A Technician’s Tip: Before replacing any computer, I always tell my customers to double-check the basics. Ensure your battery is fully charged and that the main power and ground connections at the battery, engine block, and chassis are clean and tight. A poor ground can mimic the symptoms of a failed PCM. Once you’ve confirmed your connections are solid and the problem persists, you can be confident that a new Programmed 16263494 PCM is the correct fix to restore your vehicle’s health.
Frequently Asked Questions
Is this part truly plug-and-play?
Yes, for most vehicles. Because we program the module to your specific VIN, it eliminates the need for a trip to the dealer. In some cases, a simple security relearn procedure (often called a CASE relearn) may be required after installation, which can typically be done without special tools. Instructions are widely available online for this process.
How do I provide my VIN?
After you complete your purchase, you can either add your 17-digit Vehicle Identification Number (VIN) to the order notes or we will contact you via email to request it. We cannot ship your part until we have your VIN to complete the programming.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of the existing PCM (common codes include P0601 – Internal Control Module Memory Check Sum Error), then this part will solve the problem. However, this Programmed 16263494 PCM will not fix issues related to other faulty components like sensors or wiring.
What’s the difference between an ECM and a PCM?
ECM stands for Engine Control Module, while PCM stands for Powertrain Control Module. For these GM vehicles, the PCM controls both the engine and the automatic transmission functions. The terms are often used interchangeably, but PCM is the more accurate description for this integrated computer.
Do I need to send my old part back?
No core charge or return is required for this part. You can keep or dispose of your old module at your convenience.
