Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is the central computer of your vehicle. It controls all aspects of the engine and transmission, such as fuel injection, spark timing, and shift points, to ensure optimal performance, fuel economy, and emissions.
Is this module 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, and then installing the new one in reverse order. The specific location is noted in the fitment list (e.g., ‘LH front under battery’).
Do I need to do anything after installation?
In some cases, a security relearn procedure (often called Passlock or VATS) may be required, which can typically be done without special tools. A Crankshaft Variation Relearn (CASE) may also be needed to clear certain codes, which requires a capable scan tool. We recommend consulting a service manual for your specific vehicle.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check it for accuracy to avoid delays.
What if my old module has a different part number?
This module is a compatible replacement for several part numbers, including 12589462, 12602801, and 89017749. As long as your vehicle is on the fitment list, we will program this module to function perfectly for your application.
Why should I choose this over a generic module?
A generic or non-programmed module will not work in your vehicle. Our service of programming the 2005-2007 Express 2500 PCM 12589462 to your VIN saves you a trip to the dealer and the high cost of their programming services, providing a complete, ready-to-install solution.
