The check engine warning light comes on when the truck is started and the fault code is not cleared. The fault began when they installed a GPS and I disconnected the GPS and continues to throw the problem. I hope and support me with some data or advice how to diagnose

Are those codes setting in any other modules? The only thing on the lin bus from the pcm is the active grille shutters.

I would try bidirectional controls to the grille shutter see if it moves. I have a case study on a 17 Silverado that may help you. diag​.​net/msg/m6nlb3xosw…

Thank you very much if it turned out to be the active grille shutter actuator . AND In the photo the x105 connector is disconnected there is the graph with an oscilloscope

Hi Juan, Can you post the VIN number? There are 3 options for 2018 Colorado's in SI. The other questions I have - The Check Engine MIL is on? What "P" DTC is stored? Have you checked for DTC's across the "networks'? What are you using for a scan tool and do you have access to another tool?
