Restore Command and Capability to Your Hummer
Is your 2006 Hummer H3 feeling less like a rugged, go-anywhere machine and more like an unpredictable source of frustration? If you’re dealing with a persistent check engine light, erratic engine behavior, or transmission issues, the problem often lies with a failing Powertrain Control Module (PCM).

We provide a definitive, reliable solution: a professionally programmed 2006 Hummer H3 PCM that arrives ready for installation, getting you back on the road and trail with confidence.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways, leaving you stranded or dealing with poor performance. If you’re experiencing any of the following, this module is your answer:

- Erratic Shifting & Transmission Problems: Harsh shifts, getting stuck in gear, or failure to shift at the correct RPMs.
- Poor Engine Performance: Noticeable loss of power, rough idling, stalling, and decreased fuel economy.
- Check Engine Light (CEL): Often accompanied by Diagnostic Trouble Codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error), P0606 (PCM Processor Fault), or various communication errors.

An Expert’s Note on VIN Programming
“In a vehicle as complex as the Hummer H3, the PCM is the master conductor of an electronic orchestra. Simply installing a generic or used module without proper VIN programming is a recipe for disaster. It can lead to security system lockouts (preventing the vehicle from starting), incorrect transmission shift points, and even long-term damage. Our VIN-specific flashing process ensures every component, from the anti-lock brakes to the throttle body, operates in perfect harmony as the manufacturer intended. It’s the critical step for a lasting, reliable repair.”
Don’t let a faulty computer sideline your capable SUV. This programmed 2006 Hummer H3 PCM is the most dependable way to restore your vehicle’s core performance and get you back to your adventures.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module comes fully programmed to the VIN you provide during checkout. It is a plug-and-play installation. In some cases, a security or crank relearn procedure may be required, which can be done with a capable scan tool or by following a simple manual procedure.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. You can also add it to the ‘notes’ section during checkout. We cannot ship your part until we have this information.
Where is the PCM located on my 2006 Hummer H3?
On the 2006 Hummer H3, the Electronic Control Module (PCM/ECM) is typically located on the right-hand (passenger) side of the firewall in the engine bay.
Will this computer fix my check engine light?
If the check engine light is caused by an internal fault in your old PCM (like a P0601 or P0606 code), this part is the correct fix. However, if the light is on for another reason (e.g., a bad oxygen sensor), you will still need to repair that underlying issue. This module will solve any problems directly related to the computer itself.
What if I have an issue with the part after installation?
Your purchase is protected. This unit is backed by our one-year replacement warranty. If you encounter any issues with the module itself, please contact us, and our support team will be ready to assist you.
