this information to ensure correct programming.
- Q: Is this part number 19210067 the same as 12602010?
- A: Yes, these part numbers are often used interchangeably for this specific family of GM electronic control modules. This unit is a correct replacement for either number listed on your original part.
