An Old Workhorse Gets a New Brain
A local contractor brought in his ’99 Savana work van. It was his mobile office and tool shed, but it had started stalling unpredictably at job sites. He’d already replaced the fuel pump and ignition module with no luck. The problem was intermittent and costing him money. We diagnosed a failing PCM. Instead of a costly and time-consuming dealer visit, he opted for one of our pre-programmed units. After a straightforward installation and a quick security relearn, the van fired up and ran smoother than it had in years. He was back on the job the next day with a reliable vehicle he could count on, a perfect example of how the right Programmed 16258815 Engine Computer can be the simple fix for a complex problem.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle the main programming to your VIN before shipping. On some GM vehicles, you may need to perform a simple security relearn procedure, also known as a VATS relearn, which can typically be done in your driveway with just the key. Instructions are widely available online, and it does not require special tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we have this information, as it is required for the programming process.
Is this a new computer?
No, this is a high-quality used computer that has been carefully sourced from a salvaged vehicle. Each unit is inspected to ensure it is in good working condition before being programmed and shipped.
How can I be sure this will fix my vehicle?
While this part is the solution for a faulty PCM, it’s crucial to have your vehicle properly diagnosed by a qualified mechanic. A PCM can be damaged by other issues like a shorted sensor or bad wiring. Ensure the root cause of the original failure has been addressed before installing a new computer.
Will this fit vehicles other than the 1998 GMC Safari?
Yes, absolutely. This computer is compatible with a wide range of 1998-1999 General Motors trucks, vans, and SUVs that use service number 16258815 or the common ID 09355699. Please check the detailed fitment list on this page to confirm it matches your exact make, model, and year.
