Expert Technician’s Insight
As a technician with over two decades of hands-on experience, I’ve seen countless vehicle owners waste time and money on used computers from a salvage yard. A PCM is not a one-size-fits-all part. Our process of programming this module with your specific Vehicle Identification Number (VIN) is the most critical step. It ensures all communication between the engine, transmission, anti-lock brakes, and security systems works exactly as the manufacturer intended. This prevents a cascade of compatibility issues and future headaches, making it the smartest, most reliable repair for your 2004 Escalade ESV PCM issues.
Frequently Asked Questions
Do I need to do any programming after I install this PCM?
No programming is required. However, on most GM vehicles of this era, you will need to perform a simple security relearn procedure. This can typically be done in your driveway with just the key and takes about 30 minutes. It involves turning the key to the ‘ON’ position for 10 minutes, three times in a row, to allow the new PCM to sync with your vehicle’s anti-theft system.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship the part until we have your VIN to program it.
How can I be sure this is the right part for my vehicle?
The best way to confirm compatibility is to check the service number on your original computer. This unit replaces service number 12586242 and the other numbers listed in the description. Matching one of these numbers ensures a perfect fit for your 2004 GM truck or SUV.
Will this fix my check engine light?
If the check engine light and associated fault codes are being caused by a faulty PCM, then yes, this part will resolve the issue. It is crucial to ensure that the problem has been properly diagnosed and that other components (like sensors or wiring) are not the root cause.
What is your warranty policy?
This unit is backed by our one-year replacement warranty. If you experience any issues with the module within one year of purchase, we will provide a replacement. Please contact us for assistance.
