Expert Insight: The Work Van That Wouldn’t Work
We recently worked with a contractor whose 2003 Savana van was his mobile office. It started stalling at intersectionsโa dangerous and costly problem. His mechanic replaced sensors and plugs, but the issue persisted. The problem was a failing PCM causing intermittent fuel control faults. Instead of towing it to a dealer and losing days of work, he ordered a Programmed GM PCM 12581565 from us. After providing his VIN, the part arrived ready to install. In under an hour, his van was running perfectly, with a smoother idle and no more stalling. He was back on the job the next day, saving hundreds in diagnostic fees and lost income.
This module is a direct replacement for multiple service numbers, including 12581565, 12570557, 12576106, and more. Please verify your part number or consult our fitment list to ensure you’re ordering the correct component for your vehicle. Getting a Programmed GM PCM 12581565 is the most efficient way to solve complex electronic issues and restore your vehicle’s factory operation.
Frequently Asked Questions
Is this module truly “plug and play”?
For most vehicles, yes. Because we program the module to your VIN, it will sync with your vehicle’s systems upon installation. However, in some GM vehicles, a security relearn procedure (often called Passlock or Passkey) may be required, which can typically be done without special tools. A CASE (Crankshaft Angle Sensor Error) relearn may also be needed, which requires a capable scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically reply to your order confirmation email or follow the instructions provided after checkout. We cannot ship the part until we have your VIN.
What if my original part number is not on your list?
GM often uses multiple service numbers for the same physical part. The numbers listed (like 12581565, 12570557, 12576106, etc.) are all interchangeable for the applications shown. As long as your vehicle make, model, and year are on our compatibility list, this module will function correctly once programmed.
What common issues does this part fix?
This PCM is the solution for a wide range of problems including no-start conditions, random stalling, poor engine performance, harsh shifting, false check engine lights, and communication errors with scan tools.
Do I need to send my old computer back?
No core charge is required for this part. You do not need to return your original, non-functioning module to us.
What is the warranty on this computer?
This unit is backed by our one-year replacement warranty. Please see our warranty page for full details and conditions.
