Restore Your GM Truck’s Dependability
Is your dependable GM truck, van, or SUV suddenly plagued by a persistent Check Engine Light, erratic performance, or a frustrating no-start condition? A failing Powertrain Control Module (PCM) is often the hidden culprit, disrupting communication between your engine and transmission and leaving you stranded. This VIN-programmed PCM is the definitive, hassle-free solution to restore your vehicle’s factory performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, this module is your answer:
- Persistent Check Engine Light (CEL) with codes like P0601 (Internal Control Module Memory Check Sum Error) or other communication-related faults.
- Rough or Unstable Idle: The engine struggles to maintain a consistent RPM at a stop.
- Stalling or Hesitation: The vehicle may stall unexpectedly or hesitate during acceleration.
- Poor Fuel Economy: A sudden, unexplained drop in MPG is a classic sign of an inefficiently running engine managed by a failing PCM.
- Failed Emissions Test: The PCM is critical for managing your vehicle’s emissions systems.
- Complete No-Start Condition: The engine cranks but will not fire up due to a lack of fuel or spark commands from the computer.
This professionally prepared programmed 16263494 PCM eliminates the guesswork and provides a reliable fix, ensuring your engine runs as the manufacturer intended.

An Expert’s Note on Programming
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched control modules. Simply grabbing a used computer from a salvage yard is a recipe for disaster. Critical functions like anti-theft systems (Passlock/VATS), transmission shift points, and fuel injector flow rates are all tied to the original VIN. Our process of flashing this programmed 16263494 PCM specifically to your vehicle isn’t just a convenience—it’s the only way to guarantee your truck or van operates safely and efficiently, just as it did when it left the factory.
Frequently Asked Questions
Do I need to do anything after installing this PCM?
In many cases, this is a plug-and-play installation. However, some GM vehicles of this era may require a security relearn procedure (for the anti-theft system) or a Crankshaft Variation Relearn (CASE). These are simple procedures that can often be done without special tools. Instructions can be readily found online or in a service manual.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Will this fix my transmission shifting problems?
The PCM controls both the engine and the transmission. If your shifting issues are caused by faulty electronic commands from a failing computer, then yes, this part will likely solve the problem. It will restore the correct communication and shift logic. However, it will not fix internal mechanical failures within the transmission itself.
Is this a new or used part?
This is a high-quality, genuine OEM module that has been meticulously inspected, tested, and prepared to ensure it meets or exceeds original factory performance. It provides the durability of an original part without the high cost of a new-from-dealer unit.
How can I be 100% sure this fits my vehicle?
The best way to ensure compatibility is to match the part number from your original module to one of the numbers listed (16263494, 16265035, etc.). You can also use the detailed fitment list provided in this listing. If you are still unsure, please contact us with your VIN before ordering, and we will be happy to verify the fit for you.
