Is your 2008-2009 GM Hybrid truck or SUV suffering from frustrating issues like a persistent check engine light, erratic shifting, stalling, or a no-start condition?

An Expert’s Insight: As a technician with over two decades of experience, I’ve seen many owners of these first-generation GM Hybrids chase phantom issues, replacing sensors and parts unnecessarily. The reality is that the complex communication between the gasoline engine and the hybrid electric drive is orchestrated entirely by the PCM. When it begins to fail, the symptoms can be incredibly misleading. A correctly programmed 12611182 PCM doesn’t just fix a single code; it restores the entire integrated system’s harmony, bringing your powerful and versatile truck or SUV back to life.
Frequently Asked Questions
Do I need to have this programmed by a dealer or mechanic?
No. The main benefit of our service is that this PCM arrives pre-programmed to the 17-digit Vehicle Identification Number (VIN) you provide. This allows for a straightforward installation without the need for specialized, expensive programming tools.
What information do you need from me after I order?
After you complete your purchase, you will need to provide us with your vehicle’s full 17-digit VIN. We cannot program or ship the module without it. This ensures the software we load is a perfect match for your vehicle’s specific options and systems.
Is the installation just ‘plug and play’?
For most vehicles, the installation involves disconnecting the battery, swapping the old module with the new one, and reconnecting the battery. However, some vehicles may require a ‘CASE Relearn’ or security relearn procedure to be performed with a capable scan tool for optimal performance and to sync with the vehicle’s anti-theft system.
How can I be sure my old PCM is the problem?
While the symptoms listed are strong indicators, the only way to be 100% certain is through proper diagnostics by a qualified technician. Key signs include a complete loss of communication with a scan tool, multiple unrelated error codes, or a confirmed internal processor fault code. This 12611182 PCM is the definitive solution for those confirmed failures.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM, then yes, this part will resolve the issue once the codes are cleared. However, if the light is on due to other failing sensors or mechanical problems, those issues will need to be addressed separately.
Which specific vehicles does this part fit?
This module fits 2008-2009 Chevrolet Tahoe & GMC Yukon with the hybrid option (M99), 2009 Chevrolet Silverado 1500 & GMC Sierra 1500 with the hybrid option (HP2), and the 2009 Cadillac Escalade with the 6.0L Hybrid engine.
