An Expert’s Note on VIN Programming
On these late-90s GM vehicles, the PCM is more than just an engine controller; it’s the central brain. It communicates with the transmission, the anti-theft system (Passlock/VATS), the instrument cluster, and more. Installing a module without the correct VIN programming will, at best, result in a no-start condition and, at worst, can create a cascade of communication errors. Our VIN-specific programming service isn’t just a convenienceโit’s essential for ensuring your van operates exactly as the factory intended.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We handle all the programming for you before we ship. This 1998-1999 GMC Safari PCM will arrive at your door flashed with the latest GM software and coded to your specific VIN, making it ready for installation right out of the box.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your vehicle’s 17-digit VIN. You can also add it to the notes section during checkout. We cannot ship your part until we have this information.
Is the installation difficult?
For most individuals with basic mechanical skills, installation is straightforward. The PCM is typically located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in the reverse order. We always recommend disconnecting the battery for at least 15 minutes before starting.
What if my problem isn’t fixed after installation?
This module is guaranteed to fix any issues directly related to a faulty PCM. However, a vehicle is a complex system. If problems persist, it may indicate other underlying issues, such as faulty wiring, a bad sensor, or a mechanical problem that the PCM was correctly identifying. We recommend a thorough diagnosis to confirm the PCM is the root cause before purchase.
Will this fit other vehicles besides the GMC Safari?
Yes, this module is compatible with a wide range of GM trucks, vans, and SUVs from that era that use the same service number. Please check the detailed fitment list on this page to confirm compatibility with your specific make, model, and year.
