Is Your Northstar V8 Running Rough? Restore Peak Performance Today.
If you’re experiencing frustrating issues like stalling, erratic shifting, a persistent check engine light, or even a no-start condition in your 1996-1999 Cadillac or Oldsmobile, a failing Powertrain Control Module (PCM) is often the culprit. This central computer is the brain of your vehicle, managing everything from fuel injection and spark timing to transmission shift points. When it begins to fail, it can create a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs of other components. Don’t replace another sensor until you’ve considered the source. This replacement PCM, part number 19109039 / 16214848, is the definitive solution to restore your vehicle’s reliability and driving performance.
Common Symptoms of a Failing GM PCM
- ✔ Check Engine Light is on with various, often unrelated, trouble codes.
- ✔ Engine stalls unexpectedly or hesitates during acceleration.
- ✔ Vehicle refuses to start or has intermittent starting problems.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Noticeable decrease in fuel economy.
- ✔ Communication errors with diagnostic scan tools (U-codes).
- ✔ False warnings on the instrument cluster or dashboard.
The Direct Solution: Your Programmed 1996-1999 Aurora PCM
This isn’t a generic, one-size-fits-all part from a salvage yard. To ensure perfect compatibility and function, we flash this module with the latest GM-certified software updates specifically for your vehicle. The process is simple: after your purchase, you provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians then use this VIN to load the precise calibration file required for your car’s specific engine, transmission, and options. This critical step ensures that once installed, the PCM communicates flawlessly with all other modules in your vehicle, eliminating the performance issues and error codes caused by your old, failing unit. It arrives at your door ready for installation, taking the guesswork out of the repair.

Frequently Asked Questions
Why is providing my VIN so important?
Your VIN allows us to program the PCM with the exact software and calibration file your vehicle requires from the factory. This includes settings for the engine, transmission, anti-theft system (VATS), and other options. Without the correct programming, the vehicle will not start or run properly.
Is this module difficult to install?
Installation is generally straightforward for someone with basic mechanical skills. It involves disconnecting the battery, locating the old PCM (typically in the engine bay or under the dash), unplugging the electrical connectors, unbolting the unit, and then reversing the process with the new one.
Will I need to do anything after installation?
In many cases, you may need to perform a security relearn procedure, also known as a VATS relearn. This procedure is simple and involves a sequence of key turns in the ignition. It syncs the new PCM with your vehicle’s anti-theft system. Instructions are readily available online or in service manuals.
What happens if I don’t provide my VIN?
We cannot ship the PCM without your VIN. The programming is a mandatory part of the service to ensure the part you receive will function correctly in your vehicle. Your order will be held until the VIN is provided.
How can I be sure my original PCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis is best. Key signs include multiple unrelated error codes, communication loss with a scan tool, and having ruled out other components like sensors or wiring. If you’ve been chasing an electrical gremlin with no success, the PCM is the most likely suspect.
