An Expert’s Insight on PCM Failure
“After 20 years under the hood, I’ve seen countless PCMs like this one fail. It’s rarely a sudden event. The internal components, especially the capacitors, endure thousands of heat cycles. Over time, they degrade, leading to the strange, intermittent problems that are so hard to diagnose. Many people grab a used part from a salvage yard, but that’s a gamble—it could have the same issues or outdated software. A properly programmed unit like this 1997-2000 S10 Sonoma PCM 16228016 with fresh software isn’t just a part; it’s a permanent fix that brings these dependable older trucks back to life.”

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as each module is custom-programmed for a specific vehicle.
Is any additional programming needed after I install it?
No, this module is a plug-and-play solution. However, some vehicles may require a simple security relearn procedure, which involves turning the key on and off in a specific sequence. Instructions for this are readily available online or in your vehicle’s service manual and do not require special tools.
What makes this better than a used part from a junkyard?
A used part comes with an unknown history and may have the same internal flaws as your original. Our modules are thoroughly inspected, tested, and programmed with the latest GM software, which corrects earlier issues. Plus, this unit is backed by our one-year replacement warranty for your protection.
Where is the PCM located on my S10/Sonoma?
On most 1997-2000 S10, S15, and Sonoma models, the PCM is located in the engine compartment on the right-hand (passenger) side, often near the firewall or inner fender.
Will this fix my transmission shifting problems?
In many cases, yes. The Powertrain Control Module controls both engine and transmission functions. Erratic shifting, failure to shift, or harsh engagement can often be caused by a faulty PCM. This replacement will restore proper communication and control over the transmission.
