Restore Peak Performance to Your Truck’s Engine
Are you battling frustrating issues like a persistent check engine light, poor fuel mileage, or an engine that just won’t run right? A failing Powertrain Control Module (PCM) is often the hidden culprit behind these headaches. As the central computer for your engine and transmission, its health is non-negotiable. This replacement PCM, part number 19210067, is the definitive solution for your 2007 Isuzu I-370 and a wide range of other GM trucks and SUVs. It arrives at your door fully programmed with the latest factory software, specifically matched to your vehicle’s VIN. This eliminates the need for an expensive trip to the dealership for programming.
Case Study: A Tricky Diagnosis
I once had a 2007 Chevy Colorado in my bay with an intermittent no-start condition and a stubborn P0606 (PCM Processor Fault) code. The owner had already replaced the crank sensor and a few other parts with no luck. The symptoms were erratic—sometimes it would start fine for a week, then fail three times in one day. After verifying the wiring and power/ground circuits to the module, we confirmed the internal processor was failing. A failing PCM can send you chasing ghosts. We installed a VIN-programmed module just like this one, performed the security relearn, and the truck has run flawlessly ever since. It’s a reminder that getting to the ‘brain’ of the problem is key.
Is Your Vehicle Showing These Symptoms?
A faulty PCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs attention:
- ✔ Persistent Check Engine Light (CEL)
- ✔ Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601, P0602, or P0606
- ✔ Communication loss codes like U0100
- ✔ Unexplained drop in fuel economy
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Complete no-start condition where the engine cranks but won’t fire
The Advantage of a Pre-Programmed 2007 Isuzu I-370 PCM
The biggest hurdle in replacing a modern engine computer is the programming. This module removes that obstacle. We handle the complex part for you. By flashing the unit with your vehicle’s VIN, we ensure it has the correct calibration files and the most recent GM software updates. These updates often correct underlying drivability issues and bugs that were present in the original software, leading to a smoother, more reliable driving experience. This is a direct, effective fix that restores your vehicle’s factory logic and performance.
A Straightforward Guide to Installation
Installing your new PCM is a manageable job for a DIYer with basic tools. Follow these steps carefully to ensure a smooth process.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental contact.
- Locate the PCM: On the Isuzu I-370, Chevy Colorado, and GMC Canyon, the PCM is typically located on the right-hand (passenger side) of the firewall in the engine bay. On Trailblazer/Envoy platforms, it’s on the left-hand (driver side) of the engine.
- Disconnect Connectors: Carefully release the locking tabs and disconnect all wiring harness connectors from the old module. Inspect the connectors for any corrosion or damage.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed PCM onto the bracket and securely fasten the bolts.
- Reconnect Everything: Plug the wiring harnesses back into the new module, ensuring they click securely into place. Reconnect the negative battery terminal.
- Perform Security Relearn: You will need to perform a simple vehicle anti-theft system (VATS) relearn. This procedure typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. This allows the new PCM to sync with your vehicle’s security system.

Frequently Asked Questions
What happens after I purchase?
After you place your order, you must send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it. This ensures you receive a part that is 100% correct for your specific vehicle configuration.
Is this a simple plug-and-play installation?
Yes, for the most part. The module is programmed to your VIN, so it’s ready to be installed. However, you will need to perform a standard GM security relearn procedure after installation, which takes about 30 minutes and does not require special tools.
Do I need to send my old PCM (core) back?
No core charge or return is required for this part. You can keep or recycle your old module.
Will this fix my specific problem?
This PCM will correct issues directly caused by a failing module, such as internal processor faults (P0606) or memory errors (P0601). While it is a very common failure point, we always recommend a proper diagnosis by a qualified technician to confirm the PCM is the root cause of your vehicle’s symptoms.
What if I have a different part number on my original module?
This module, part number 19210067, supersedes and is interchangeable with part number 12602010. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
