Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No. This ECM arrives pre-programmed to the VIN you provide. It is designed to be a plug-and-drive solution, eliminating the need for specialized tools or a visit to the dealership for programming.
How do I provide my vehicle’s VIN?
Simply enter your 17-digit Vehicle Identification Number (VIN) in the notes section during checkout. If you forget, we will contact you after your purchase to retrieve it before we program and ship your module.
Will this fix my check engine light?
If your check engine light is on due to a faulty ECM, this part will solve the problem. However, it is always recommended to have your vehicle’s codes professionally diagnosed to confirm the ECM is the point of failure before ordering.
Is a security or CASE relearn required after installation?
In many cases, a simple security relearn procedure, which you can typically perform yourself without special tools, may be required for the vehicle to start. For optimal performance, a Crankshaft Variation (CASE) relearn using a compatible scan tool is recommended after any ECM replacement, just as a dealership would perform.
Is this the exact same part number as my original?
This unit is a fully compatible replacement for the original Programmed 12609441 ECM and other interchangeable part numbers. It is programmed to function identically to the factory module for your specific vehicle.
