Frequently Asked Questions
Why do I need to provide my vehicle’s VIN?
Your Vehicle Identification Number (VIN) contains critical information about your truck’s specific options, engine, and transmission. We use the VIN to load the exact, correct GM software onto the ECM, ensuring it works seamlessly with your vehicle without any additional programming required.
Is this a simple plug-and-play installation?
Yes, for the most part. Because we program it beforehand, you will not need a dealer’s scan tool. You simply disconnect the battery, swap the module, and reconnect the battery. On some models, a simple security relearn procedure (often called a ‘key-cycle relearn’) may be necessary, which does not require any special tools.
Will this ECM fix my check engine light?
If the check engine light and performance issues are caused by a faulty ECM (e.g., codes P0601, P0606), then this part is the correct fix. It’s essential to have your vehicle properly diagnosed to confirm the ECM is the source of the problem before ordering.
