Restore Peak Performance to Your Isuzu I-370
Is your 2008 Isuzu I-370 suffering from perplexing issues like a persistent check engine light, rough idling, unexpected stalling, or a sudden drop in fuel economy? These are classic symptoms of a failing Engine Control Module (ECM), the central computer that governs your truck’s engine performance. A faulty ECM can disrupt everything from fuel delivery and ignition timing to transmission shifting, making your vehicle unreliable and frustrating to drive. This replacement Engine Control Module, part number 12630457, is the definitive solution to restore your vehicle’s original performance and reliability.
From the Diagnostic Bay
We had a 2008 GMC Canyon (which uses the same platform as the I-370) come into the shop with a ghost of a problem. The owner complained of random stalling at stoplights and an occasional hard start. We checked the fuel pump, sensors, and wiring, but everything seemed fine. No consistent codes were being stored. Finally, after monitoring live data, we noticed the ECM was intermittently dropping communication. We swapped in a VIN-programmed module like this one, and the truck ran perfectly. It’s a reminder that when all the components check out, the conductor of the orchestra—the ECM—is often the culprit.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light: The most common indicator, often with codes related to sensors or internal processor faults.
- ✔ Engine Stalling or Misfiring: Inconsistent signals from the ECM can cause the engine to run poorly or shut off unexpectedly.
- ✔ Poor Fuel Economy: Incorrect fuel mixture and timing calculations lead to inefficient engine operation.
- ✔ No-Start Condition: The ECM may fail to activate the fuel pump or ignition system, preventing the engine from starting.
- ✔ Erratic Transmission Shifting: The ECM communicates with the transmission controller, and a fault can cause harsh or incorrect shifts.
- ✔ Performance Issues: Noticeable loss of power, hesitation during acceleration, or a rough idle.

What information do you need from me?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your 2008 Isuzu I-370. This is typically found on your driver’s side dashboard (visible through the windshield) or on the driver’s door jamb sticker.
Where is the ECM located on my 2008 Isuzu I-370?
On the 2008 Isuzu I-370, the ECM is typically located on the right-hand (passenger) side of the firewall in the engine bay. Always disconnect the battery before attempting to remove or install any electronic components.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to have your vehicle properly diagnosed to ensure the ECM is the root cause of the problem and not a faulty sensor or wiring issue.
Is any additional setup required after installation?
In some cases, a security relearn or crank variation relearn procedure may be necessary. These procedures are simple and can often be performed without special tools. Instructions are widely available, or your local mechanic can perform them quickly.
