Expert Insight: Avoid the Parts Cannon
As a technician, I’ve seen countless owners waste hundreds of dollars replacing perfectly good sensors and components because they were chasing symptoms caused by a failing ECM.

By installing a correctly programmed 1999 Grand Am ECM 09361733, you are fixing the brain of the operation, not just a symptom.
Frequently Asked Questions
Do I need to do any programming to this computer?
No. This ECM is delivered to you fully programmed. After you place your order, you simply need to provide us with your vehicle’s VIN. We handle all the flashing and software updates before it ships, making it ready for installation right out of the box.
Where is the ECM located on a 1999 Grand Am or Alero?
The Engine Control Module is typically located inside the vehicle, behind the dashboard on the driver’s side (LH center dash). Access may require removing lower dash panels.
What information do you need from me after I order?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to load the exact, correct software calibration for your specific vehicle configuration.
Will this fix my check engine light?
If the check engine light is on due to an internal fault within your original ECM (such as a P0601 code), this replacement unit is designed to correct that issue. It’s crucial to ensure the root cause of the problem is the ECM itself.

This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
