Important Installation Notes
This ECM requires programming/flashing with the newest updates from GM using your VIN. After purchase, provide us with your VIN so we can program the ECM before shipping. This computer is used and came from a salvaged vehicle. Note: Upon installation if the vehicle does not start, a theft relearn will need to be done using the GM programming system tis2web.
It’s the buyer’s responsibility to do the vehicle theft deterrent relearn, as well as any other relearns or setup procedures (e.g., injector setup, crankshaft variation relearn). This ensures security features align perfectly and provides a reliable fix for your 2018 – 2020 Terrain.
