Is Your 1996 GM Vehicle Running Rough, Stalling, or Throwing Confusing Codes?
A failing Engine Control Module (ECM) can be the hidden cause of countless frustrating issues, from poor engine performance and erratic shifting to a complete no-start condition. If you’re tired of chasing electrical gremlins in your Pontiac Grand Am, Buick Regal, or Chevy Lumina, you’ve found the definitive solution. This direct-replacement ECM, compatible with service number 16231853, is the reliable heart your vehicle’s engine management system needs to get back on the road with confidence.
Common Symptoms & Your Solution
A faulty engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a failing module is a likely culprit:
- Check Engine Light with communication-related Diagnostic Trouble Codes (DTCs)
- Harsh or unpredictable automatic transmission shifting
- Poor fuel economy and reduced engine power
- Engine stalling, stumbling, or misfiring intermittently
- Complete failure to start, even with a good battery and starter

Expert Mechanic’s Tip
Before condemning your old ECM, take a moment to inspect your vehicle’s main battery cables and engine ground straps. On these mid-90s GM vehicles, a corroded or loose ground connection can cause voltage issues that mimic a computer failure. Ensuring your connections are clean and tight is a crucial first step that can save you time and money. A solid foundation is key to a healthy electrical system.
Frequently Asked Questions
How does the programming process work?
It’s simple! After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians will use this number to flash the module with the correct software and calibrations for your specific make, model, and engine. This ensures it communicates perfectly with your car’s systems.
Do I need to do anything after installing this 1996 Grand Am ECM?
While the module is programmed for your VIN, some vehicles may require a Crankshaft Position System Variation (CASE) relearn procedure. This is a simple process that can be done with a capable scan tool and helps the new computer synchronize with the engine’s sensors for optimal timing and misfire detection.
Is this compatible with other part numbers?
Yes. This module is a direct replacement for several service numbers, including 16231853, 88963800, and 16211539. If your original module has one of these numbers, this unit will work for your vehicle.
Why is a pre-programmed module better than a used one from a junkyard?
A used module from a junkyard is a gamble. It will be programmed for a different vehicle, has an unknown history, and may have the same internal faults as your old one. Our modules are tested, loaded with fresh, updated software specific to your car, and backed by a warranty, providing a reliable, long-term solution.
What information do you need from me?
The only thing we need is your vehicle’s VIN. You can typically find this on your driver’s side dashboard (visible through the windshield), on your door jamb sticker, or on your vehicle’s registration and insurance documents.
