No. This ECM comes fully programmed to the VIN you provide. In most cases, it is a direct plug-and-play installation. Some vehicles may require a simple security relearn procedure, which can be done without any special tools. We include instructions for this common procedure.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). Please double-check it for accuracy, as the programming is specific to this number.
Is this a brand-new part?
No, this is a high-quality, used OEM part sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure it meets strict performance standards before being programmed and shipped.
Will this fix my check engine light?
If the check engine light is on due to a faulty ECM, this part will solve the problem. However, it’s crucial to ensure a proper diagnosis has been performed, as the light can indicate other issues. This 2013-2016 Acadia ECM 12633555 will resolve any codes directly related to the module itself.
