Check if the computer is being powered-up. It won't communicate if its not powered-also check all the fuses

Already checked all fuses, HE TREATED WITH VARIOUS SCANNERS All it does is put CONNECTION ERROR, EVEN PUT YOU ANOTHER COMPUTER WHICH IS LOCATED IN THE PILOT SIDE Fenders, BUT DID THE SAME FRAME CONNECTION ERROR.

P. S. NOT BE REFERRED TO CHECK THAT IF THE UNIT IS ON.

Thank you for answering in advance.
