Important fitment and programming notice Please verify your original module number before purchase and provide your VIN so programming and fitment can be reviewed. When available, include the original module number or software ID, a clear module label photo, and photos of the original unit / connector side. Many GM vehicles require one or more post-install procedures such as theft-deterrent / security relearn, crankshaft variation learn, idle or throttle learn, transmission adaptive / fast learn, or module setup with a capable scan tool. Required relearns vary by vehicle, module type, and calibration. Our online catalog is an application guide, not an automatic fitment guarantee. Fitment is reviewed during programming, but the customer is responsible for confirming they are purchasing the correct part for their vehicle. Once programming, calibration retrieval, or supplier processing has started, related service costs may apply if the supplied vehicle or module information is incorrect.
