Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module with your vehicle’s VIN before shipping. It is designed to be a plug-and-drive solution. In some cases, a simple security relearn procedure, which involves turning the key, may be necessary. This does not require any special tools.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on where to send your VIN. We cannot ship your part until we have this information, as the programming process is essential.
Is this the same as an ECM or ECU?
Yes. The terms Powertrain Control Module (PCM), Engine Control Module (ECM), and Engine Control Unit (ECU) are often used interchangeably for this component. It is the main computer that controls your vehicle’s engine and transmission functions.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of your existing 2006 GMC Envoy engine computer, then this part will solve the problem. It is crucial to have the vehicle properly diagnosed to ensure the fault lies with the computer and not a different sensor or component.
