Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module (PCM) is the central computer of your vehicle. It controls all aspects of the engine and transmission, managing everything from fuel injection and ignition timing to emission controls and transmission shift points to ensure optimal performance and efficiency.
Will I need to do anything after I install this part?
In most cases, this is a plug-and-play installation. However, some vehicles may require a security relearn procedure, also known as a CASE relearn. This is a simple process that can typically be done without special tools and instructions can be easily found online for your specific model.
How do I provide you with my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
