Common Symptoms & Your Solution
A faulty engine computer can manifest in numerous ways, disrupting your vehicle’s complex systems. If you’re experiencing any of the following, this module is the reliable fix you need:
- Check Engine Light (CEL): Particularly for communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or U-series codes.
- Poor Drivability: Unexplained stalling, hesitation during acceleration, or a significant drop in fuel economy.
- Transmission Problems: Harsh or incorrect gear shifting, as the PCM is critical for transmission control.
- No-Start Condition: The engine cranks but won’t start, often due to a lack of fuel injector or ignition coil signals from the PCM.
- Failed Emissions Test: Inability to pass smog or emissions testing due to internal module faults.
Our process eliminates the need for expensive dealership visits and programming fees. By providing us with your VIN upon purchase, you receive a unit that is ready for installation, designed to restore your Hummer’s original performance and reliability.

Expert Insight: Why VIN Programming is Non-Negotiable
In a vehicle like the Hummer H3, the engine computer is more than just an engine controller; it’s the central hub for the entire vehicle network. It communicates with the transmission, anti-lock brakes, body control module, and crucially, the anti-theft system (Passlock/VATS). Without precise VIN programming, these systems cannot recognize each other, leading to a no-start condition or a cascade of error codes. We handle this critical step for you, ensuring that when you install your new 2006 Hummer H3 Engine Control Module, it integrates seamlessly, just like the original factory part.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your 2006 Hummer H3. This is typically found on your driver’s side dashboard (visible through the windshield) or on your vehicle’s registration and insurance documents.
Is this part difficult to install?
The physical installation is straightforward for anyone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. After installing the new one, you will need to perform a simple security relearn procedure, which typically takes 10-30 minutes and does not require special tools.
Will this fix my specific problem?
This module is a direct solution for issues originating from a faulty PCM, including common DTCs like P0601 (Internal Control Module Memory Check Sum Error). While it resolves a vast majority of electronic drivability problems, we always recommend a proper diagnosis by a qualified technician to confirm the PCM is the point of failure.
Do I need to send my old computer back?
No, there is no core charge or requirement to return your old module. This is a direct purchase and replacement part.
What if I have another GM truck or SUV listed in the fitment?
This module fits a wide range of GM vehicles from that era, including the Chevy Colorado/Canyon, Trailblazer, and GMC Envoy. The programming process is the same: just provide us with the VIN for your specific vehicle, and we will program it accordingly.
