Is Your GM Truck or SUV Experiencing Frustrating Issues?
If your Cadillac Escalade, Chevy Silverado, or GMC Sierra is suffering from a persistent check engine light, erratic shifting, stalling, or a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. This vital component is the brain of your vehicle, and when it falters, it can cause a cascade of problems that leave you stranded and stressed. Stop guessing and replace the core of your engine management system with a reliable, correctly programmed solution designed to restore your vehicle’s performance and dependability.

An Expert’s Note on GM Programming
As a technician, I’ve seen countless issues arise from improperly programmed modules on these GMT800 platform vehicles. The PCM, often a P59 controller in this era, doesn’t just manage the engine—it’s in constant communication with the Transmission Control Module (TCM), Body Control Module (BCM), and anti-lock brake system. Using a generic or non-VIN-matched computer can lead to shifting problems, inaccurate speedometer readings, and even ABS faults. Our process of programming with the latest GM calibration for your specific VIN ensures all systems communicate correctly, just as the factory intended. This isn’t just a part; it’s a fully integrated solution for your vehicle’s electronic nervous system. The 2003-2006 Escalade ESV PCM 89017750 we provide is prepared to restore that factory-correct communication.
Frequently Asked Questions
Do I need to program this PCM?
No. We handle the programming for you before shipment. This module will arrive flashed with the latest GM updates tailored to the VIN you provide, saving you a trip to the dealership.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
How do I find my VIN?
Your VIN can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Is this a simple plug-and-play installation?
While the module is a direct physical fit and electronically programmed, most GM vehicles of this era require a security relearn procedure (often called a CASE relearn or anti-theft relearn) after installation. This is a simple procedure that can typically be done without special tools and takes about 30 minutes. Instructions are widely available online for your specific model.
Which vehicles does this part fit?
This PCM is compatible with a wide array of GM trucks and SUVs, including various years of the Escalade, Avalanche, Silverado, Sierra, Tahoe, Suburban, Hummer H2, and more. Please refer to the detailed compatibility list on this page to confirm it fits your exact model and year.
