Frequently Asked Questions
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot program and ship your 1997 Park Avenue PCM until we receive this information. Please double-check it for accuracy.
Is this module difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and installing the new one. However, after installation, you will need to perform a simple security relearn procedure (often called a VATS relearn) so the car recognizes the new module. This procedure can be done without special tools and instructions are readily available online.
Is this a true plug-and-play part?
Because it comes pre-programmed to your VIN, it is as close to plug-and-play as possible. The programming is done for you. The only additional step required by the vehicle’s anti-theft system is the security relearn procedure mentioned above, which is a necessary step for any PCM replacement on these models.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (such as with code P0601), then this module is the correct fix. It is always recommended to have your vehicle properly diagnosed to ensure the PCM is the source of the problem before ordering.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. If the module fails due to an internal defect within one year of the purchase date, we will provide a replacement unit.
