Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the latest GM software and flash the module specifically for your vehicle’s configuration before it ships. This makes the unit ready for installation upon arrival.
Do I need to do a security or CASE relearn after installation?
In many cases, a security relearn procedure is required after installation for the vehicle to start. This is a simple procedure that typically involves cycling the key in the ignition and can be done without special tools. A Crankshaft Variation (CASE) relearn may also be necessary to clear certain trouble codes, which requires a capable scan tool.
What does the PCM actually do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls the engine’s fuel injection, ignition timing, emissions systems, and the transmission’s shift points. A properly functioning PCM is essential for optimal performance, fuel economy, and reliability.
