We provide a genuine Programmed GM 16263494 Powertrain Control Module, professionally flashed with the latest official GM software updates and coded specifically to your vehicle’s unique Vehicle Identification Number (VIN). Stop chasing symptoms and install the definitive fix that restores your vehicle’s performance and reliability.
Common Symptoms & Your Direct-Fit Solution
A failing PCM can cause a wide range of issues that can be difficult to diagnose. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Persistent Check Engine Light (CEL): Especially with codes like P0601 (Internal Memory Error) or P0606 (PCM Processor Fault).
- No-Start or Intermittent Starting: The engine cranks but refuses to fire up, or does so unpredictably.
- Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- Erratic Transmission Shifting: Harsh shifts, slipping out of gear, or getting stuck in one gear.
- Failed Emissions / Smog Test: The PCM is critical for managing your vehicle’s emissions systems.
- Stalling or Rough Idle: The engine may die at stops or run poorly for no apparent reason.
This professionally programmed module is the most reliable way to solve these issues. By providing your VIN upon purchase, you receive a unit that is perfectly matched to your vehicle’s factory specifications, eliminating the need for expensive dealership programming or specialized tools.

A Technician’s Perspective: Why VIN Programming is Non-Negotiable
As a tech who’s seen it all, I can’t stress this enough: grabbing a random computer from a salvage yard is a recipe for disaster. On these GM vehicles, the PCM controls everything from the fuel injectors to the transmission shift points. It needs to know your exact gear ratio, tire size, and whether you have A/C or four-wheel drive. Our VIN-programming process isn’t just a convenience; it’s a critical step that loads your vehicle’s exact DNA onto the module. This is how we can guarantee it will work correctly the first time, every time, saving you from days of headaches and diagnostic dead ends. This is the professional way to do the job.
Don’t let a faulty computer keep your workhorse off the road. By installing this Programmed GM 16263494 Powertrain Control Module, you are restoring the very core of your vehicle’s operational integrity. Get your truck or van running right again.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module is sold as a plug-and-play solution. We handle all the programming based on the VIN you provide, so it’s ready for installation as soon as you receive it.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will send you a message requesting your VIN. Simply reply to that message, and our technicians will program the module before shipping it out.
Will I need to perform a security relearn procedure?
Yes, on most GM vehicles of this era, a simple security relearn (often called Passlock or VATS) is required after installation. This procedure is easy to do, requires no special tools, and typically takes about 30 minutes. We can provide instructions upon request.
What if my original part number is not 16263494?
This module is a direct replacement for several part numbers, including 16265035 and 8162634940. As long as your vehicle is on the compatibility list, we will program the module to function perfectly as a replacement for your original unit.
How do I know for sure that my old PCM is bad?
While a professional diagnosis is always best, common signs include specific trouble codes (like P0601), a no-start condition where you have spark and fuel, and multiple unrelated sensor codes appearing at once. If you’ve checked your wiring and sensors, the PCM is often the final piece of the puzzle.
