Expert Insight: Why VIN Programming is Non-Negotiable
In the late ’90s, GM’s vehicle anti-theft systems (VATS/Passlock) became deeply integrated into the PCM. You can’t simply swap a computer from another truckโeven an identical oneโand expect it to work. The PCM, Body Control Module, and ignition key all need to communicate. Our VIN programming service correctly configures the GM 09355699 PCM for your vehicle’s specific options and security protocols, making the final installation straightforward and successful.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is the central computer, or ‘brain’, of your vehicle. It controls all aspects of engine and transmission function, including fuel injection, spark timing, emissions systems, and automatic transmission shifting to ensure optimal performance and efficiency.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your part without it. You can find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard near the windshield.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The most critical step after installation is performing the security relearn procedure, which can usually be done without special tools. Instructions are widely available online for your specific model.
Will I need to do anything else after installation?
After installing the programmed PCM, you will need to perform a security relearn procedure (often called a ‘key relearn’). This allows the new computer to recognize your vehicle’s anti-theft system and keys. This process typically takes about 30 minutes and does not require a mechanic.
Why should I choose a used OEM part?
Used OEM (Original Equipment Manufacturer) parts offer the best of both worlds: factory-grade quality and perfect fitment at a much lower cost than a new part from a dealer. This specific GM 09355699 PCM was designed by GM for your vehicle, guaranteeing compatibility that some aftermarket parts can’t match.
