Is Your Truck Running Rough? It Might Be Time for a New Engine Computer
If your 2007 Isuzu I-370, or a similar GM truck like the Colorado, Canyon, or Hummer H3, is experiencing frustrating issues like stalling, a persistent check engine light, or a no-start condition, the root cause is often a failing Powertrain Control Module (PCM). The PCM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting. When it starts to fail, it can create a cascade of problems that are often misdiagnosed, leading to wasted time and money on unnecessary sensor replacements.
This replacement PCM, part number 19210067 (interchangeable with 12602010), is the definitive solution to restore your vehicle’s performance and reliability. Unlike a generic part from a local store or a junkyard module that won’t work, this unit is professionally programmed specifically for your truck. We use your vehicle’s unique Vehicle Identification Number (VIN) to load the latest GM-certified software and calibrations. This ensures seamless communication with all other modules in your vehicle and restores the precise operational parameters your engine was designed for.
From the Diagnostic Bay
We once had a 2007 GMC Envoy come in that had its owner completely stumped. The truck would randomly stall at red lights and had a laundry list of seemingly unrelated trouble codes—O2 sensor faults, random misfires, and a transmission communication error. The owner had already replaced three sensors and the spark plugs with no improvement. After hooking up our diagnostic tools, we noticed the live data stream from the PCM was freezing and dropping out intermittently. This pointed directly to an internal failure of the computer itself. We installed a VIN-programmed PCM just like this one, performed the security relearn, and the Envoy ran perfectly. All the phantom codes vanished, and the stalling issue was completely resolved. It’s a classic case of treating the disease, not just the symptoms.
Diagnosing a Faulty 2007 Isuzu I-370 PCM
A failing engine computer can manifest in numerous ways, making diagnosis tricky. If your truck is exhibiting several of the following symptoms, there is a high probability that the PCM is the culprit. This unit is the correct, pre-programmed solution to get you back on the road.
Common Failure Symptoms
- ✔ Check Engine Light: The light is on with codes related to internal module memory, processor failure (like P0601, P0606), or communication errors (U-codes).
- ✔ No-Start or Hard Starting: The engine cranks but refuses to start, or takes an excessively long time to fire up, especially when warm.
- ✔ Poor Engine Performance: You may notice a significant loss of power, hesitation during acceleration, or rough idling.
- ✔ Reduced Fuel Economy: A failing PCM can’t efficiently manage the engine’s fuel delivery, leading to a noticeable drop in MPG.
- ✔ Erratic Transmission Shifting: The PCM works with the transmission controller. Harsh shifts, delayed engagement, or getting stuck in a gear can be signs of a faulty computer.
- ✔ Intermittent Stalling: The vehicle may stall for no apparent reason while driving or when coming to a stop.

The process is simple: place your order, provide us with your VIN, and we handle the complex programming. The module you receive will be ready for installation, saving you a costly trip to the dealership. After installation, a simple security relearn procedure may be required, which you can typically do yourself in about 30 minutes without any special tools.
Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. This service is included in the purchase price. It arrives ready for installation, saving you time and the high cost of dealership programming.
Where is the PCM located on my 2007 Isuzu I-370?
On the 2007 Isuzu I-370, Chevrolet Colorado, and GMC Canyon, the Electronic Control Module is typically located on the right-hand (passenger) side of the firewall in the engine bay.
What is the security relearn procedure?
After installing the new PCM, you may need to perform a security relearn to sync the module with your vehicle’s anti-theft system. This procedure usually involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. Specific instructions for your vehicle are widely available online.
Will this fix my specific check engine light codes?
This PCM will resolve issues caused by a faulty computer, including internal processor and memory error codes (e.g., P0601-P0606). However, if your codes are for specific sensors (like an oxygen sensor or MAP sensor), you should diagnose those components first. A failing PCM can sometimes cause false sensor codes, but it’s not guaranteed to be the root cause.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive an email with instructions on how to reply with your vehicle’s 17-digit VIN. You can also add your VIN as a note during the checkout process. We cannot program and ship the module without it.
