Restore Peak Performance to Your GM Hybrid Truck
Is your Silverado or Sierra Hybrid suffering from frustrating issues like a persistent check engine light, poor idling, stalling, or a complete no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the electronic brain of your truck. Don’t let a faulty computer keep your reliable workhorse off the road. This direct-fit PCM is the definitive, no-hassle solution to get your truck running like it should, programmed specifically for your vehicle before it even leaves our facility.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of confusing and intermittent problems. If you’re experiencing any of the following, this module is your answer:
- Check Engine Light (CEL) Illumination: Often with communication-related codes (U-codes) or internal processor fault codes like P0601 or P0606.
- Engine Performance Issues: Stalling, rough idling, hesitation during acceleration, and a noticeable decrease in fuel economy.
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel injector or ignition coil command from the PCM.
- Transmission Problems: Harsh or erratic shifting, as the PCM plays a critical role in controlling transmission functions.
- Failed Emissions Test: An improperly functioning PCM can’t manage the engine’s systems correctly, leading to an automatic failure.
This pre-programmed 2004-2007 Silverado 1500 Hybrid PCM is engineered to resolve these issues permanently, restoring the communication and control your truck’s complex systems require.

An Expert’s Insight on PCM Failure
As a technician, I’ve seen countless 2004-2007 GM trucks with perplexing electronic issues. The P59-style PCM, like this one, is generally robust, but heat cycles and vibrations under the hood can eventually compromise internal circuits. Often, the drivers that control the ignition coils or fuel injectors are the first to fail. Grabbing a used module from a salvage yard is a gamble; it could have the same issue and will still require costly programming. This pre-programmed 2004-2007 Silverado 1500 Hybrid PCM eliminates that risk and guesswork, giving you a solid repair that you can be confident in from the moment you install it.
Frequently Asked Questions
Do I need a dealer to program this PCM?
Absolutely not. The main benefit of our service is that we program the module to your truck’s specific VIN before we ship it. It arrives ready for installation, saving you time and the high cost of dealer programming.
What is the security relearn procedure?
After installation, you will need to perform a simple security relearn, which takes about 10-12 minutes and requires only your key. The process involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’, and repeating two more times. This allows your truck’s anti-theft system to recognize the new PCM. Instructions are included.
Where do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Will this work on my non-hybrid Silverado?
No, this particular module is specifically for models equipped with the hybrid option (GM RPO code HP2). While it may look physically similar to other PCMs, the software and internal calibration are unique to the hybrid system. Please verify your vehicle has the hybrid option before ordering.
What if my original part has a different service number?
This module, hardware number 12583560, is the correct replacement for the service numbers listed, including 19117215 and YBYZ. Service numbers often change over the years, but the core hardware and programming we provide will be a perfect match for your vehicle.
