An Expert’s Note on Programming
“We once had a customer who bought a used, unprogrammed module for his ’99 Silverado. He spent a week chasing what he thought were fuel pump and ignition problems. The truck would start but immediately stall. The issue wasn’t mechanical; the unprogrammed PCM couldn’t communicate with the vehicle’s anti-theft system (Passlock). Our VIN-programmed 1999 Chevrolet 1500 PCM 09366810 would have solved his problem in under an hour. Proper programming isn’t just a convenienceโit’s essential for the vehicle to function at all.”
Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your exact vehicle.
Is any additional programming needed after installation?
In most cases, no. This module is sent programmed and ready for installation. However, some GM vehicles from this era are equipped with a Passlock or VATS security system which may require a simple key relearn procedure. This procedure can be done by you in your driveway in about 30 minutes without any special tools. We include instructions for this.
What is a PCM and why is it important?
The Powertrain Control Module (PCM) is the central computer of your vehicle. It controls all aspects of engine and transmission function, including fuel mixture, ignition timing, and shift points, to ensure peak performance, fuel economy, and emissions control. When it fails, the entire vehicle is affected.
How can I be sure this fits my vehicle?
Please check the extensive fitment list provided on this page. The most important step is to match the service number on your original module to one of the compatible part numbers listed (16250279, 09366810, 09355699). If you are unsure, please contact us with your VIN before ordering.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (common codes P0601-P0606), then this part is the correct fix. It is always recommended to have your vehicle properly diagnosed to ensure the PCM is the root cause of the problem before ordering a replacement 1999 Chevrolet 1500 PCM 09366810.
