Frequently Asked Questions
Do I need to have this module programmed?
No. We handle all the programming for you before we ship the part. All you need to do is provide us with your vehicle’s VIN at checkout, and we will flash the module with the correct software for your specific vehicle.
What information do you need from me?
After you complete your purchase, we will require your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the PCM correctly for your engine, transmission, and options.
Is any additional setup required after installation?
In some vehicles, a security relearn procedure (also known as a CASE relearn) may be required after installation. This is a simple process that can often be done without special tools and instructions can be found online or in a service manual.
My original part number is not 12602801. Will this still work?
Yes, this module is a direct replacement for several part numbers, including 12589462 and 89017749. As long as your vehicle make, model, and year are on our compatibility list, this unit will function correctly once programmed to your VIN.
Where is the PCM located on my vehicle?
The location varies. On Savana and Express vans, it’s typically in the LH rear of the engine compartment. On Silverado and Sierra pickups, it’s usually on the LH front, under or near the battery. Always disconnect the battery before attempting to replace the module.
