An Expert’s Note on VIN Programming

As a technician, I’ve seen countless drivers buy a used computer from a salvage yard, only to find it won’t work because it’s still programmed to the donor car. This leads to a no-start condition due to the anti-theft system and incorrect engine parameters. Our process of pre-programming this 1999 Grand Am 3.4L ECM 9361733 to your VIN eliminates that entire headache. It’s the single most important step to ensure a successful, hassle-free repair, saving you time, money, and frustration.

Frequently Asked Questions

Do I need to do any programming myself?

No. We handle all the programming before we ship the part. The unit arrives ready for installation. You will only need to perform a simple security relearn procedure, which involves turning the key in the ignition and waiting for 10-12 minutes. We include instructions for this easy process.

Where do I provide my vehicle’s VIN?

After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.

How do I know this is the correct part for my car?

Please match the part number 9361733 from your original ECM to the one in this listing. Also, confirm your vehicle is a 1999 Pontiac Grand Am or Oldsmobile Alero with the 3.4L engine, as specified in the fitment guide.

What if my original part number is different?

If your part number does not match exactly, please contact us before ordering. Using the wrong module can cause performance issues or prevent the car from starting, even if it looks identical.

What does the security relearn procedure involve?

The GM security relearn (VATS/Passlock) is a simple process you can do yourself. It typically involves turning the key to the ‘ON’ position for about 10 minutes, then ‘OFF’, and repeating two more times. This allows your vehicle’s anti-theft system to recognize the new ECM. Full, easy-to-follow instructions are included with your order.

What does the warranty cover?

This unit is backed by our one-year replacement warranty. If the part fails within one year of the purchase date, we will provide a replacement unit. This gives you confidence in the quality and reliability of your repair.
