Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive and validate your VIN.
Is any additional programming required after installation?
In most cases, no. Our VIN programming makes this a plug-and-play installation. However, some vehicles may require a simple security or crankshaft position sensor relearn procedure, which can often be done without special tools. Instructions can be provided if necessary.
My original part number is 12633055. Will this work?
Yes. This ECM, part number 12633238, is a direct replacement for part number 12633055 and other compatible numbers. As long as your vehicle is on the fitment list, we will program it to work perfectly.
What is the difference between an ECM, ECU, and PCM?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the same component. A PCM (Powertrain Control Module) is an integrated unit that controls both the engine and the transmission. For your vehicle, this part serves as the central engine computer.
How can I be sure the ECM is the problem?
While the symptoms listed are strong indicators of a failing ECM, it’s always best to have a qualified mechanic perform a full diagnostic. This includes checking wiring, grounds, and power supplies to the module to rule out other potential issues before replacement.
