Expert Insight from Our Technicians
“Before you install your new PCM, take five minutes to inspect your vehicle’s main battery cables and engine ground straps. On these 90s GM trucks, a corroded or loose ground connection at the frame or engine block is a common cause of PCM failure. Ensuring these connections are clean and tight is the best insurance for protecting your new module and ensuring a lasting repair. It’s a simple step that can save you a major headache down the road.”

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential. It allows us to load the exact, correct software for your truck’s specific engine, transmission, and emissions equipment. This step is critical for ensuring the module works perfectly right out of the box.
Is this module difficult to install?
Installation is straightforward for anyone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one in reverse order. The entire process usually takes less than 30 minutes.
Will I need to do anything after installation?
Yes. After installing the PCM, you will need to perform a simple security relearn procedure, often called a ‘CASE learn’ or ‘Passlock relearn’. This syncs the new computer with your vehicle’s anti-theft system. This procedure does not require special tools and instructions are readily available online for your specific model.
Is this a new or used part?
This is a quality, inspected, and tested component that has been expertly programmed for your vehicle. We ensure every module meets strict functional standards before it is programmed and shipped.
What if this doesn’t fix my problem?
While this 1997 GM 4.3L PCM 16229684 is the solution for a wide range of issues, we understand vehicle diagnostics can be complex. If the module does not solve your issue, it may indicate another underlying problem (like a wiring short or a bad sensor). Our one-year replacement warranty covers the module itself for any defects.
