Common Symptoms of a Failing GM PCM & Your Solution
If you’re experiencing any of the following, a faulty engine computer is the likely cause. This module is designed to correct these exact problems:
- Check Engine Light: Persistent illumination, especially with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0604, or P0605.
- Erratic Engine Performance: Unexplained stalling, rough idling, misfires, or a noticeable drop in fuel economy.
- Harsh or Incorrect Shifting: The transmission may shift hard, get stuck in a gear, or shift at the wrong RPMs.

A Technician’s Note: Check Your Grounds Before Installing
As a veteran tech, I’ve seen countless PCMs get damaged by a simple, overlooked issue: a bad ground connection. Before you install your new module, take 10 minutes to inspect and clean the main engine-to-chassis and battery ground connections. A corroded or loose ground can cause voltage spikes that will permanently damage sensitive electronics, including your new PCM. This simple step is the best insurance you can get for a successful, long-lasting repair.
Don’t let a faulty computer keep your hard-working truck or van off the road. By providing us with your VIN upon purchase, you get a fully prepared component that solves the problem correctly the first time. This Programmed 16265035 Powertrain Control Module is your path back to a smooth, reliable, and powerful vehicle.
Frequently Asked Questions
Do I need to do any programming myself?
No. The main benefit of our service is that the module arrives at your door fully programmed to your vehicle’s VIN with the latest GM software. It is ready for installation.
How do I provide my VIN number?
After you complete your purchase, you can either add your VIN to the ‘notes’ section at checkout or reply to your order confirmation email. We cannot ship your part until we have the VIN to program it.
Will a security relearn be necessary after installation?
Yes, on most of these GM vehicles, a simple security relearn procedure (often called the Passlock or VATS relearn) is required to allow the vehicle to start. This procedure does not require special tools and typically involves a sequence of turning the key on and off. We can provide instructions for this simple process.
Is this compatible with my specific engine (4.3L, 5.0L, 5.7L)?
Absolutely. Because we program the module using your vehicle’s unique VIN, the software will be a perfect match for the specific engine, transmission, and options your truck or van was built with from the factory.
What if my original problem was a shorted sensor?
It is critical to ensure the root cause of the original PCM failure has been corrected before installing a new one. If a sensor or wire is shorted and feeding incorrect voltage, it can damage the replacement module. Always diagnose and fix related issues first.
Which part numbers does this module replace?
This module is a direct replacement for several service numbers, including 16263494, 16265035, and 8162634940, among others. As long as your vehicle is on the compatibility list, this part will work when programmed to your VIN.
