An Expert’s Diagnostic Tip
“Over my 20 years turning wrenches, I’ve seen countless customers replace expensive fuel pumps, crank sensors, and ignition modules, only to find the root problem was the PCM all along. A failing computer can send false signals, making other good parts look bad. Before you throw more parts at the problem, check for PCM-specific codes. This programmed 09355699 PCM often solves multiple issues at once, saving you from a frustrating and costly diagnostic journey.”
Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Is this part difficult to install?
Installation is straightforward for anyone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it from the vehicle, and then installing the new one in the reverse order. It’s designed to be a direct replacement.
Will I need to do anything after installation?
In many cases with these specific GM vehicles, you may need to perform a simple security relearn procedure to sync the new PCM with your vehicle’s anti-theft system. This procedure can usually be done without special tools and instructions are widely available online or in service manuals.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. PCM (Powertrain Control Module) is the most accurate term for this unit, as it controls both the engine and the transmission. ECM (Engine Control Module) and ECU (Engine Control Unit) are other common names for the same component.
