Frequently Asked Questions
Do I need to program this PCM?
No. We handle all programming for you before shipment. Simply provide us with your vehicle’s 17-digit VIN during or after checkout, and the module will arrive ready to install with the latest GM software for your specific car.
What is the security relearn procedure?
Most GM vehicles from this era have a simple anti-theft system (VATS or Passlock) that needs to sync with the new PCM. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this cycle three times. We include straightforward instructions to guide you through this easy process.
How do I know if this will fit my car?
This unit is compatible with a wide range of 1996 GM models listed in the fitment chart. The most important step is providing your VIN. Programming the module to your specific VIN guarantees it will function correctly, as if it came from the factory.
Will this fix my specific problem?
This module is the solution for issues directly caused by a failing computer, such as no-start conditions, stalling, communication errors, and erratic engine/transmission behavior. While it’s a very common point of failure, we always recommend proper diagnostics to confirm the PCM is the root cause before ordering a replacement 1996 Oldsmobile Eighty Eight PCM.
