Expert Insight: Why VIN Programming is Non-Negotiable
Back in the late ’90s, GM’s vehicle electronics became much more integrated. The PCM didn’t just control fuel and spark; it communicated with the anti-theft system (Passlock/VATS), the transmission, and the instrument cluster. Simply pulling a computer from a junkyard truck won’t work. The VIN programming process is critical because it loads the correct software for your specific engine, transmission type, gear ratio, and tire size. More importantly, it allows the PCM to communicate with your truck’s security system. Without this step, the vehicle will not start. Our service saves you the headache and expense of dealer programming, delivering a part that’s truly ready to install right out of the box.
Don’t let a faulty computer keep your truck sidelined. This professionally programmed 1998-1999 Chevy 2500 PCM 09355699 is the most effective way to restore the reliable performance you depend on. Get your vehicle running like it should.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM will arrive pre-programmed to the VIN you provide. The only thing you may need to do is a simple security relearn procedure, which takes about 10-15 minutes and involves cycling the key. We include instructions for this easy process.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to do this. We cannot ship your part until we receive and validate your VIN.
Will this fix my specific problem?
This module corrects issues directly caused by a failing PCM. While it solves a wide range of drivability and electrical problems, it’s essential to ensure your vehicle has been properly diagnosed. This part will not fix underlying mechanical issues or faulty sensors.
Is this the correct part for my vehicle?
This module replaces part number 09355699 and other compatible numbers listed. Please check the fitment list on this page and verify that your original module’s service number matches one of the compatible parts to ensure a perfect fit.
What is the security relearn procedure?
For most of these GM vehicles, the relearn procedure involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. This allows your vehicle’s security system to recognize the new PCM. Detailed instructions are included.
What does the warranty cover?
