Restore Peak Performance to Your GM Vehicle
Is your dependable Chevy truck, GMC van, or Cadillac SUV suddenly running rough, stalling, or refusing to start? A faulty Engine Control Module is one of the most common and frustrating problems for these workhorse vehicles. This Powertrain Control Module (PCM), service number 16263494, is the definitive, hassle-free solution to get you back on the road with confidence. We take all the guesswork out of the repair by professionally programming the module to your vehicle’s specific VIN before it ever leaves our facility. This ensures it communicates perfectly with your engine, transmission, and all related systems right out of the box.
Common Failure Symptoms & Your Direct-Fit Solution
A failing PCM can cause a cascade of confusing issues that can be difficult to diagnose. If your vehicle is experiencing any of the following, a faulty module is a likely culprit:
- Severe rough idling or stalling
- Complete no-start condition (engine cranks but won’t fire)
- Intermittent loss of power or hesitation during acceleration
- Poor fuel economy
- Harsh or erratic transmission shifting
- Check Engine Light with internal processor fault codes (e.g., P0601, P0605, P0606)
This programmed 16263494 PCM is the reliable, direct-fit answer to these problems, restoring the factory-grade performance and dependability you rely on every day.

From the Technician’s Bench: Why VIN-Specific Flashing is Crucial
“Back in the day, you might get lucky swapping a computer from one truck to another. On these GM vehicles, that’s a recipe for disaster. The PCM doesn’t just run the engine; it controls the transmission shift points, communicates with the anti-lock brakes, and even manages the security system. Our VIN programming process ensures the module has the exact software calibration your specific vehicle left the factory with, accounting for its engine size, transmission type, and even axle ratio. This isn’t just about convenience; it’s about making the repair correctly the first time and preventing potential damage to other expensive components.”
Frequently Asked Questions
What do I need to do after I purchase?
After you complete your purchase, you must send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot ship your order until we have this information, as we need it to correctly program the module for your specific vehicle.
Is this module truly “plug and play”?
Yes, for the vast majority of vehicles this module is designed for. Once programmed to your VIN, it will control the engine and transmission functions immediately upon installation. However, some vehicles may require a simple, unassisted “Security Relearn Procedure” to sync the module with your vehicle’s anti-theft system. This procedure typically involves turning the key on and off in a specific sequence and does not require any special tools.
How can I be sure my original PCM is the problem?
Common signs of a bad PCM include a no-start condition, erratic engine behavior, and specific diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error). While these are strong indicators, we always recommend a thorough diagnosis by a qualified mechanic to rule out other potential issues like wiring or sensor faults before ordering a new programmed 16263494 PCM.
Will this fix my check engine light?
If your check engine light is illuminated due to an internal fault within your original PCM, then yes, this replacement module will resolve the issue and allow the light to be cleared. If the light is on for another reason (like a bad oxygen sensor or a loose gas cap), that issue will need to be addressed separately.
Do I need to send my old module (core) back?
No core charge or return is required for this particular part. You can keep, recycle, or dispose of your old module at your convenience.
