Restore Command of Your Hummer H3
Is your 2006 Hummer H3 feeling less like a dominant force and more like a frustrating puzzle? If you’re dealing with a no-start condition, a persistent check engine light, or performance issues that have sidelined your rig, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just another part; it’s the central command center for your engine’s performance and reliability. We offer the definitive solution: a professionally programmed 2006 Hummer H3 PCM that arrives ready for a straightforward installation, getting you back on the road and trail with confidence.
Common Symptoms & Your Direct Solution
A faulty PCM can cause a cascade of confusing issues. If your H3 is experiencing any of the following, this module is your solution:
- Complete No-Start Condition: The engine cranks but refuses to fire up.
- Erratic Engine Performance: Stalling, rough idling, hesitation, or sudden loss of power.
- Check Engine Light (CEL): Particularly for codes like P0601, P0602, P0606, or other internal controller errors.
- Poor Fuel Economy: A sudden, unexplained drop in MPG as the engine struggles to operate efficiently.
- Transmission Shifting Problems: Harsh or delayed shifts that aren’t related to the transmission itself.
- Communication Errors: Your mechanic’s scan tool is unable to communicate with the PCM.

An Expert’s Note on GM Security Systems
As a technician with over two decades of experience, I’ve seen countless DIYers get stuck after installing a used computer. On these GM trucks, the PCM is a critical part of the Passlock II anti-theft system. A module from another vehicle will not allow your H3 to start because it doesn’t recognize your key’s transponder. Our service eliminates this roadblock completely. By programming your VIN into the module *before* it ships, we ensure the unit is ready to communicate with your vehicle’s Body Control Module (BCM) and ignition system. All you’ll need to do is a simple 30-minute security relearn procedure (instructions in the FAQ below), which requires no special tools. This is the secret to a successful at-home installation.
Don’t let a faulty computer compromise the capability of your legendary truck. Take control of the repair with a reliable, professionally programmed 2006 Hummer H3 PCM and restore the power and dependability you expect. Order today and get your H3 back to conquering any terrain.
Frequently Asked Questions
Do I need to do any programming myself?
No. The unit arrives fully programmed to your vehicle’s VIN with the latest GM updates. The only step required after installation is a simple security relearn procedure, which does not require any special tools.
What is the security relearn procedure?
After installing the PCM, you will need to perform a key cycle relearn. Simply turn the key to the ‘ON’ position (without starting the engine) for 10 minutes, then turn it ‘OFF’ for 10 seconds. Repeat this process two more times for a total of 3 cycles (approx. 30 minutes). After the third cycle, the vehicle will start and run normally.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information to program the module correctly.
How do I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty PCM, this part is the correct solution. It’s crucial to ensure your vehicle has been properly diagnosed before ordering, as this part will not fix issues originating from other faulty sensors or mechanical components.
Is this a brand new part?
This is a high-quality, fully tested replacement component that has been expertly programmed to meet or exceed original factory specifications, ensuring reliable, long-term performance for your vehicle.
