Frequently Asked Questions
What information do you need from me?
After you complete your purchase, we require your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to program the 1997 GM Truck & Van PCM 16229684 specifically for your truck or van, ensuring a perfect match.
Do I need to have a mechanic install this?
While professional installation is always an option, this part is designed for a straightforward DIY replacement. The module is typically located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, removing it, and installing the new one in its place. Since it’s pre-programmed, no special tools are needed for setup.
Will this fix my Check Engine Light?
If the Check Engine Light is on due to an internal failure of the original PCM, this replacement will resolve the issue. However, it’s crucial to ensure that the codes are not being caused by a separate faulty sensor or wiring problem. We always recommend diagnosing the root cause of any trouble codes before replacing a module.
Is any other programming required after installation?
No. The unit arrives fully programmed and ready for installation. In some rare cases for specific models, a security or crank relearn procedure may be needed, which can often be performed without special tools. Instructions for this are widely available or can be provided by our support team.
How do I confirm this part fits my vehicle?
This 1997 GM Truck & Van PCM 16229684 is compatible with the extensive list of makes and models shown in the description. The best way to confirm is to match the part number 16229684 or 8162296840 from your original module. If you are unsure, please provide us with your VIN, and we can verify compatibility for you.
