Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM is sold as a fully programmed, plug-and-play solution. We handle all the flashing and software updates before the part is shipped to you, using the VIN you provide.
Where do I provide my vehicle’s VIN?
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 add it as a note during checkout.
Is this the right part for my car?
This unit replaces several service numbers, including 16236757 and 09356741. Please review the detailed compatibility list on this page and match the part number from your original module to ensure a perfect fit for your vehicle.
What about my car’s anti-theft system (VATS/Passlock)?
For many GM vehicles from this era, a simple security relearn procedure is required after installation to sync the new PCM with your car’s keys. This procedure takes about 30 minutes, requires no special tools, and we can provide you with easy-to-follow instructions.
How can I be sure my old PCM is the problem?
Common symptoms include a check engine light with communication-related codes, erratic engine or transmission behavior, and stalling. While these are strong indicators, we always recommend having a qualified mechanic perform a full diagnostic check to confirm the PCM is the point of failure before ordering.
