Hi, great videos, short and illustrative, please can you help me I will be very grateful it is in a 2013 Malibu car I followed the steps removed all the fuses, relays, microfuses and the short was not eliminated, removed the fuse box and the short is still there, I went to the fuse box that is inside the car, and the problem or the short was not eliminated, I disconnected the BSM, TCM, ECU, of the car and the same problem continues, what I noticed in some of the car fuses that are under the engine hood, by passing current it passes ground, of those that I remember are the ones for the headlights or headlamps, the error codes that the scanner returns to me are the following

please can you tell me if you know what elements or have the diagram of X1.
Scotty doesn't usually revisit topics he has already answered. If you cannot find a free wiring diagram online at a site like charm.li you could try a short-term subscription to ALLDATAdiy. Since AutoZone owns Alldata some of those stores may be able to print you out a copy of the wiring diagram you need at little or no charge.
That vehicle has so many problems. I would assume it has a bad main computer unless it's been flooded out and all kinds of things are shorted out. You won't get all those codes unless something's wrong with the main computer system to trip all those codes
@scottykilmer Thank you for your quick response, but I identified that I have a short circuit, I put my light tester, disconnect the terminal from the battery ground terminal, and connect the alligator clip to the battery ground terminal and put the tip of the tester on the ground terminal and the light turns on, and it turns on, which indicates to me that there is a short but I can't find a diagram that tells me that it feeds the X1 cable of the battery fuse box, since if I stop feeding current to X1 the short ends, please can you tell me if you know what elements or have the diagram of X1. Greetings and thanks in advance
Thank you
