Expert Insight: The Critical Role of VIN Programming
For these late-90s GM vehicles, the PCM is more than just an engine controller; it’s the heart of the vehicle’s security system, known as VATS (Vehicle Anti-Theft System). Simply swapping a computer from another vehicle will result in a no-start condition because the security information won’t match. That’s why our service is essential. By programming your specific VIN to this Programmed 9355699 PCM, we ensure the module is accepted by your vehicle, allowing for proper function and a straightforward installation. We handle the complex part so you can focus on the simple install.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot program or ship the computer without your VIN.
Is this a new computer?
No. This is a high-quality, used OEM computer sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested before being professionally programmed to ensure it meets strict performance standards.
Will I need to do any additional programming after installation?
In most cases, you will need to perform a simple security relearn procedure, which can be done without any special tools and typically takes 15-30 minutes. We can provide instructions for this process. This synchronizes the new PCM with your vehicle’s anti-theft system.
How can I be sure this will fix my vehicle’s problem?
While this PCM is the solution for the symptoms listed, we always recommend a proper diagnosis by a qualified mechanic. Ensure that wiring, grounds, and related sensors have been checked. A faulty PCM is a very common issue, but it’s important to confirm it’s the root cause of your specific problem.
