Restore Your Vehicle’s Brainpower and Performance
Is your 2007 Isuzu I-370, GMC Canyon, Chevy Colorado, or another compatible GM truck suffering from baffling engine issues? A faulty Powertrain Control Module (PCM), often called the engine computer, is frequently the hidden cause of poor performance, stalling, and persistent check engine lights. This direct replacement PCM, part number 12602010 (interchangeable with 19210067), is the definitive solution to get your vehicle running reliably again. It arrives pre-programmed with the latest GM software updates, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN). This eliminates the need for expensive dealership programming, saving you both time and money.
From the Diagnostic Bay
We had a 2007 Hummer H3 come into the shop with an intermittent no-start condition that was driving the owner crazy. He had already replaced the battery and the crankshaft position sensor based on forum advice, but the problem persisted. After connecting our diagnostic scanner, we found multiple communication error codes pointing towards the central computer. A quick voltage and ground check at the PCM connector confirmed our suspicions: the module itself was failing internally. We installed a VIN-programmed PCM just like this one, performed the security relearn procedure, and the H3 fired up instantly. It’s a classic case where chasing individual sensors can be a costly distraction from the root problem—the PCM.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Rough or erratic idling.
- ✔ A noticeable decrease in fuel economy.
- ✔ Failure to pass emissions testing.
- ✔ No-start or hard-starting conditions, especially when warm.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Communication errors with diagnostic scan tools.
Solving the Problem with a VIN-Programmed 2007 Isuzu I-370 PCM
The PCM is the central command center for your vehicle’s engine and transmission. It processes data from dozens of sensors to control fuel injection, ignition timing, emissions systems, and transmission shift points. When it fails, the entire powertrain can become unreliable. Our process ensures you receive a fully functional module that is ready for installation. By providing your VIN at checkout, we load the correct factory software and calibrations for your specific make, model, and options. This ensures seamless integration and restores the original performance and efficiency of your vehicle.
Simple Installation Process
While professional installation is always recommended, replacing the PCM is a straightforward process for a knowledgeable DIYer. The module is typically located on the right-hand (passenger side) firewall in the engine bay.
- Disconnect the Battery: Always disconnect the negative battery terminal before working on any electronic components.
- Locate and Remove the Old PCM: Carefully unplug the electrical connectors and unbolt the module from its mounting bracket.
- Install the New PCM: Mount the new module and securely reconnect all electrical harnesses.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Security Relearn (if necessary): Many GM vehicles require a security or anti-theft relearn procedure, which can often be done without special tools. This typically involves cycling the key in the ignition. Instructions are widely available online for your specific model.

Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your VIN (Vehicle Identification Number) allows us to program the PCM with the exact software and calibrations specific to your vehicle’s engine, transmission, and factory options. This ensures perfect compatibility and performance without needing a trip to the dealership.
Is this module difficult to install?
The physical installation is relatively simple, involving unplugging connectors and removing a few bolts. However, many GM vehicles require a security relearn procedure after installation. This procedure is straightforward and can typically be done in your driveway by cycling the ignition key. We recommend searching for the specific procedure for your model year.
Where is the PCM located on my 2007 Isuzu I-370?
For the Isuzu I-370, Chevrolet Colorado, GMC Canyon, and Hummer H3, the PCM is located in the engine compartment, mounted to the right-hand (passenger side) firewall.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM or an issue the PCM controls, then yes, this replacement part should resolve the problem. It is crucial to have your vehicle properly diagnosed to ensure the PCM is the source of the issue before ordering.
My original part number is 19210067. Will this work?
Yes. Part numbers 12602010 and 19210067 are interchangeable service numbers for this application. This module is a correct replacement for either original part number.
