Is Your Hybrid Truck Plagued by Electrical Gremlins?
Nothing is more frustrating than a dependable work truck that suddenly won’t start, shifts erratically, or runs rough. For owners of 2004-2007 Silverado and Sierra 1500 pickups with the unique HP2 hybrid system, these issues often point directly to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s downtime that costs you time and money. This VIN-programmed PCM is the definitive solution to restore the performance and reliability you count on every single day.
Common Hybrid Truck PCM Failure Symptoms & Your Solution
A failing PCM can manifest in a variety of confusing ways, making diagnosis difficult. If your truck is experiencing any of the following, a faulty module is the likely culprit:
- Complete No-Start Condition: You turn the key, and nothing happens, or the engine cranks but never fires up.
- Erratic Shifting or Transmission Problems: The transmission may shift harshly, get stuck in a gear, or feel unpredictable.
- Stalling and Poor Engine Performance: Your truck may stall unexpectedly, idle roughly, or suffer from a noticeable loss of power and fuel economy.
- Persistent Check Engine Light: You may see stubborn diagnostic trouble codes (DTCs) like P0606 (PCM Processor Fault) or U0100 (Lost Communication With ECM/PCM) that won’t clear.
- Communication Failures: Your diagnostic scan tool may be unable to communicate with the vehicle’s computer.

An Expert’s Note on VIN Programming
“Many people think they can just grab a used computer from a junkyard, but for these specific GM hybrid trucks, that’s a recipe for disaster.

We configure the module to recognize every specific option your truck left the factory with, ensuring every component communicates correctly.

Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM is delivered to you fully programmed using the VIN you provide. The only additional step that may be required is a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be performed by a qualified mechanic, locksmith, or dealership.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you a message requesting your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Will this work on my non-hybrid Silverado or Sierra?
No, this module is specifically for models equipped with the hybrid option (RPO code HP2). Using it on a non-hybrid truck will result in system conflicts and improper operation. Please verify your truck has the hybrid system before ordering.
How can I confirm this is the right part number for my truck?
The best way to confirm is to check the service number on your original PCM. This unit is a direct replacement for service numbers 12583560, 19117215, and YBYZ. If your number matches, and your truck is a 2004-2007 Silverado or Sierra 1500 with the hybrid option, this is the correct part.
What is the warranty on this PCM?
This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
What tools are needed for the installation?
Installation is straightforward for someone with basic mechanical skills. You will typically need a set of metric sockets and a ratchet to access the PCM, which is located under the battery on the driver’s side. It is also highly recommended to disconnect the vehicle’s battery before beginning the installation of your 2004-2007 Silverado Sierra 1500 Hybrid PCM.
