An Expert’s Note on Installation
As a technician, I’ve seen many jobs go sideways due to one missed step. For this ECM, the most critical post-installation step is the Vehicle Theft Deterrent (VTD) relearn. Your truck’s security system will not recognize the new ECM until this procedure is completed with a GM-compatible scan tool like TIS2WEB. It’s not a defect; it’s a security feature. Taking a few extra minutes to properly perform the VTD relearn, along with any other required setups like a crankshaft variation relearn, is the key to a smooth, successful, and permanent repair.
Frequently Asked Questions
What do I need to do after I purchase this ECM?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We cannot ship the part until we have your VIN to program the module correctly.
Is this module โplug and playโ?
No. While it is programmed for your VIN, it is not plug-and-play. You or your mechanic MUST perform a Vehicle Theft Deterrent (VTD) relearn procedure after installation. The vehicle will not start until this is completed. Other relearns, like for the crankshaft position sensor, may also be necessary.
What tools are required for the VTD relearn?
The security relearn procedure requires a professional-grade scan tool with access to GM’s programming system, such as TIS2WEB. This is typically performed by a qualified automotive repair shop or dealership.
Is this a new part?
No, this is a used, genuine OEM part that was carefully removed from a salvaged vehicle. It has been tested to ensure it is fully functional and ready for programming and installation.
How can I be sure this part will fit my vehicle?
