Frequently Asked Questions
What information do you need from me?
After you complete your purchase, we will need you to provide your vehicle’s 17-digit VIN (Vehicle Identification Number). This is essential for us to load the correct, vehicle-specific software onto the module before shipping.
Is this a difficult part to install?
For someone with basic mechanical skills, the physical installation is typically straightforward. The ECM is often located in the engine bay, secured by a few bolts and electrical connectors. Since our module comes pre-programmed, you skip the most difficult software-related steps. We always recommend disconnecting the battery before starting work.
Will this fix my specific check engine light codes?
This ECM is a common solution for a wide range of powertrain and communication-related Diagnostic Trouble Codes (DTCs). While it can resolve many issues, it’s crucial to ensure your vehicle’s problem has been properly diagnosed. This part will not fix underlying mechanical or wiring issues.
Do I need to have my keys reprogrammed?
In many GM vehicles of this era, the security information is stored in the Body Control Module (BCM), not the ECM. Therefore, in most cases, no key reprogramming is necessary. The vehicle should start and run once the new ECM is installed.
What does the one-year warranty cover?
This unit is backed by our one-year replacement warranty. This means that if the module fails due to an internal defect within one year of the purchase date, we will provide a replacement unit.
